Suzuki DT30c Starting problems.

[Ryan.L]

Hi Guys,

I have a 1989 model Suzuki DT30c which has me baffled. It won't start under normal circumstances. It will only start when I remove th plug leads on the top and bottom cylinder, it fires up and runs rough as one would expect when running on one cylinder. If I then turn it off and put back the plug leads on the other 2 cylinders it then starts on all 3 quite nicely. Has anyone got any thoughts which may help me to get it going properly. Thank you!

Very interesting?
How long has this been doing this?
How does the motor run once started, will it restart over and over after the first start?
What have you done to try to correct this problem?
Have you checked for spark at all cylinders, compression?

Post back when able.
