Re: Thicker gear shim ?

If youre within lower tolerance it could well be the gearbox worn on inner face, hence the rattle? Found this in my Gp 200 with 58k on. Unfortunately parts do where out

Re: GT200, What exhaust

The gori race 50 seems to perform well on Gt186 kits, 18.95 hp 14.35 tq, the Gp50 pipe certainly brings the kit to life 21.44 hp 16.73 tq which is more like an expansion.

Re: Longstroke quattrini

Gearing will depend on pipe used and crank id probably go pinasco.
My m8 ended up using pinasco case and mhr after breaking two casings
To get best from it you need a mate with dyno
