Sorry, I fit the earplugs then put my helmet on. Took me a while to figure that out!
Had that happen once on my last run too. After 10-15kms riding. But I could feel the engine was not 100% at ease - was lumpy at tickover too. Later on the lumpyness faded and the engine felt as it usually does. I had assumed this was the COOBER, but maybe not. lain:And sometimes even when the enigine is hot after bliping the throttle a bit the revs will drop below 1500 and it will stall.
