Welcome to the best motored bike forumHello everyone! I don't know what kit to get. I have a Trek 4300 and live in the mountains. I need something thats not going to poop out on me going up the hills. Any suggestions on what I need to get
The Chinese 2 stroke kits are NOT the only choice available.....I'll go with Bikeguy Joe on this one. After engine break in, if you still need more climbing power, you can consider a shift kit.
