I tested the clutch cam and it seemed to work great, so I go to the track, first pass 6.52@112mph, it didnt wheelie at all, it wheelied big time when I checked it at home, but it was controlable, second pass my time went to 6.60 and I could feel the clutch slipping so I parked it, guess the slipping was why it felt kinda weak in power, I will pull the clutch and inspect tomorrow. this was my first time out on it, I should get some 6.30's next time.

If you do the clutch mod you definitely need HD springs or spacers. Make sure you put that last friction plate in correctly or they won't last long.
 
Call Brock's and get the correct 1-piece mod...

I had a bad clutch mod, I installed the 2 piece back in it with no slipping.

What did you change with the springs when you did your clutch mod. Springs? Spacers with OEM springs?

just added the clutch mod.

I think that is the problem. The stock hub acts like a lockup clutch. If change to a one piece hub you disable that function. That is the reason Brock puts .180" spacers in the package. You run them with stock springs to increase the plate pressure or run stiffer springs. The spring and stand off combo is also different then the GEN 1 bikes so the springs do not appear to interchange. I have not measured them but the part numbers are different.

I had the clutch mod on my 01 back then, no springs added. I like the oem clutch on my 14, and was hoping the Busa could keep the oem plates and springs.

Call Brock and confirm, but if you look at the stocker it changes the pressure on the plate under acceleration.
