A few days ago Dave (HDFXR3) mentioned that he has a 150mm tire on his 1999 FXR3. 

I am sure many of us would be interested in this discussion:

HDFXR3  August 09, 2008,
I might add another item to those of you who are modifying these fxr3 blue babes. When i bought my fxr3 blue it had a 150 tire on  the rear..and i replaced it several months ago w/ the same. you can put 150 tire on rear of fxr3, i'm currently riding on one, one change that was made was reversing strut bolt..so nut is outside..with head inside of rear fender. It looks good and rides great!  i really like a little more rubber on the road anyway...look what is going on with current bikes.  dave

----------------------------------------------------------------------------------------------------------------

From FXR2evo99:

A Photo of the above would be worth a 1000 words....lol and be quite helpful!!!
Ummmmm would this work for the FXR2 too huh huh huh would it.....well would it.....lol.....
Don't tell me you guys are leaving us FXR2 boys and girls out in the rain......come on now.....lol.....
 
Talk to me Dave.....inquiring minds need to know this.....can a 150 fit on my FXR2? ?   
   
So you have no rubber fighting with the walls of the fender....everything runs smoothly....no rubbing whatsoever?
I had a 150 on my 2003 Dyna Low Rider and of course I liked the looks of it....

Ok so tell me does having a 150 rear tire affect handling in a negative way on these bikes....just curious....perhaps a silly question but enlighten me on this please....

Regards,

Tim

----------------------------------------------------------------------------------------------------------------

From Hoist:

Yeap, me too!

Wasn't even sure a 140 fit. I've used 1 size over on wheels for years, but never went 2 sizes over. Normally you'd use a wider wheel too. You're using a 150 on a stock wheel? Yeap, tell us more please!

Hoist!


----------------------------------------------------------------------------------------------------------------

HDFXR3
I'll post some pictures in a day or so of my fxr3 w/ 150 mounted on stock wheel. i think it looks great and no rubbing on belft or fender, its full fender look. only  thing i know was changed was strut bolt reversed so nut is outside..besides the nut in seat! hehe...........Dave


----------------------------------------------------------------------------------------------------------------


So I thought I would simply list this in a "Thread" by itself so that others might be able to locate it.....lol and I am not calling "Dave" out....laughing.....it's just that in the other thread we have so many things going on that I thought "compartmentalizing" this one would serve a good purpose....

Dave, I am also interested when you do get to this, exactly what rear tire you are using on your FXR3.  Brand Name and Model# as most of us realize these manufactuerers have a thing with describing something in their model numbers as a certain size but then when you look and study the "specific" "specifications of the tire, they can be exteremely different in terms of tire diameter and tire width.  So if any of us are to decide to follow suit it would be good to know exactly what is installed on your bike.  Then there is the matter of whether you are also running the belt guard or did you remove it.....what I would think all of us are after is what was done exactly so if we privately invest in a 150mm tire we will know that we followed what you are doing carefully..... As we all know there isn't that much room in and around that fender.

So I am excited to see what we come up with here.....I use to have as I mentioned before a 150mm tire on my 2003 FXDL, and of course when HD brought out the 2002 FXDL they began with the 150mm tire but one of the modifications for that bike was also a wider fender so I am curious of course what brand of tire you are implementing and curious how it fits with out the additional "width" of a rear fender.

I know that above you mentioned flipping the bolts around at the location of the strut(s) and obviously this creates some additional room, [Did you do this to both sides of the bike's struts] I have looked at my bike and this is beginning to make sense but look forward to you posting some photos of how you are running with this modification.

Also another question, how does running the 150mm tire do for handling, you mentioned that you like having a bit more rubber on the road.....so my question is at what width tire does one reverse the positive effect of extending the width of their tire.....I am just curious....

I know that I have had certain debates/discussions about the merits of running a 19" front tire on my FXR2 [as most of you know the FXR2 comes with a 21" laced wheel] just like the FXR3's and FXR4's and there always seems to be a debate about whether running the 19" is an improvement or not?  I would enjoy a discussion about that as well.....if any are up to the discussion....it may be brief as perhaps everyone has some strong opinions about it.....but that's great....

I just think it would be good to have the idea of what is the best width tires to be running on our bikes.....now when we get into whether it's a Dunlop, Metzler, or Avon, or _________ is really not the intent I have here....

