Where can I get one of these bushings, so I can have it ready before I even put the engine back together. I guess needle bearings are going to be out of the question since they are probably not going to fit. |

Contact the original seller of your engine kit and ask if they can get the parts you are looking for.
No, a bearing will not retrofit where the bushing is now.

Can needle bearings be used where bushings were, and will the bushings and bearings be the same on all of the 2 stroke engines? 50cc 70cc, and 80cc. If so is this the size? KT101412 Needle Bearing Cage K 10x14x12:Ball Bearings:VXB

Dax is out of the bushings, anyone know where I can get one. Seems like that is what is wrong with it. making that noise, kind of doing it as a maintenance thing. Make sure does not blow up. Heared it is the week link in the engine. Probably what is making that noise. |
