Hello! I have a cheapo 2 stroke motor on a cheap frame right now, and I'd love to spend a bit more for a nicer setup. I bought my bike for $150 total, so it's definitely nothing special. My spending a bit more is probably very cheap according to the usual standards, the most I wanna spend total is $500, but I'd love to spend around $300. The person I bought the bike from says that it has a maximum speed of 35 MPH, but I think I'm getting more like 25. I'd love to be able to cruise at 35 MPH, as that is the speed limit on my road, but be able to go up to 45 MPH for short highway travel. If anyone could point me to a good kit, frame, and tutorial for my budget that would be greatly appreciated. I've been working on my 2 stroke for about a year now, but I probably don't know very much about the engine. Most maintenance is tightening and putting stuff that falls off back on. The most complex issue I've had was needing a new clutch cable. EDIT: I forgot to include one crucial detail, I can only have up to 50cc, which is the legal maximum in Oklahoma.
