Big bore 66E or GP1300 cylinders (pair)
I'm putting a GP800 cylinder into a Superjet. I'm piling up parts and thinking a big bore would be cool. Let me know what you got and what you want for it. If it helps i have some very nice stock cylinders and pistons I can trade.

Pound for pound the 66E cylinders are going to give you more power most likely due to the significantly more extreme porting thats already on the cylinders.

I friend of mine just put together a wild 66E. It's been sleeved and runs 88mm bore. It has RIVA heads and he had to get custom domes made because the o-rings were right on the edged of the sleeves and it kept popping o-rings. It's all good now and with ~950cc it hits HARD.
I'm not looking to spend that much and would be happy with 84mm bore as that would put me about 865cc. But if I am going to pay for a bore and a re-coat and a new set of pistons, won't 87mm cost me the same $$?
This is just a spare time project, my main ski is a Rickter FS-1 with a 946cc 62T based Lamey/DASA motor that hits as hard as the 950cc 66E but weighs 30lbs less.

Talk To Lowell Horning @ 2-Stroke Porting.com (link in my signature) he has some already ported and ready to go.
