    Ok Is the carby slide moving up and down remove the air tube off the carby (filter side) and look in the venturi or put a clean finger in side and move the throtle grip. If it dosnt check the cable, twist grip os carby slide.....

    If you remove the screw top (big) on the caby where the cable goes in lift it out carfuly dont damage the needle at the bottom...operat the twist and see if the slide moves. if it does remove the caby ,remove the jets and tubes and clean...

    when installing the slide there is a groove down the side of it, this MUST locate on the pin in side not on the idle screw...DONT force it in...

Sounds like a bit of trash plugging the main jet. This is not a major repair. Just pull the carb off and remove the float bowl. Clean the bowl then remove the main jet & blow it out. reasemble the carb then go riding. P.S. The main jet is a small brass fitting in the center of the carb. It screws into the body of the carb. A single drill hole runs through the jet.

I have a 125 pit bike and it ticks over fine but when you rev it it backfires does any body no how to fix it.

You can check ur values but some bike do make a we ticking from the values and it will back fire when revved up because of the extra fuel once revved that hasn't brine burn as it revs back down to idle speed.

Bike revs uncotrollaby. 125 yz 2002

Is the throtle cable stuck? if not look at a good carb clean, it could have enough gas to start but be too lean that would make it rev up. Two stokes also do this right before they run out of gas

How do I know when my clutch is going bad?

Clutch does not go bad. It just wears out. And the indication is that your bike will not accelerate as much as the throttle you apply. The engine keeps running, and you cant get the pickup that it had earlier. You feel that the clutch lever is pressed and hence the bike is not responding as much as the gas you are burning. It results in more gas consumption. You can keep adjusting the clutch lever, and ultimately, the limit would be reached when you cant tighten the lever any more. Time to replace the clutch plate/s.
And when the clutch plate/s is/are completely worn out, the bike will not move forward. it will just rev up static.

Can you slowly increase the revs? It sounds like an accelerator pump or debris in the carb.

Ford moneo turbo diesle s reg

there is a pipe witch runs from the diesel pump to the turbo which monitors pressure. sometimes a thin membrane in the pump goes releasing diesel straight in to the turbo especially on tick over. eventually that diesel is sucked in to the engine along with all the other gunk where it starts revving up on its own rattleing and banging. i have come across this on lucas diesel pumps before
