Yes. The application of a proper pipe on a two-stroke motor is critical. The 250 pipe has way to much volume and not enough back pressure to allow the 125 motor to breath properly.Also check the ignition timing carb jetting and power valve for proper working order per Honda specifications.,

I just put a new fmf fatty pipe and a power core 2 silencer on my bike (1994 yz 250) and now when I start my bike it will run for like 10 sec and then It will bog down and die on me. Then it wont start,...

if the bike was running fine before you replaced pipe,you may need larger jets,or richen fuel mix,also check the reed valve it may be on the weak side.try a new spark plug also if you have not already replaced it.

Cr 125 02 wont start.makes wooosh/bang noise

you may want to check your card settings and the compression itself as the woosh and the bang noise means that the gas is burning, but not completely combusting.

hope this helps.

98 cr 125 has spark and gas but wont start.

When you rebuil the top end and pulled the power valve off did you put the screws bacvk in to the valve arm before puting the case and top end on cause you will either be closed or wide open on valve.and did you put the reeds back in? and make sure the floats are right and all jets are back in it the right way. try that
