[QUOTE="reepicheep, post: 1424662, member: 104942"] More power to you if you can find cheap parts.. but you don't want the stock KDX-220 piston, it is a grenade waiting to go off. So you want (and will be buying) a new Weisco anyway. And if you can find the stock 220 cylinder used, that's great also, but it is tungeston elctro diffussion or something... not terrible, but nowhere near as durable as something like nickisil. So you might have to re-bore that stock 220 jug. At which point, you are spending more than the 225 kit (send your stock top end to be bored and plated, get the Weisco and to end crank bearing and pins and circlips, and get the Weisco piston). Same as what you were doing, except you didn't have to buy the 220 cylinder, you rebored the one you already had. I think the whole deal was around $500, and that included head porting. I know that's a lot to put into a KDX these days, but its not just "turn a 25 hp motor into a 27 hp motor", it's a "build a motor you can run for several hundred hours without doing a thing to" motor. And the nicisil is probably a "life of the bike" plating. [/QUOTE]
