1998 rm125 running problem - Motorcycle-Journal Forums

qwicksilver17 · 03-11-2004, 12:30 PM

Hey, i have a 1998 rm 125, bought it second hand the other week. It ran great for a couple days but i get it down to our farm and it cranked right up, ran for 30 seconds then like bogged downand would not start. I took out the plug and it looked like it had been dipped in oil. so i clean it off and itll fire back up but does the same thing..
we took apart the carb and it was spotless...so we had no idea what else to do..

i took it to a shop and the guy ther said all he can see wrong is the reed valves are weak and could be lettin in too much gas. my new reeds arent in yet but im wonderin, how hard is it to change them?? i mean that guy is one of those, im not gonna charge you if i cant get that bike runnin, so i figured id just change them. has anyone else had similar problems???

what is your pre-mix ratio? the new reeds wil probably help. you might try running a plug with a hotter heat range.

If it only does it when it's hot it maybe a bad coil. I have had that happen on cars as well as bikes.

How do you tell if the reeds are weak?

The edges will be frayed or the corners will be cracked/broken off.
