2000SE rpm surge or slight bucking at higher rpms.

Postby peppilepew » Mon May 28, 2012 9:08 pm



I have a surge cruising at any speed that is irritating. This bike has only 15.5K on it so it did sit for periods of unknown length. It had a bad warm up surge until I cleaned the throttle plates. I did notice the right carb high speed mixture piston moving somewhat notchy. The left side was smooth as silk. Any suggestions? I tried Lucas fuel system cleaner which made 90% of the surge go away as long as I added the additive. 10 bucks a bottle and I would rather not carry it for fear of the bottle leaking.

Followup as to what solved the surge and bucking problem. I installed a tube on the carb cleaner and sprayed carb cleaner directly into the jets. I then used air pressure as the final step. i once again cleaned and lubed the needle valve. It ran like a top with all the surging and bucking gone. I must say that the lower end of temp does occasionally cause a low end surge. It is fine above 50 degrees.

I found out what the occasional idle surge problem was today. I had a coolant leak that required some investigation so i went all the way by taking the carbs out for vacuum hose inspection. They were soft and leaking. The coolant leak was the Y hose that goes onto the thermostat housing neck. The clamp needed tightening. These bikes are amazing pieces of engineering. I tip my hat to theses engineers.
