Hello everbody,
I am new to the world of bike engines. Have been working on my 80cc mountain bike project for 2 days now. Chain still falling off, had to move all bike cables from under gas tank to sides of bar and reset and trim all cables. Have not yet experienced the first test ride due to chain problems. I was exicited to get the kit, but now am starting to get a bit frustrated...

Are your sprocket's lined up ? Is the tension in the chain correct ?
You should have at least 1/2 inch of play in the chain.
Have any question's just ask, alway's someone here to help out.
When you get everything just right, you will really enjoy your motorized bicycle. I think most of us had trouble when we first started out...it get's better.
Most of us had to remove a couple of links from the chain to make it fit. They send a little extra usually so you have enough. If that is the case and the chain won't get tight you need to just remove a couple of links then reinstall the master link.
When you install the master link make sure the clip is facing toward you not toward the r motor. If you need to remove chain there are a couple of threads to explain it. If you can't figure it out ask and someone will explain.
Hi.. Welcome.. And.. For starters... There is no 80cc...
There is no such thing as an 80cc kit. The largest produced is a 70cc. If you bought from someone that says they are selling an 80cc kit, then.. Beware... As for your install. Do you have any pictures you can post? This would help us help you if you have any pics. Thanks.. Enjoy the ride...
Look down the top run of the chain from the rear...do the sprockets line up?
Is the wheel straight?
3/4" of play in your chain at the loosest part?
Tensioner running straight with the bottom chain run?

Welcome to the forum. Like everyone else has said. Check your alignment. Make sure it's really straight. Motorized bicycles are blast once you get all the bugs worked out. Glad you joined us.........................

I too am new too motorized bikes... One thing I quickly realized is not everything goes the way as planned. Be patient, give it time. Take your time building and fixing the bike, that way you learn more about how things work.
