my engine leans!?


Discussion at Motorized Bicycle Engine Kit Forum in the Mounting Techniques forum. Ok guessing here could the extra spacers give way to warping the studs at the rear? Just thinking out loud ...

Ok guessing here could the extra spacers give way to warping the studs at the rear? Just thinking out loud here. I am wondering how you got the extra mount [ spacer]. Musta been the newer kit. If the studs are not a grade eight strength, plus 6mm is a small stud.Strength wise.

mycam,
It is a home made item fabricated from stainless steel. Not a muffler clamp but maybe the same concept in that it uses a 'U' bolt. The bushing is polyurethane not rubber and is very rigid. Sorry, no, I don't build them to sell.

When I first mounted my engine it would start to lean left while I was riding. I didn't think much of it, and when I was done riding I would put it back and tighten the bolts... This was until without warning it popped of a bolt and fell to the left, luckily onto my pedal and not the ground. I did a little unintentional acrobatics over the handlebars and had to carry the bike nearly a mile home(It wasn't even roll-able). I decided then to drill my frame. It holds rigid in the middle now and as a bonus I have noticed less vibration. Maybe drilling the frame and bolting through it could be the answer? I know it sounds as appealing as drilling a hole in your own head but if it is leaning dangerously it could be worth it. Hope this helps.

Nice pick up Tom. That is weired. How did he ge thte thing to fit. Either way with the motor being that far awat from the frame I would bet there would be a lot of flex/movement when the motor is running.

Get rid of the extra spacer on the back of the bike and I think that will solve your problem....

Is your muffler touching the frame on the left side?
