I see that the manual says to remove one compression ring to reduce friction.
Like the 1 ring pistons on 2 stroke machines.
This modification increase the oil burning, does any one know how much?
Is OK for road bike? (I want to made this modification)
Is for the stock Kawasaki pistons or for special ones?.
