Hi, David and the usual suspects are:
1. Throttle cables improperly adjusted, pinched or need lubrication.
2. Idle adjusting screw needs to be backed off.
4. Air fuel mixture adjusted too lean start with 2 full turns.
5. Intake system air leak.
6. Fast idle choke ramp is not releasing.
7. Broken throttle return spring.
8. Damaged diaphragm or slide.
9. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector

Are you running on original pipes or have you installed aftermarket pipes that are louder ?? I had the same problem with aftermarket pipes and come to find out my carbs were not jetted the way they were supposed to have been done when I installed the pipes.Also there are two chrome tubes starting at the front of the engine going under the seat towards the rear--- there is a rubber hose connection connecting each side .You should disconnect these hoses and bypass the tubes-- in other words use one hose to connect the front two tubes together and the other to connect the rear tubes together , its some sort of early emmission thing that will cause some backfire

check the inlet manifold rubber has not seperated from the aluminium part of the manifold ,this is very common on the ttr 250 and will cause the exact problem you have,if it is seperated either replace it or repair it with some good quality rtv sealant avoid sillicone sealant as it is not petrol resistant and will turn to jelly.adam

The CDI unit on the 83 model (TT600) is located under the fuel tank and suffers from heat
exposure.The solution is to get specialist help to open up the sealed CDI unit and repair/
replace internal connections (which are readily available electronic components)
When you re-install it put some heat shielding material there to protect it and this
will be OK as repair will utilise stronger parts,I think.
Later models have the CDI unit moved to the head-stem area.
