Was very concerned about clutch slippage and clutch life on the Frontier.

With 140 ft. lbs. of torque @ 3000 and 130 @ 2500 the Frontier was a prime candidate for slippage.

Enter the VP 92 T lock out clutch from AIM.

Installed yesterday and no more concerns!

Honestly Brian NO
Maybe 35 miles on it after installation yesterday but based on my CC's rep and the infamous DAWG, I'm thinking I will like it.
Will let you know after a few more miles.

Brian,

The only concern you may have is that you may have to dremel the derby cover back side, a bit so that you have clearances there from your 04 derby cover its a must check thing. There were a few posts about it just cant remember where I read it.

Curious how the clutchplates will hold up with all the power even with the lockout. Wondering if going with the Pro Clutch and the VPC is the right combination. We will have to see how long Chips clutch plates hold up to the normal wear and tear they are going to get ...

Those who may have need for the VPC units in United States can get them from a fellow named (Hippo) Frank, some of you may already know him. His contact info is HippoVPC@gmail.com.

He probalby has the most experience with the VPCs around except for Yasu Watanbi, who is with AIM, the manufacturer.

Oh, by the way I sell the VPC in Canada.

I tried to attach an article by Hot Rod Bike of an install they did of a VPC unit forgot what model, however, the attachment was to large.

If anyone wants a copy PM and supply your email information and I will get you a copy.

I will try attaching a picture of the VP 92T.

I had 6000 miles on one with my last Ultra (non SE). No problem at all. Easy and quick to fit, worked great at reducing the effort required at the lever. Sometimes a slightly "strange" feel when you pull the lever in, almost a sort of click being felt through the cable. But that wasn't a problem. On the whole it was excellent, but here in Europe they are a little expensive. I probably wouldn't buy another, because of that, because it's not actually something I need, just "nice to have".

Basically it has pivoting weights on it. As it rotates, centifugal force moves the extra weight onto pushing the clutch plates together harder, so it's less likely to slip. The main advantage for people for whom clutch slip is not an issue is that it reduces the effort required to pull in the clutch lever.

Jim

DCFIREMANN · « **Reply #20 on:** February 25, 2007, 08:44:43 AM »

I never noticed it being any easier to pull the clutch in, but I can tell you with a 130 H/P 113 ci motor it doesn't slip. AT ALL!

As a matter of fact when it hooks up it will pull the front end off the ground in 2nd gear a good amount. It suprised me and the bunch at Ghost Town HD. They were standing out front watching "V" take off on the V Rod with her Thunder Header. It took a little distance but I did run her down. Even she was suprised how far the front end came up. All I could say was ME TOOOOO!

So all in all I can sya ZIPPERS HOOKED ME UP!!!!!! lol

Chip when you get some miles on it let me know. I am sure it will hold, not too sure about the belt though. NO HOLE SHOTS!!!!!!!

I think I saw a version of it yesterday on my buds drag bike. Little floppy things were attached to the external primary drive, and he said they needed to be carefully weighed to allow centrifical to take over. More weight, faster lockup. Is this the same thinking on the vp2?

Now a silly question. When the clutch lever is released, doesn't it lock it too? And allow slippage when engaging smoothly? I can't imagine an imediate lockup every time. Doesn't that put quite a strian on a variety of components that way? Thanks in advance, just trying to learn wazzup in this arena.

I had heard it was suppose to be easier to pull in the clutch in but mine seems to be the same. It's very easy to start with.

I'm running a 135 tooth Gates belt as stock.

Guys and Gals,

Out of curiousity where are you purchasing you VPCs from?

They also make them for the EVO and Sporsters.

I tried to attach an article from Hot Rod Bike on some information and installation of the VPC however the file was to large.

If you want email at harleyshewchuk@aol.com and I will send it to you.

SILVER-BLACK (not yelling just trying to get your attention)

From the color of your VPC unit you do not have the VP92T (used for 120" & 124" engines), you are running the VP83T (used for 103" Stroker Engine) as it is blue and the VP92 is a Red Color.

See attached picture.

The VPC unit is great. Bought mine from Hippo. As Geezer mentioned, he knows more about HD's than most people combined. I don't think the VPC by itself makes the pull any easier. On my 106" motor, I combined the White Bro's easy pull clutch kit, the SE clutch spring, and the VPC83T. Works great, pull is light, and I could NOT make it slip.

Definitely does, GC-Soop! One of its main selling points, in fact. Reduces lever effort by up to 40% (the VP67T is the one used for that benchmark), since it changes the points at which the pressure on the diaphragm is applied, giving more leverage.

