Hey guys!
My 350K4 racebike has on dyno 30Bhp. I want to build a second engine, headwork, open carbs and exhaust like the first one. But i have an NOS Rocky piston kit with 67mm diameter which i want to install.
This pistons are 10gram heavier than the original pistons, could that be a problem for the crankshaft?

What do you think, how many more bhp?

Greets and thanks!

Andy

I thought the 350 is supposed to put out 36 hp? At least that's what it says in my K0 manual.. I do not know if this is at the crank or the rear tyre though..

Real world figures seldom match the published numbers in the FSM. Horsepower readings will also vary from one dyno to the next.

^^^and if it is 36 HP, it would be at the crankshaft - probably closer to half that at the rear wheel
