big bore options

Recommended Posts

I know that athena make a big bore option, but the price tag is rather steep. Does anyone make a do it yourself kit? Sleeve piston etc that works good. I can get quality machine work for free, so if a sleeve kit is available, I would be very interested.

Thanks

What year is your bike and what size BB are you looking for?

Its an 06 & somewhere around 280 or so, but I would also like good reliability. I don't race, but in certain situations the added grunt of extra ccs would be nice.
