View Full Version : Jet problems with 125m, nned help



11-09-2002, 03:45 PM
I just bored my 125m .50 over, put a pipe on it and uni filter and new plug, it was running ok when I was braking it in but it had a fuel leak so I got a brand new stock carb from honda.

The problem I have now is that after changing the carb to the brand new one, the bike will not rev beyond 3/4 throttle. It runs great up to that point, then it falls flat on it's face and will not rev out any more. Is this a lean or rich condition?

Right now I have a 95 main jet, stock is 92. I changed to a 95 and it got a little better but not much.

Could it be anything else? I thought it could be a electrical problem but if I just wack the throttle at idle it will flop. If I throttle up slowly it will rev till about 3/4 throotle when it will die.

Thanks i advance
