    200x piston in a 200s?

    Have the engine out of my 200s and im re doing the whole bike. Was wondering what piston to use to give me more power. Would a 200x piston work and make it have more power?

    See what compression and size it is ( the x ). As long as it's 65mm you should be good as far as fit. All I've seen is 10.25:1 on ebay as far as bumping up. Not sure what the stock is 8 or 9 something to 1. Don't want to go too high, unless you plan on working out your pulling arm a lot.

    A 200x piston is a Direct fit and will bump you up to 9.2:1 on the compression
