84 125m - Over Bore & Crank?

[DasUberKraut]

Just a quick question...

What's the most a 125 motor can be bored over?

Also does anyone offer a better crankshaft? Will valves need to be modified as well?

Thanks in advance.

ive got a brand new +2 mm rocky piston kit for the 125m for $65 shipped if you want, this is the biggest kit ive seen for the 125m

I may take you up on that. I was looking over ebay and seen that the 56mm is the biggest.
Does that kit inclue the rings too?
