How much did you overbore the cylinder walls to get the 850cc?ScrewDrvr said:Bike is a 97 zx7r with a 850cc big bore kit, full exhaust, jetted. etc..etc, with all the supporting small mods.
Just wanted a questimate on what kinda rwhp and torque the bike will make now, also, what times should i expect at the 1/4?
I beleive the stock specs are like 101rwhp 50rwtq, and 11.2 @ 129 inthe 1/4? Is that right?

I've read that the engine only takes 1.5mm overbore while still being reliable. Some have apparently used 2mm overbore on racebikes though.Tiamat said:stock specs are 73mm x 44.7mm
just boring the cylinders to get to 850cc's would be a bore of 77.8mm, or almost 5mm over stock. not too sure they could take an overbore of that much.
