    I have a clutch problem since I had the upgrade to a 103 with cams installed. I have adjusted the clutch and the shop has done the same but it slips. I can run down the highway about 65 or 70 and hit the gas and it silps. Have been thinking about installing a (AIM)Variable Pressure Clutch. Ant thoughts yea or nay. Most people I have talked with say its the only way to go.

    DHDon, thats the setup I have been looking at. I thought about going with this system Stage 2.(Parts#VP017-340) Just in case I upgrade again.
    What ya think?
    Thanks for the reply

    I don't have experience with either system. I have read several articles on the AIM system and it seems to do everything the manuf. claims. I would ask what is the problem with your OEM unit. I know that it has been adjusted a couple of times and still slips when you hit the throttle. Have you inspected the friction and steel plates? Are the friction plates worn to a point that they need replacement? Are the steel plates warped? I understand that you have a 103 with cams but the OEM unit should have no problems with the added torque. There are several clutch systems out there that will hold some wild torque #'s. I would first want to know why the Harley clutch is slipping before I throw $$ at the problem.

    When they installed the 103, they also installed the SE spring in the clutch, about a month after that I noticed it would slip under hard throttle. With just normal to mild hard throttle its is fine. The hotter the weather the more it would slip. I have been useing Formula+ oil. So I thought when the weather ges colder I would put in the VCP. Should only that me less than a hour at my speed. LOL

    Check out the clutch wiz easy install and if you already have the heavy spring it would work fine. It is also cheaper I have tried both and my vote is for the wiz. tGLIDE Stuff.com

    I don't think this is what I am looking for. The pull is no problem.
    The problem is the clutch is sipping at higher RMP.

    That is just an added feature with the clutch wiz. as long as you have a heavy spring you should be all right I know some people with built 120 running them. Give Dennis a call and talk to him. Also MOCO has their own version of the aim clutch out. I still like the wiz.