I've had a VPC on since day 1. It does decrease the lever pull and broadens the narrow engagement point of the stock hydraulic clutch in addition to it's other benefits. My clutch engagment was like an on/off switch on the ride home from the dealer. Maybe I was used to the VPC on my other bike, who knows. I installed the VPC the first night I had the bike home. Worthwhile in my opinion. I got mine from Hippo. Installation with a hydraulic clutch is a bit more difficult as there is no way to "loosen" the clutch cable. You had to finess the stainless base plate insert into place. Probably just easier to remove the primary cover as opposed to just the clutch inspection cover.

Thanks Harry, I saw the selection chart on their site. There appears to be 2 to choose from for my application, and wasn't sure which to use. The VP84T w/AM007-380(SE) or the VP92T w/AM-007340 both seem to be applicable. There are a lot of overlapping numbers on this chart and want to get the right one. Also, are there derby cover clearance issues on the '07's?

Howie,

Haven't tried it on the 07 yet, so I can't specifically tell you that it has an issue or not, but on the 04's it did take clearancing, but not much on my 02 and 03 that were not CVO there were no issues. But even if there an issue its fixed in 3 or 4 minutes with a dremel it is not a big deal really just a tiny bit of grinding on the back side of the derby cover, so in either case I wouldn't really get concerned by it.

We have tried them on several of our kits and no longer use them. We install the primo pro clutch and forget about clutch problems. Have the bike dynoed again and then you will know if you have slippage. Seat of the pants will not tell you the whole story. If you feel it slipping then it is bad, we where getting 2-3% slippage with the monster VPC, with ramps, heavy spring. And by that time the pull was heavy on the lever. The primo is more money but not by much after you use the previous parts, the lever pull on the Primo is very light and it will not slip. Same clutch pack is used in the open systems. I make 159/163 and there is no slipping. At the track I leave at 3800 in 2nd gear no issues. I have adjsted it a few times over the last two years. It does not wear like a stocker. A VPC works with RPM so you are still working with the small amount of disc surface, and cheap discs from HD. Not the deal with a Primo.

I have other customers who like them but one thing you have to look at is how the engine makes power, as you have many items that can effect how well it will work. They are working with rather mild builds.

We have plenty of customers try the heavy disc first them they will go to the VPC in the end I get a call as they are done messing with it and buy the primo. This is just my opinion , it is based on the amount of builds we do. Not bashing the VPC but I do not think it is the end all be all. I have removed two many of them for slippage, some was after getting a few thousands miles on the set up. Riding style is going to play a role here as well.

Talon · « **Reply #53 on:** July 01, 2007, 10:06:53 PM »

This type of setup has been used in cars for some time, basically allows lighter spring pressure, or in some cases a smaller lighter clutch, the weighted cams kick in as the rmp's increase the pressure on the clutch pack. Works well in cars, I have never tried this unit, but am planning on using it once I get a little more HP in my bike.

Hey gang, Hippo responded to the email. This is his email address. hippovpc@gmail.com He is still getting these VPC's. I ordered the VP92T for '07 SERK, 274.20 delivered. There appears to be no discount available, so I just ordered one anyway. For my build, he suggested using the SE spring, which is stock on the '07 SE's. According to the table, it's supposed to be 7% less clutch effort. I doubt you'll feel that, but as long as this thing keeps the clutch from slipping, I'll be happy.

I doubt you'll feel that, but as long as this thing keeps the clutch from slipping, I'll be happy. Hoist!

Howie,

You bring up a point, the clutch effort. I can understand that at idle, the clutch pull is reduced. Does the clutch effort increase as RPMs increase?

According to the table and curve that Harry posted above, it follows the same load curve as stock, just in the reduced or increased amount, based on the spring you use, and the values shown in the table for those springs. For my application it shows 7% less lever effort. That would follow the curve throughout the RPM range according to the info above, the best I can tell. Hoist!

I just checked out the table and found this little gem at the bottom:

(4) Clutch pull becomes heavier as RPM increases.

I wonder how much stiffer it becomes, say at 5,000 rpm?

Missed that, but I'm not expecting (hoping for) much change at all with the stock spring. Hoist!

I would think a 50% increase in clamping pressure would require a 50% increase in clutch effort. One is fighting the other, so I think it's got to work 1 to 1.

They do get very hard to pull in at high rpms. Try it and see what you think, I only posted my experiance with them. I think they fill a void but not for what we do.

Not trying to rain on your parade my man. We need you to try it out and report back to us that aren't running on the same curve as you. I've got time for you to find the way, then I can follow your lead.

