![]() ![]() ![]() ![]() Since its inception in 1985, the Yamaha VMAX has maintained a reputation as a brawny, performance-packed moto-monster.Ĭonsider the 2019 VMAX model: it comes with a powerful 1679cc engine that delivers around 123 pound-feet of torque. If you’re the owner of a 2009 Yamaha VMAX and you’re unsure if your wiring harness has been upgraded, pop into your local Yamaha dealership to run your VIN and find out. Yamaha called for their mechanics to replace the wiring harness at no cost to owners. Recalled motorcycles were fit withĪn additional sub-lead wire to bypasses the problem area of the wire harness and prevent excessive resistance. To rectify the deficiency, Yamaha launched a Factory Modification Campaign. This prevents a proper return to idle and, in extreme riding situations, could result in a crash with injury or death It can also retain idle speed from dropping below 3000 rpm when the throttle is released. Yamaha announced that on affected motorcycles, there could be extreme electrical resistance in the ground wire for the Accelerator Position Sensor (APS) and the Throttle Position Sensor (TPS) due to an inadequate connection.Įxtreme resistance can transmit false signals to the Engine Control Unit (ECU), potentially leading to unsteady engine idling. Faulty Wiring LoomĪnother speed-bump in the VMAX journey was Yamaha’s recall on 2009 VMAX models due to faulty wiring. If you happen to buy a used VMAX produced during that timeframe, take it to your local Yamaha dealer to run the VIN and make sure your bike’s been fitted with the upgraded oil pump. The recall required dealers to replace the faulty oil pumps with new units, free of charge. Like we mentioned earlier, Yamaha issued a recall for the bikes affected by the problem on over 23,000 models produced in 2008-2011. In severe cases, this causes damage, resulting installing and the bike’s failure to restart again. When the wear and tear passes a particular point, the pin disconnects from the inner rotor and oil stops flowing through the engine. This causes wear and tear at an alarming rate. This pressure can push the oil pump shaft’s thrust washer into the oil pump housing. In 2011, Yamaha issued a recall on particular VMAX bikes released between 20 due to malfunctioning oil pumps.ĭue to the fault oil pump on affected motorcycles, high oil pressure can develop inside the oil pump. The oil pump is the component that circulates that lubricating oil throughout the bike’s motor.Ī faulty oil pump can lead to anything from overheating to engine damage. Oil is what lubricates a motor, assisting with friction between the metal components and with keeping the engine cool. Here’s another one we’ve encountered with owners of older VMAXs. Idle the bike for up to five minutes with the choke pulled before riding, but be sure to push the choke back in before you hop on and take off once the five minutes have expired. Pull your choke out, and you’ll find it starts easier. This is normal on carb bikes, especially in the cold. ![]() This starting problem is even more pronounced during cold weather. System cleaners are available through auto part retailers and most large retail stores.Īdding fuel system cleaner liquid to your fuel tank will clear residue that may be blocking your fuel lines.Īnother common problem riders have on older carburetted VMAXs is trouble starting their bikes, cranking multiple times before running properly. Since most faulty fuel lines result from dirt that clogs the system, a system cleaner can solve it. Your engine will stutter and may stall.The term “lean” refers to the air: fuel ratio a lean mix has less fuel and more air than it needs for the ideal combustion needed to run the bike as intended. The fuel pump transports gasoline from the tank to the engine.įaulty fuel lines will reduce fuel supply to the engine, not only causing the bike to run lean but it explains why the old-school sensors think the tank is empty when it’s full. One of the more frequent culprits of the problem is a clogged fuel line/pump. Some reports state that the ‘low fuel’ light warning light stays on even when the fuel tank’s full. Like any old bike, an older VMAX can stutter on occasions or even stall out completely.Īccording to a few of them, the bike acts as if there’s no fuel left in the engine. The Yamaha VMAX has been around since 1985, so naturally, there are riders out there ripping around on models 30+ years old. What’s The Resale Value On the Yamaha VMAX?. ![]()
