From: Dokta on 11 Aug 2007 22:43 I have a 2006 VMax with about 1900 miles. Recently, I've noticed a problem where the engine stalls when idling. At best this is inconvenient when not in traffic and at worst, downright dangerous when in traffic. Has anyone seen or heard of this and if so, what's the fix? Thanks for any help.

It sounds like you think that engine stalling is somehow unique to V- Maxes and you expect a recall on that model to fix a design problem. All constant vacuum (diaphragm type) carburetors have very small idle jets, idle ports and idle passages. If you don't ride the bike at least once a week, the gasoline in the carburetors will start evaporating and the evaporated gasoline leaves gum and varnish behind to plug up the idle ports and passages and the engine will stall when it's warm. The alcohol additives in gasoline will keep the carbs clean if you ride regularly, but if you store the bike over the winter, you should use a gasoline stabilizer or when you take the bike out of storage in the spring, you should add 4 or 5 ounces of Berryman B12 Chemtool Choke and Carburetor Cleaner to a full tank of gas and go for a ride. Be ready to adjust the idle speed control knob. It's a knurled knob near the front carburetor on the left side. http://houseofmotorcycles.bikebandit.com/parts/Yamaha/VMX12V+V-MAX/2006/2128811 Also, the pilot adjusting screws are set at the factory, and the EPA requires that the idle mixture be set very lean. There is only one idle outlet port for each pilot screw, and if the carburetors get just a little bit gummed up, the idle outlet port will plug up. That's why I recommend running the B12 through the gas tank. You can get B12 in the liquid form or in an aerosol can for about $3.25. -- Message posted via MotorcycleKB.com http://www.motorcyclekb.com/Uwe/Forums.aspx/yamaha/200708/1
