several of us have had this happen to the KLR...if it finally gets caught up there then it is easier to diagnose and correct as the machine will flood and flow fuel out the breather tube... Kurt

Mine used to go away too. I always blamed it on bad gas. I'll never forget crossing the Sierra Madre Oriental in the Mexican state of Tamaulipas. I was climbing up a curvy pass surrounded by Mexican (of course) semi-trucks. The engine commenced to hic-up and didn't stop till I hit the summit some 5 miles away. There was no place to pull over. Least I survived, I think. (I might be an invention of some list prankster) The rest of the way to Colorado the engine didn't miss a lick. Yeah it may come down to a full inspection; will have to wait till Christmas break. Thanks Kurt, Bogdan

Interesting Satyr, From that description my memory says fuel but I'll listen again. Thanks, Bogdan

Would seem to me that since it ran well in the reserve position, the problem is fuel related not electrical. Possible that the modification stirred loose flotsam up in the tank and the filter is plugged early. Also possible that the higher intake position of the non-reserve position is somehow compromised. I'd run without a fuel filter first and see if the problem persists. Then run the tank out and inspect the petcock intake for partial obstruction. Todd A9
