I'll be getting my sons Lt back from getting modded here pretty soon and will let you know how it performs vs. stock. Getting all new rollers (drilled) with lightened rear clutch with some mild porting and shaved head with weisco piston. I'll post the results when done.

 

What would cause the rollers to melt down severely. And they only have maybe 5 hrs on them. I built this clutch the same as the last and never had this problem.

Also what's the difference between 4 rollers or 6 drilled? We never seem to have any luck only running 4 rollers.

 

I like the way 6 rollers drilled work. If I remember correct 6 stock rollers weigh about 58 grams 6 drilled about 47 grams and 4 39 grams so it’s all about weigh.

 

How do you drill them? Thanks!
