Hey guys,
I got the epi clutch kit in my clutches, orange primary spring with 50 gram weights,
Purple secondary spring, not sure on the angle on the helix that comes with the kit.
I got 20 top gear, 40 bottom gear in the chain case.
My issue is that Im only hitting 7000 rpm at wot.
Is there anything I can do in the clutching to raise it to around 8000 rpm?
