Hi I've gota DTR 125 54 model Bike was rev high won't idle unless choke was on. When i turn choke off it revs high then cut out. So I clean pilot jet main jet did looked a bit blocked. but all clean now, I then checked for splits in rubbers all tight and now cleaned. Now she runs without choke but only when revving high if I let her go to idle it cuts out. any thought splease cheers

I got the same problem with my dt 125, it got high rev even if i pull the spark plug cap free from the spark plug it keeps on reeving, it will just stop if i pull the choke on, any smart ideas please? im all out of it,

It would be best if the whole carburetor were soaked in carb cleaner and then blown out with compressed air. You could have a plugged up passageway in the carburetor. If you take this route and use comercially available carburetor cleaner, DO NOT put any rubber or plastic parts from your carb in the carb cleaner as it will ruin them. As for the jets, make sure you can see light through them. I usually take a strand of copper wire (like from stranded automotive electrical wire) and run it through the jets to make sure they are clean.
If this fails to correct the situation, check the engine's compression. Low compression will cause the engine to not run at low RPM. You need to see at least 140PSI of compression (throttle wide open) in order for the engine to idle. If the compression is low, adjust the valve tappet clearances. If this fails to bring the compression to a normal level, then the engine needs internal repairs.
