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? 

Regards,

Tim

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

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?

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)

Tim

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

Simply another view.....you can more easily see the "mud flap"

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
