[QUOTE="EricGorr, post: 172696, member: 19611"] Holeshot, Wiseco offers 12.5:1 and 13.5 for compression ratios on their line of big bore pistons. For any of you guys with older 400s looking to upgrade your bikes in the face of this recession, consider this, the stock connecting rod has been improved and the small end pin increased 2mm in diameter. The cylinder is also thicker to allow for overbores. I suggest starting with a 426 rod kit and cylinder. Those parts are dirt cheap, if you want to go the extra mile the cylinder can be overbored and plated like Bill's to 97mm. [/QUOTE]
