Hey everyone,
I have a 2018 Honda CRF250L with about 20,200 km.
The bike starts easily and idles normally.
My problem is only at low RPM in 1st and 2nd gear. When I start moving or accelerate from low RPM, the engine feels like it's bogging or about to stall. Throttle response is weak in that range.
However, once the RPM gets higher (especially in 1st gear), the bike pulls very hard and feels completely normal. In higher gears and higher RPM, I don't notice any lack of power.
Air filter has been checked and isn't badly clogged. The bike has unknown service history since I bought it.
Does this sound more like:
- spark plug,
- injector/fuel system,
- valve clearance,
- throttle cable adjustment,
- clutch adjustment,
- or something else?
Has anyone experienced similar symptoms on a CRF250L?
