Call and talk to Jason at Weller Racing. I'm sure he'll give you the scoop.

Welcome! How did you burn your clutch so soon? Dealer?

I think TEAM is working on one and their stuff is very good.

Supreme makes one with a lot of big claims, but I have not heard of anyone who has used it. I believe that you need to buy the drive and driven to make the Supreme one work.

What happened to your stock clutch or why do you want to change it? Perhaps we can help you here.

Clutch has not burned, just looking for more direct power to the wheels.

I heard EPI clutch kits work good and reasonable in price.

I called Mike @ Weller out of curiosity; I’m always interested in these claims. I asked him how you get more WHP out of after market clutches, to explain to me how you improve the casted clutch mating surface to rubber belt interface and coefficient of friction since that is really what we are talkin bout, to produce more WHP? By modifying the weights and springs he said? He could not answer me on exactly how that occurs, he told me to call airdam who is hard to get a hold of. Like to see what the explanation is not a ton of subjective theory no one can explain or tons of dyno results that are meaningless. When you get a decent response bring it out here, and as Bajaxp said we may be able to help weed through it.

I guess there is always the possibility of improving shift rates and belt side loads with different springs and weights, but adding more side load is not all there is to required friction. The stock assembly should do that for stock motor, if you have modified the CHP and want to get more WHP then it becomes of matter of trial and error on the specific mods, TQ/HP curves, not a cookie cutter solution for everyone, and I would really challenge the bang for the buck can’t be much. With more side load from CHP I can see a need for a billet clutch of thicker casted one, bigger weights and springs, and a better belt for reliability, but the heavier assy will produce a reduction in WHP.

It is about power band, riding style, altitude, and shift points! I talked to him and he had all the answers and didn't just quote numbers to me

Thanks I appreciate all the imput, I'll give him a call. Thanks again.

Thanks, make sense, all of you have been a great help with great leads.
