power loss

[wjamk]

when my 47cc is wide open and reving to the max it wants to bog down like it is wanting more fuel. I tried to adjust the needle on all the setting but no differance, we also removved the fuel filter and no diff. Can some one help me with my problem.

This happened on my 47cc and the problem was the carburater was loose on one side. I suggest taking apart the air filter, carb, and intake manifold. then just put them back together tight if nothings wrong.

I had the same problem on my modded bike. I swapped the carb and no probs.
Don't try to over jet the carb. If you do you will lose all bottom end.
as stated it sounds like it's sucking air from somewhere just re tighten and re check everything you should be fine.
