Largest Bore for stock 88 cylinder?

[stever250r]

Dont bash me... I didnt feel like digging through the search results..

I am getting ready to start tearing into the engine on the 88 model... The 88 cylinder I have seems to measure out at 67.50mm. Is this too large to use an 88 style piston? I do not want to use the 86 style piston and spacer plate on the 88... I want to go back stock...

What is the largest bore I can have and still use the 88 crank/rod, and the 88 stylel piston with no spacer plate?

looks like wossner lists a 67.94, so Id say you could take your cylinder out to 68mm with 87-89 style piston, I didnt check on any other brands

Wiseco book lists up to (and including) 68.00 mm pistons for the 87-89
