Stroke stays the same as stock. Bore is the same as the V9 but with forged pistons. It’s the best of both worlds to be honest.So is 80x74 for the V7 and
84x77 for the V9 correct?
Is the V85tt and this new motor for the V7 also 84x77?
An oversquare engine explains the rev's and I see from your explaination where they got the power.
What is the bore and stroke of the 820cc kit you offer for the V7?
