How To Diagnose And Fix A High Idle On Dirtbike!

A very high idle can be caused by an air leak or the throttle assembly. Air leaks are common along the air boot or the intake manifold. If you are more unlucky an air leak can appear in your left crank seal. Check the easy things first starting with your air filter, then moving along towards your throttle assembly to make sure your cable is not sticking. My problem ended up being a chipped carb slide.

Bro. U are a savior. No other YouTuber was even close to know what my problem was. Thank you so much. You deserve more clout. Good luck on your journey

Amazing troubleshooting skills bro. So cool and calm. Hope by now you found a fix for it. Thanks for sharing

My cr125 had the same problem with the cracked slide. Mine actually ran away a few times as well. I ended up putting a lectron carb on mine and it was a bit expensive but well worth the money.

God bless for the tips man, just bought a 99 wr360, scared the shit out of me thought it was going to blow up before I managed to kill it by tipping it over. Wide open on kick, figure it's the cable sticking so I'm taking the carb apart to inspect the needle and everything else. I'll put grease everywhere I can just incase there's an air leak.

Mine goes up and down up and down thoughts?

So I removed my carburetor to have someone rebuild it and when I put it back on I was struggling to put the airbox back in place, I don’t think I connected it probably to the carb. This is definitely the cause right?

Exactly how mine was going hopefully this fixes it

I have a problem with this tool, it's a KTM 250 2T
The tool has not been used for almost a year
This week I found time to take care of it, I did a fuel-oil change, I cleaned the filter plug, everything, finally I tried to start it, but the car could not start.
It only started with carburetor spray and shut off straight away
From that I understood that the carburetor needed to be cleaned and that's how I did it.
Now the problem is different, the motorcycle drives straight up to very, very high turns
I played with the air-fuel screw but unfortunately it didn't help.
Is there a situation where the problem is different? Something in the carburetor maybe? need help please

Dude when this first happened it scared the shit out of me I was so scared to even ride it lol. But it was the choke for some reason when I put the choke back in it was fine

[jamielesage]

Same exact thing happened to my cr125.couldn’t find a slide anywhere so we ended up having to buy a whole new carb

I'm having a problem with my suzuki Ax100 2 stroke, once i turn the fuel off, and the fuel in carb bowl is about to get get over, the bike shoots up in RPM, i know it gets a bit lean, my Yamaha does the same thing, but the bike dies in a few seconds, but my suzuki doesn't, it just shoots up and up...even Turning the ignition off won't kill the engine, it still keeps running ( rpm about 10k+) what could possibly be wrong? Another thing i noticed is that the carb becomes so chill, like an ice cube when the bike is running. Any help appreciated

It appear to be an excellent mechanic I couldn't hear what kind of valve you said that was that was a broken what kind of valve was that?

[tammydeluca]

Exact same thing my 1991 KX125-H2 does. Thanks so much for the help!!!

[xdmichal]
