I whacked a new Continental Conti GO 120/90 on the back.
Fouled on the chainguard but my wife fixed it.
Rides nicely and feels more firm on the bends.
Also, thanks for the compliments re the head work.
I'm an old bloke with around 35 years pure engine experience, mainly high performance eg. top fuel, blown alcohol, sprint cars, rally, Lycoming and Continental aviation engines, Bathurst 1000 etc.
We work on small engines these days like ride on mowers, chainsaws, RC motors.
BUT !! Now I have the Bullet to play with.
Bought a spare engine that head is going onto, with serious cams, Power Command V, bottom end balance, alloy con rod and a piston from a turbo Nissan engine
