Re: motor kit suggestions
Man, I agree with everyone.
Start simple. Get a decent bike, put a simple 2 stroke kit on it (without a jack-shaft , or what they call a shift kit). Then after a few months of tinkering and upgrading, you can get a better bike with a shift kit. Or keep that bike the way it is, and get a 4 Japanese 4 stroke.
But, do a search on this forum. Because this topic has been discussed about once a week. I'm sure you'll find all the answers you need in one of these topics.
