What's the clutching? Stock? Weights? Spring colors?

 

[3xthetrouble]

stock yellow primary spring and the weights are 72gram I did have 76 gram in there first and it didn't do much.

Mines an 03 F7 snopro with the stock clutch setup yellow spring, it revs 7600-7900 at sea level.

what weight profile? YOu might be over weighted.. I had that issue. Put it lighter weights. Problem solved. And pulls hard
