Why do Suzuki RM100 dirt bikes bog down?

Answer 1

1) The spark plug/plug wire or cap/coil are failing.

2) Your hi speed jet is clogged, or float isn't functioning all the way

3) The cdi/points depending on bike type needs replaced

Trouble shoot these one at a time and you'll get there.

Answer 2

i have one of these. It's a 2003. Mine is fine. Your carbureator could be dirty or you air filter, it could be a lot of things. it's not all of thrm though!!
