DT150 rough idle on start up

[lotzer91]

My '95 DT150 runs smoothly after about 10 minutes of run time. After starting the motor runs rough and will nearly die at times, oddly enough feathering the trim up and down during this time keeps the motor running. Plugs are fresh but was thinking it may be the CDI box. I have no way to check and was told there isn't a Suzuki tester available.
Any suggestions. Thank you.

Is it the fuel injected model or the carburated model?

run seafoam fuel system cleaner in it, it sounds like buildup in the carbs and seafoam will clean that out after a few tanks.

if its fuel injected then it could be dirty injectors which the seafoam will also clean out or just a faulty or dirty IAT (incoming air temp) sensor so it isnt getting the right fuel mix

Yes, it is fuel injected. Thanks for the suggestions.
