big bore kit for rm 85?

[terrible]

Do they still make the 100+ cc kits for the 80-85 cc bikes? I remember them being a big deal back in the mid 90's. This would be for my 2004 rm85

Give Eric Gore a call at 630-825-5645, I think he can set you up.

What's the average cost of one? I'm just shopping right now and I don't want to waste some ones time buy calling them.

Try lukesracing , it should be around 350-500. Its a 99.4 kit but you can get ported and non-ported.

you can go above 100. 105 to 110 is about the reliable limit. you can very inexpensively go to 92 for a decent gain with minimal cost. when you do the big bore you run in to clearance issues with the power valve. If your going to do the work yourself the 92 is easiest. just ship your cylinder off to US chrome and have them do the .080 over setup. much improvement in power. Many different combo's above that of bore/stroke depending on what you want and what your willing to spend.
