Hi, hoping someone can help with the issue I’m currently having. I have a 1981 Suzuki GS650E. Engine was running fine with good compression prior to taking the engine apart to fix a transmission problem.
Now that the engine is back together I can’t seem to fix the issue I’m having with cylinder 4. All other exhaust pipes will run hot except 4 which runs cold.
I completed the following with no success:
- check coil plug on 4 and it sparks. Tried swapping coils around and cutting the coil wire and it’s still cold.
- throughly cleaned the carbs and check float multiple times. No fix
- checked compression on 4 and it’s ~125psi
The spark plug on 4 is wet. Seems to be oil as it’s going through number 4 exhaust making it smoke white. Exhaust is now backfiring on idle and usually have to use choke every time I start the bike
any help will be much appreciated