Ok so I am waitin......and excited to learn more about this topic....

Tim

well, took my blue 3 to work this am..for pictures, close ups of 150 combo. Made a discovery in shooting them..that my rear sprocket and belt is narrower than the fxr4 parked here for sale. hmmm. of course i bought this used w/ 5k miles on her and never noticed till t his am..that sprocket was changed and belt was also..it makes sense. i'm going to post pics of this for your info. apparently 5 star thunderstar sprocket was changed and narrorer belt....so no rubbing of belt and tire..and nice full fit of tire in fender. parts book i have doesn't give width of belt..just part number. here are the photos.....dave

thanks for flipping vertical shots, prior to posting they were not vertical, maybe my camera auto rotates. if any other shots needed let me know. i'm trying to get shot from underneath..to show space. its tight fit..but no rubbing at all of belt on tire, or tire on fender. i would say she handles better with the larger tire..Dave

Dave,

Can you take one of the rear wheel sprocket side showing the whole bike....so we can get a "Depth" perception of how your rear sprocket actually looks in conjunction with the bike...

I will delete this post after you do so.

Thanks

Dunlop 401  150/80B-16  <~~~What is currently on Dave's [HDFXR3] FXR3 right now as he has shown above, even though he typed in "30" above he meant "80", ie: typo error

Overall Tire Height:
25.45"    646.430mm

Overall Tire Width:
6.15"     156.210mm

Which means technically this tire is over 150mm wide.....that's why you have to look at the specs of each tire to see what the manufactuerer is really doing.

Tim

here is shot from left side...#1

[FXR2evo99]

So Dave,

I am sure someone will ask but what's the type of finish on your rear wheel sprocket, it looks like it is a corse type of "silver" powdercoating?

Tim

[hdfxr3]

shot #3 of left side...and i'll check sprocket for finish....hmmmm

[FXR2evo99]

You need a mircometer to measure really well....also it would be interesting how wide your belt is as well.
You take fantastic photos.....and your bike is gorgeous.....so now we all need to know how much room you gained going to a different belt width and rear sprocket? ? ? ? ?

sprocket is thunderstar design w/ matte finish on inside, outer flange is chrome. now i'm curious if stock sprocket is same as mine or not, i'll check Gregs bike and see if and how his is different..and reply later.  dave

[Hoist!]

HeHe! Kept looking like you were done. It appears you are now.

Thanks for all them great shots, closeups and info Dave, and for flipping them Tim!!! I like how it fills up the inside of the fender. Looks great back there!

You bought yours that way, bonus! I'm not sure it's worth all the effort to replace the belt and sprocket, respace the rear wheel (maybe?), and all the work and $$$ involved in doing that, when you can just put a 140 on. You have it and I love it, but I'm not going thru that effort myself. Thanks very much Dave for posting all the pics. Makes things very clear!

But man, that indicator light console's got to go on mine!

And I think someone needs some chrome acorn nuts on them reversed strut bolts!

Hoist!

[hdfxr3]

Since this is the way she was when purchased, i did not realize how much modification was done, and it still looks stock. even though cvo's come loaded w/ goodies..we can sure modify them to suit us! Thank God we are all different and have ideas on how we want these to look and perform! Please excuse my dirty bike shots, not had time to wash her and detail, more fun to ride! This site allows us to share experiences..and very educational.  dave

That's what I was thinkin' as I looked at the photos!   Would really make the whole deal look factory that way.  Great shots, Dave!  Just from the photos you can really tell it's a lot wider than my stock 130.   I love it!

[FXR2evo99]

He DON'T NEED NO STINKIN "CHROME" NUTS!!!!! 

HE IS OLD SCHOOL!!!!!!

Just going back through the great pictures of Dave's bike and picked up on these comments.

That's just the way they are.   Here's a photo of mine.  I guess it's because they're not the "mirror chrome" thunderstars, just the regular ones.  Mine is very rough finish on the spokes with only the very edge being a polished finish.  Apparently, they came in different widths for whoever did Dave's conversion to the narrower belt.

(Yes, that is some rust water that must've dripped down there!   I'll get right on that!!! )

[FXR2evo99]

Ok.....now I am confused, do you Dave or does Dave have a "OEM" rear wheel thunderstar sprocket or not on his bike and in the above photographs? 

Brian do you have a "OEM" rear wheel thunderstar rear wheel sprocket or not?