Hoist! · « **Reply #63 on:** July 02, 2007, 10:56:05 AM »

Since I'm not going crazy with this build, I'm hoping, as Steve said, it fills a void. If it works as advertised, it'll be OK for my purposes. Next step would be a complete clutch replacement. I was hoping to wait until more things are available for the redesigned '07 setups before considering a clutch replacement. Until that time, I hope this does the trick! I'll let you know what I think of it. Hoist!

I guess a question to ask " is it a money issue??" if so try it if not buy the primo as it will work , it will provide less effort and it will not slip period

Well it isn't too expensive and doesn't require removing the whole clutch assembly and rebuilding it. Fairly easy install. Since you can only buy the clutch parts, and not an entire replacement clutch assembly, I wanted to wait and see what comes out for these '07's. I was looking at the King Kong Clutch, but Baker isn't sure what they're doing yet for '07's. If this thing works OK for now, I'll live with it. If it doesn't hold up to the power, or becomes too much effort, it'll be time to look at replacing the clutch. Hoist!

Well we have hd some that we could not get in through the derby cover so we still had to remove out primary cover, at that point you are about 1.5 hrs of labor to install the primo. If they are bought through us and customer does nto have access to a press we install it for free and ship it back

Thanks Steve. Something to keep in mind. I'll let you guys know how the VPC works out. If I don't like it, the Rivera might be next. I have the Pro Clutch in my other 2 bikes, and know that it would hold up fine, and it has less lever effort than stock. Hoist!

Chief

At 5000 rpm the Frontier generates 132 ft lbs of torque (same as it does at 2500).
At 5000 rpm the Frontier generates 125 horsepower. (I just checked the dyno sheet)
I have made many a shift at 5000 and never thought a second about it.
Does that answer any question about the rpm increase vrs the effort to pull in the clutch, I'm not sure.
One thing I am sure of is that ocassionally things are flogged to death about a potential problem when there really isn't one.
But what do I know?

Mine has worked great for the past 4500 miles and I'm happy with it!
That's the criteria for performance in my world!

And Hoist
I didn't use the 92 for a good reason. Call me later and I will explain!

Chip,

I just asked a question because I was curious. I'm sure its a great device as I have read great things about them in all of the rags that have installed them for tech articles.

Not under the pillow, it's the pillow case
Had pillow case's printed up with the dyno info printed on it.
Have Nancy's results printed on her pillow.

When we have a pillow fight it's all about horsepower!

No offense taken. I just wanted you to know I wasn't flogging the whirlygig just because I was asking a question about it.

Big Al · « **Reply #75 on:** July 04, 2007, 07:32:14 PM »

FWIW, I have had a VP92T for the last 2500 miles or so.

My FLHTCUSE (see what's in it below) was breaking the clutch lose at WOT and 4500+ revs (felt like a missed shift).

Now it locks up and goes! Even makes the front wheel light. No increase in clutch effort whatever...

Easy enough to put in that I did it myself- of course hd-dude checked on the next service...

(If the dealer ever takes the Primary off my warranty is toast what with the GP Bearing support and the VP92T

)

Best $200 I ever spent.

Anyone familiar with the install of these things on an '07? The instructions speak of a Cable actuated adjustable clutch. I have an ’07 SERK with the Hydraulic Clutch actuator. Also, there is no clutch adjustment on the ’07. So the first 2 items in the insructions are in question.

1. They say to back off on the clutch cable adjustment. Do I need to open the bleeder or do anything with the Hydraulic system to install this?
2. They say to adjust the clutch adjuster. Since there is none, I assume to just ignore this step.

Basically, I assume to ignore Steps 1 and 2, and just install it. What's with bending the tabs?

Is there anything else I need to know or do for an ’07 model?

I'd like to have all this straight in my mind before installing it. TIA for any help ya'll can provide.

Hoist!

I also have the hydraulic clutch so as you say "do nothing".

The tab bending is simple and I think helps to hold it in there while you snug up the new plate. The rotating pressure 'thingies' push up against each of those tabs to distribute the pressure...There was a previous thread on this somewhere which I can't find...

My key worry was that the VP92 wouldn't contact the inside of the Derby cover...I spent a lot of time measuring but actually for 06 there is no issue...I also went to Tak's site and while its mostly Japanese, there is a video there which is 'self' expalnatory...

Hope this helps..

Thanks Al! It does help.

I heard from Hippo yesterday and he also said to ignore the first 2 steps completely. Thanks for the clean copy of the instruction sheet too! Looks like a pretty simple installation. Hoist!
