( to be precise 0.9mm too deep).
to remedy this, i bought a packet of 5mm shims from HPI ( get the ones which are ID5mm, OD6mm)
i started adding shims between the clutch nut ( ho704) and the closest bearing till the clutch was freely spinning. i eventually added the whole pack of 10x 0.1mm thick shims ( that would make it a 0.9 mm depth i had to shim up).
if your clutch bell is sticking to the clutch when you push it in, like mine.
go get the shims and add it on, otherwise your clutch may overheat and break during hard racing.
i'm seriously surprised that there is no instruction in the manual about this part of clutchbell shimming. only about clutch gap shimming ( its not the same!)
i guess thats why Mugen makes pro cars.... we gotta figure the car out ourselves....hyucks
