This sounds like water condensation. Drain the carbs and a cup of gas from the tank and see if that solves the problem. If no joy, check the filter screen (inside the gas tank) mounted on the gas valve. A plugged screen may not let the gas flow freely to keep up at higher speeds. If still no joy, clean the carbs.

2003 yz 250 starts and idles but runs rich and bogs as soon as the throttle is applied


Hi, Anonymous and the usual suspects are:
1. Throttle cables misaligned or misrouted.
2. Damaged or restricted fuel tank venting system.
3. Intake system air leak.
4. Vacuum piston malfunction.
5. Accelerator pump leaking or no output.
6. Plugged bowl vent or overflow.
7. Fuel level in bowl too low.
8. Restricted fuel supply passages.
9. Plugged jets or passages.
10. Worn or damaged needle or needle jet.
11. The enrichner valve not seated or leaking.

2004 klx 125l starts fine, idles fine. Bogs down or hesitates at half to full throttle. Checked fuel filter and air filter. Bike ran fine for years and just started this.


Sounds like the exhaust is clogged with carbon.Remove the silencer and dismantle it if you can and clean the pipe and baffles.This should help you.

The atv starts with the choke on and idles great. When i go to throttle it bogs down and shuts off with an ocasional small backfire


you need to clean out the carburetor, the gas isn't getting through it. the bogging is caused by all the gas going into the engine cause of the choke, it dumps raw fuel into the engine and cant burn it all, there fore bogging and acting sluggish, the back firing is caused by the same thing, too much fuel going into the engine and being deposited in the pipe and igniting occasionally, clean the carb out and it will run fine
