I have a 1995 Suzuki DT90 that I have rebuilt the power head and carbs. now when it runs it goes to the fast idle then shuts off but will crank right back and run for a few seconds and then shuts off if I unplug the temp sensor it will run a little longer and then shuts off, if I unplug the throttle control sensor or the 12v to the CDI unit it will continue to run. I have replaced the sensors and down to what I think is a bad CDI unit. I have taken it to the shop and they have no clue. I need help, I do not want to invest in a CDI unit if it is not the problem.
