I'm getting my build dialed in, all the specs are in the sig below. I currently have 640G cams in the build (long story, not my choice) and it is making around 114hp and 100TQ

I am having the cams swapped to S&S 570 that I originally wanted and I'm assuming those numbers will swap, not exactly but a more TQ and less HP which is what I want.

Basically, will the SE clutch spring be enough with the stock clutch to handle this setup or will I need to look into something beefier?

 

If you have time to wade through 91 pages of this thread - there are countless bikes running that much and more HP on stock clutches with no issues

 

Haha, I'll take your word for it. I'm gonna throw the SE spring in there and call it good, if I start slipping down the road I will address the issue then

 

Good choice - I'm om page 73 but as I said there are lots of the Fuel Moto builds running similar numbers on stock clutches and one they are testing with somewhere between 140-150HP (forget which) that is also stock with no issues.

 

Im not saying I have that much power but Im running the Barnett HD spring and it grabs fine.
