valves in spec, cause that will do it too.

I had something similar on my GS450. It was a combination of not having the carbs synced properly and my float bowl height being off. At idle one of the carbs wasn't delivering fuel. If I dripped some gas onto the air filter on that side I could hear that it would start to fire.

So compression tested and got 150psi on the LH (Colder) side.. and 120/125 psi on the R (Hotter side). I did check the clearances when I rebuilt the engine and changed a couple of shims, but maybe rings worn on one side more than I thought..

thoughts guys