IF not what do you both have?

Tim

I have OEM.  Thought you were asking about the finish on Dave's narrower sprocket.  It's the same as mine (OEM).

Now I'm confused.

[Hoist!]

Mine looks the same too. I didn't think HD offered it narrower?

Hoist!

[FXR2evo99]

Brian you need to almost take a photo just like Dave's photo in post #33, ie: same angle and same distance to see how the light reflects it....

YOU GUYS ARE CRACKIN ME UP.......UMMMMMM DO YOU THINK WE SHOULD KNOW WHAT IS ON YOUR BIKES....LAUGHING......ie: OEM THUNDERSTAR REAR SPROCKETS OR PERHAPS AFTER MARKET.....if he would take a micrometer (sp) to the outside demension of the rear wheel sprocket as well as the actual belt that probably would help us........I will go measure mine right now and the width of my rear wheel sprocket......

You guys are funny.....ummmmm duh what do we have here....ummm well it looks like a sprocket so let's go ride.....LOL

Well it looks like I have a 1 1/2" belt rear drive (secondary belt)

 

Regards,

Tim

[FXR2evo99]

Dave.......

Here is what we needed to see more of from photograph #15, the ability to see what the proximity of the belt and the tire as to how close they might be rubbing....that would give us all a visual as to what's going on with your belt guard edge and the tire side wall.

Currently on my 1999 FXR2, the actual distance between the two yellow arrows is 3.5mm before I begin touching that "thin mud flap" that protects the side of the tire from rubbing the side of the rear wheel sprocket edge....which means I have another 3.5mm on the other side providing me with a maximum of 7mm additional tire room.....I measured the distance between the yellow arrows while my tires were on the ground fully...that's probably an important measurement to make sure one's tires are on the ground when measuring the space between the edge of the rear sprocket and the side wall of the tire. 


THIS IS THE CURRENT TIRE I AM RUNNING:
Metzler 130/90HB-16

Overall Diameter Height:
25.43307”  25 7/16”    646mm

Overall Width:
 5.3937007” 5 3/8”     137.mm


So the tire width I am running is 137.000mm + 7mm = 144mm wide maximum for the way my bike is running which would mean the following tire:

Dunlop 402  MU85B16

Overall Diameter Height:
 25.71"      653.034mm

Overall Width:
  5.51"       139.954mm



The 140/90 Metzeler has an advertised width of 146mm.
146mm * 0.90 = 131.4mm sidewall height.
The calculated difference in sidewall height is 12.44mm or 0.49".
Based on this, the 140/90 Mezeler should be nearly 1" taller in overall diameter. But, the advertised overall diameter of the MU85 is 25.71" and that of the 140/90 is 26.18"...a difference of only 0.47".


Looks like I am getting somewhere.....lol

Tim

wow, this is up for more discussion. my belt is and  1 inch and a 1/16 in width, sprocket just little wider. i just compared fxr4 i have up for sale and the belt width on it is 1.5 inches..obvious difference..so i then examined my sprocket..and it fits the belt exactly as far as width. the thunderstar sprocket i have looks identical to other one posted on here..but is narrower. i'll shoot another shot or two tomorrow am ..before i go for a ride..so as to show space between belt guard and tire. my mud flap has been removed..as far as i can see, but black belt guard and chrome cover is there. i have more distance betweeen between my belt and belt guard then you'all..because my sprocket is almost 1/2  inch narrower..ie more room..no rubbing at all. and my bike is on ground.not jacked up. this is 2nd fxr i've had that had had 150 tire on it..had fxr4 tangerine couple of years ago ..and previous owner had installed 150 on it. i'm checking with current  owner as to width of sprocket and width of belt. Greg just called me and gave me measuremnts of his pulley 1 inch and 3/4...and his belt is 1 inch and 5/8.
I'm happy someone changed my pulley and belt and tire prior to my purchase, becasue i have more room between belt and tire than do those who add 140 to stock belt and pulley.
stock belt in 99 was overkill for 1340 engine compared to new bikes that have 3/4 inch belt and pulling 180 tires or better.
i'll get photos tomorrow and try to include small ruler to show space between belt and tire.
is this the never ending story???
we are all learning and sharing info .

