This is almost always a gummed up pilot jet. possible cures in ascending order of difficulty: 1. Seafoam in the gas tank 2. Yamaha carb cleaner, 50/50 with gasoline in the float bowl. Inject it with a pump oiler, follow the directions, chase with SeaFoam in the gas tank. 3. Strip the carb and unblock the jet manually, or replace it. #2 works almost every time.

Jud's right. This has never happened to my KLR, but my DR-Z has done it twice. I took the carb apart the first time; got smart the second time and used SeaFoam. It did the trick. BTW, why are you running premium? __Arden

Brian, Thanks for the thoughtful reply. I hope the overhaul will allow you a bunch of miles before you have to go to another tear down cycle. revmaaatin.

Randy, Just curious--what fuel stabilizer are you using? Your suggestion/results are completely contrary to my own experience. If it is Stabil, I would agree--but I quit using that 5 winters ago. I have several motorcycles that are not ridden for about 4-5 months in the harshest months of the South Dakota winters. The last tank- fulls of gas are ALWAYS treated with Seafoam (as I learned about it here at DSN) and nary a problem in the Spring, motorcycle resurrection. I also ride the bike until the carb runs dry, etc, when parking for the winter. That is what works in this environment...YMMV. etc. Contrary to your mechanic's suggestion (environment specific), cough, I wonder how long it is going to reach operating temps when the OAT is +10F or less for weeks at a time. For the conditions here, I don't think that suggestion is really a good idea as the operating temps will not get high enough to displace condensation in the oil without riding the bike for some time. My young riders cringe at anything less than +40F, so I don't think I am going to get them out very long in the winter to help do carburetor maintenance. shrug. On the other hand--the US military has ships full of tactical vehicles (prepositioned vessels) that follow that exact regimen suggested by your mechanic. They also have worker-bees that do it for a living.... following an environmentally specific regimen. On the other hand--there are winter over crews in Antarctica that deep-preserve certain vehicles and they sit until the spring thaw. Following the suggestions from our highly-experienced (and mildly opinionated) friends, plus following the directions on the Seafoam container has ended needless heartache and headaches previously experienced during the Spring reserection. revmaaatin.
