I had to make a special socket for the spark plug. I had about 20 of those cheap spark plug wrenches from predator motors but wrong size. So I bought some multi spark plug wrench from home Depot. After making a paper mold to see exactly how long it had to be to fit under the frame and under the gas tank bracket, I cut it down and works perfect.
My chains kept binding. I think it was a combination of 2 things. No clip on the master link front chain and the back chain had the master link facing the wrong way. Seems great when I roll the bike. No test ride yet. Lol.
