I need a little input on clutches, I just put a little more HP in my engine, now my clutch is slipping when I hit a high rpm.
Need to know what kind of clutches & springs to put in.

 

Barnett lockup

 

Primo-Rivera makes a killer clutch

 

Barnetts will be my choice when its time !!!

 

Are you sure you need a new clutch? Have you fully adjusted the clutch properly? If yer not runnin in excess of 100hp, then you really shouldn't need a new clutch. That is, IF yours isn't worn. There are a few threads on this subject, with good instructions on proper clutch adjustment. Might give that a shot first. Unless you just need something other than the extra hp you added to brag about...
(That wasn't a dig, many people buy simply for bragging rights.)

 

Yup, try a bigger spring in this case,if the adjustment does not work.Another thought, are you using synthetic oil in the primary?

 

+1 I'm over 100hp and updated the spring with satisfactory results (no slippage). Easy and cheap (like my first GF) fix for a street bike. If you're a regular at the track, well Barnetts....

 

Already tried ajusting Harley tech blamed it on the ez clutch on the bike has 50k on it just needing new clutches

 

Try heavier spring, or add the VPC to it!!!!
