So I just picked up an 04 rm125 and it bogs and backfires like its overloaded and won't rev very high
It was rebuilt top to bottom when I got it
So far I rebuilt the carb, put a new plug in, cleaned and oiled air filter, changed oil, checked reeds, and checked all over for air leaks and found nothing. Do you think it needs a smaller jet maybe or what?
Thanks

What's your plug look like after you ride it? I had an 03 rm125 myself years ago and it was jetted extremely rich from factory, I was running a 460 main in mine.
