hi Dylan are you still use HP4 now?
and did you try to put the standard flywheel?
or sill very noise? or sounds good?
Use a cosa clutch aswell or if you already are put stronger springs in too.[H]
Nice wheelies possible with HP4 ! ;D
The HP4 is a very good flywheel, the quality is great, the acceleration is superb, but on a high end tuned engine you will get some trouble with the clutch. Sometimes the clutch will exploding. You could solve the problem with a reinforced clutch basket! The flywheel makes the gap between the 3rd and the 4th smaller!

According to sip the hp4 flywheel is 2000grammes lighter than the standard flywheel.
This means that you will get higher rpm`s when changing through the gears, in effect its giving the engine a tune.[[:O]]
