I had the same problem when i put the clutch mod in my bike with heavy duty springs. I played with the spring combination some, still didnt fix it. I finally took the clutch mod out and put stock springs back in it, and my clutch went back to normal and my 60s went back to where they were suppose to be. Dont know if that will work for yours, but i certainly worked for mine.:2thumbs: I almost forgot, I ended up putting a hole new clutch basket in my bike also, and thats when the problem was solved.I installed a set of heavy clutch springs with stock clutches and my clutches are wearing quicker and my
60' times are worst than before. Can anyone shed some light on this. I have only a brocks clutch mod on a stock motor 08 Busa now with heavy springs?
The ones I have are stock from Gen II, If I put the Gen I spring towers can I use the heavy springs? The heavy springs I was using are for the Gen II and they are longer than Gen I springs.Do you have the long or short bolt towers on the clutch mod. The gen2 has long towers stock and the hd springs are usually for the short 1st gen style towers. I had the same problem on my 08, i had a clutch mod, then put hd springs in and it was crap, then put the short gen 1 bolt towers on and problem solved. i can almost guarntee this is your problem, measure you spring towers and let me know what length they are if your not sure, i have a set of 1st gen ones sitting here i can measure to compare.
