Rm125 problems


Recommended Posts

My younger brother bought a 1991 Suzuki rm125 a couple of days ago. It ran fine at the guys house it had power and the power band would kick right in. Now that we have it at my house te power band Won't kick in and it bogs the whole time. It's that a big elevation difference from where it was to where it is now so I know it's not the jetting. Any ideas of what it could be?

Dirt in the carb. Bad top end, it could be starting to sieze. Dirty airfilter, tooooo much oil in with the gas, fouling plug.

Rule of thumb is: When ever buying a used 2T you should always do a topend rebuild before really riding it. This way you can inspect the overall interior condition of a bike before doing any major damge.

Good luck.