HI TIM,
 I see you have a 1" belt with the rubber flap and a small amount of space near the wheel. My question is if the rubber flap was removed will a 1 1/8" belt work? I ordered a S&S high strength belt and pulley. I tried to find a 1 1/16" belt and pulley but found
20mm , 7/8" , 1" 1 1/8" narrower belts. S&S did not make a 1 1/16" belt. Great Article!
Thanks,
Ltank

Just so you know in the photo above that is actually a OEM HD BELT which came on the 1999 FXR2 and it was the 133T 1 1/2" WIDE BELT!!!!

The NARROWER belt that you are talking about is actually the 1 1/8" WIDE BELT, for this year and for this model the OEM STANDARD belt width is actually 1 1/2" Wide.  IF YOU CHOOSE to desire to run a 1 1/8" NARROWER belt you have to select a 1 1/8" WIDE REAR SPROCKET to work with that size belt.  There is no requirement to change the Transmission Sprocket/Pulley regardless of whether you choose to run a 1 1/2" NORMAL WIDTH belt or a 1 1/8" NARROWER Belt.

In the above photo you also noticed that with that particular tire I chose to run I was indeed using the rubber deflector "flap" which attaches to the belt deflector guard.  Since that photo was taken I began running a 143 MM AVON VENMUM tire which was a bit wider than even that tire shows and had to remove a "PORTION" of the rubber belt deflector "flap" guard to the the point where the tire and the belt deflector rubber "flap" piece were touching....I cut that rubber deflector "flap" piece at a angle back to one rivet location, if that makes sense and was able to still use the rest of the attached rubber deflector "flap" guard and leave it attached to the belt deflector guard.

Based upon the engine size you are running I certainly would question the merits of going much narrower than a 1 1/8" wide belt.  

Perhaps my photo confused you, if you go back through this entire discussion the guys were discussing the merits of using a 1 1/8" belt vs the standard OEM width of 1 1/2" wide belt.  It just may appear in the photo that my belt is only 1" wide but that is the misgivings of the illusion of photography.  HD is running many of the later bikes now with 1 1/8" wide belts vs the 1 1/2" width they typically ran with back in 1999.  

ltank, if things like this get confusing, sometimes just going back to a HD dealer and asking for certain part numbers and asking additional questions will clarify certain specifics that you might need which might prove helpful to you.

Anyway I know this will clear up your confusion.

To further clarify, photos in posts # 14, #19 and #23 above in this THREAD show references to the narrower belt and rear sprocket size as well. All of these photos are showing the 1 1/8" application belt size while the photo in post #23 shows the 1 1/8" rear sprocket as well which accommodates the 1 1/8" belt.  Of course there are various styles of rear sprockets for a 1 1/8" application, the one depicted in this photo is a THUNDERSTAR styled billet styled 1 1/8" NARROWER Rear Sprocket.

Also given that I just did a modification to gearing in May of 2012 which there is a photo tutorial of that project also located within this website (mentioned for those of you reading this thread years from now) I replaced my OEM 1 1/2"  65T Rear Sprocket with a HD OEM 70T 1 1/2" Rear Sprocket given that I knew I would never venture to install anything wider than a 140MM Advertised Rear Tire.  I just decided for my personal preferences not to ever go beyond the 140 Advertised Width for a tire, if I had, the time to make such a decision would have been at the point of the gear change modification.

Tim

My rear tire is closer to the right side of the rear fender. As if the tire is not centered and thee 150 will rub
Did you center the tire? But doing so would place the pulley to far to the left? What am I missing?

[ltank]

Hi Tim,
 On my FXR4 my tire has less clearance on the right side between the tire and the inside of the fender. I  am using the stock wheel, brake calipers and axle/spacers (3/4").
Using my fingers as a guage the differance is very evident. The local bike shop owner has two peronal 89 and 93 FXR the fender appear to have equal clearance on each side.
Is my frame bent? I have never dropped my bike and there is no evidence of being dropped. Bike rides true with the old and the new front end.
I bought it used with 4100 miles in 2008. Now has 42,000 miles.
 I already have the 1.125" (1 1/8") belt and pulley installed on bike (68 tooth). My biggest issue will be centering the wheel in fender and correcting the axle spacers. My brake caliper is against the swing arm where it should be but to move the tire and brake to the left would require a extra spacer between the brake caliper and the swingarm and reducing the spacer width on the pulley side. Any suggestions or comments?Help? Was the bike tire in the article centered in the fender?
Thanks,
Ltank
