Hello, I have a brand new 80cc motorized bike. I only had her running for 5 days and I'm already having problems (some of which i created).
First one being that my bike was stalling out and i have to keep the engine well revved up so it can stay alive. At one point I just couldn't get it to start and i took off the cylinder head and I looked at it and saw a massive crack in the cylinder head. keep in mind I probably only have about 10-15 miles on this bike and I used a 16:1 oil/gas mix. I'm assuming that its just a defective head. I plan on ordering a new performance head even though the engine isn't all the way broken in yet.
Second problem (and this is definitely my fault) is that the rear wheel is now wobbly. I took out EVERYTHING in the wheel hub just to get the sprocket on because the rear break arm was in the way and I had to remove that. When I put everything back together I may or may not have over tighten the bearings and they may or may not have started eating each other.
Other than those 2 problems i had everything else seems to be working out great and I love the hobby. I knew going into this hobby that it wasn't gonna be the easiest hobby in the world and I knew that these bikes NEED HIGH MAINTENANCE. Hopefully I can get everything working and running in the next few weeks (still waiting to get paid to order the parts) and to get right back to riding.
