Im addicted

These two stroke China motors are very simply. If the engine has gas and spark, it runs. You will get the hang of it. Best bikes to use are steel framed hard tail mountain bikes or beach cruisers. A brand named bike like Nirve, Electra, Specialized, etc will last a long time. Walmart bikes will work but bearings will wear out sooner.
Yes, this hobby is addictive. My favorite part is that you can make parts like fender brackets from curtain rod brackets or other things you have laying around.

Good luck, Eric.

We'll be here when you need help/advice/opinion/support.

If you are willing to be patient with it you should consider rebuilding the happy time engine you got. There's a number of threads laying about. biknut has one for his T80 and recon chris has one for his GT5 motor. Same deal for both though. Don't forget that inch-pound torque wrench before you do! Gotta have it for the head nuts

If you don't want to rebuild it all (like balancing the cranks) you should atleast take the head and cylinder off to clean out any trash that may be inside. Then maybe port and polish (don't polish the intake) while you're at it? There's a sticky on it. I think in norm's area. File the fins of the cylinder so they look nice and purdy. Then maybe replace all the bolts in the motor with high grade steel ones. SBP has kits for it. Blue threadlock is a must for these motors too! Primarily on the studs and mounting bolts. I put some on my head bolts even since I noticed that they were not at the torque I once had them at.

Great thing about the cheap chinese motors is that they are so simple and in need of TLC you really feel that much more rewarded when it all comes together. They should be able to last a couple thousand miles given the proper care. Which in turn equals a couple years on such a tiny engine. Not bad if you ask me

Perfect! Filing the fins is just for cosmetics. Makes it look a bit more professional if someone takes a close look at the engine
