i finally put this on,it it flat out kick ***,i can't stop revving this thing,i'm near 60 g of weights and it engage at 5200 rpm with hpd blue
primary,this was only my first day of tuning,it is A LOT quicker than standard polaris clutch and it pull real hard through the range...
later......

 

Cool! Now that's with no other changes, other than changing the primary?

 

i just put together the same clutch setup,thundershift cam arm weights set at 54.5 g,with HPD blue primary spring,15.5 billet dome on race gas,
it was at first engaging at 5400 rpm (real strong hit),then i added some more weight to the low end (a lot to reach a total of over 60 g of weights) and retest,the engine then was lazier but still engage at 5100 rpm,
it is a lot quicker than any other best clutch setup in the old polaris primary,a 1000 rpm gains in speed and powerband,
i'll make the fine tuning soon,more to come....

 

hey what does those comet clutchs cost i think i would like to have one my self.

 

Pro, I'm really not sure who's carrying them...I got mine direct classified. [img]i/expressions/face-icon-small-happy.gif[/img] You can maybe check with HPD, Hot Seat, Aaen, or maybe someone will post where they got theirs. For clamping force on the belt, it can't be beat....plus some other benny's.

 

There was one on ebay really cheap!!!!!!

 

i think they really worth it,i got mine from a dealer wich make order
from motovan.com...also maybe royaldistributing.com has them by now,
those are canadian distributors..

 

Would the clutch be beneficial in drag racing on a trail ported 400 scrambler?

 

So I'm told, the drags is where it shines. Haven't personally experienced it yet, but sure sounds like Scramblered is having fun.

 

wouls it give a lower engagement of the sp700??
