I didn't know about being able to bore up to 140, thank you for that. I am hoping to be able to keep or get a cylinder as close to stock as possible. At least until I get the hang of this bike. Once I have it mastered while it's stock, then I'll start making modifications. Unless I can't get a stock one. Then I'll just deal with it! [img]i/expressions/face-icon-small-smile.gif[/img]

 

If you find a cylinder thats been bored a few times thats not going to make a trumendous differance in power. No matter how much its bored im sure you'll do just fine. If you have experience on a quad the only thing i can tell you is to hang on a little tighter. If you have any questions on your motor let me know cause ive gone through both my motors quite a few times. good luck!
