2007 Yamaha FJR1300 fuel system problems

The fuel tank cap assembly allows water to leak by the rubber gasket into the vent pipe. This pipe is made in such a way so as to trap water in it when washing or riding in rain. This is then evidenced by a gurgling sound coming from the fuel tank cap area. If the problem is not corrected it could, over time, cause the vent pipe to rust through. This would then allow water to enter the fuel tank and contaminate the fuel, which could cause the engine to stop suddenly. If this were to happen while the motorcycle is being ridden it could result in a crash causing injury or death. A temporary fix is to remove the fuel tank cap assembly and use high pressure air to blow the water out of the vent pipe. This must be done each time the area is exposed to water. There is not a replacement gasket available from yamaha. Currently, the only option for owners is to purchase a new fuel tank cap assembly, for over $100, and hope this fixes the problem.

Engine surges above 3000 feet altitude causing uncontrolled lifting of front wheel in first and second gear.

"altitude sickness" with 2007 yamaha fjr. Motorcycle does not accelerate, sputters, and hesitates, until 3500 or so rpms reached. Happens when altitude is changed, or out side temperature changes, especially when above 85 f.

When the engine is decelerating or braking fuel is turned off and when trying to accelerate again there is a delay in fuel delivery. When trying to enter a highway from the ramp you decelerate to time your entrance and when you accelerate the motorcycle pauses then lurches forward effecting your merge into speeding traffic. This also happens to a smaller degree on each shift of the transmission. It appears that an air pressure sensor in the intake manifold prevents the flow of fuel during increased vacuum and that the fuel is not turned on again until the vacuum is reduced by an open throttle. You open the throttle, the vacuum goes down the fuel turns on and the motorcycle lurches forward.

While on a 5 state tour on our my motorcycle this summer. My fuel system seemed to dangerously surge. The bike would just slow down and then to recover I could give more throttle. With no response, then more throttle and the bike would just take off. This only happened when I was changing altitude. Changing up hill and changing down hill. On mountain roads in colorado in a 15 mile per hour corner and your bike just quits making power then suddenly recovers with almost full throttle. We are lucky my kids still have parents.

While riding the motorcycle in question in the mountains the elevation above sea level changed from 1500 to 5000 feet and descended again. While ascending the mountain at low speeds (25-30 MPH), the engine did not respond to throttle input and began to stall. Right before stall, the engine would suddenly accelerate violently. Changes in altitude of approximately 800-1000 feet seem to correspond with the problem. Shutting the engine off and restarting it appear to resolve the issue temporarily, that is, until the altitude changes again. As a result of the bike's erratic behavior, I nearly dropped it time while trying to re-enter the road from a parking lot. Two other times it was difficult to control while negotiating low speed turns in on the mountainside. To date, yamaha mechanics have said my carburetor needs to be adjusted. However, it is difficult for them to repeat the problem because we are at sea level with no significant elevation changes within reasonable distances for the mechanic.

My 2007 yamaha fjr 1300 motorcycle purchased in may 2007 has a verified inability to deal with altitude changes of 2000 ft. Or so in either going up, or down in elevation. During the periods the motorcycle hesitates and then surges during these periods. This is alleviated by pulling off the road and then restarting the engine, but the act of hesitating/surging while going around corners at speed limit can be dangerous both the rider, vehicles behind the rider, and potentially to oncoming traffic. This issue has been recognized by my dealer, desert valley powersports of prosser, wa. And reported to yamaha corporation. I have requested several times to have this issue fixed and am told that they know of the issue, there is nothing they can do about it, and yamaha is working on a fix. Separately by another dealer I am told that this won't be fixed by yamaha and is an issue with the 2007 model.

I have a yamaha motorcycle that I purchased in march of this year that exhibits a serious problem with the fuel injection system. I have contacted the dealer where I purchased the motorcycle and they took no action. I have contacted yamaha directly. The product specialist I spoke with in cypress, ca advised that they were aware of the problem, but would not offer any details about how yamaha plans to correct the issue. The product specialist further advised that a service bulletin would be issued to dealers and letters would be mailed to customers within two weeks to one month, however, I have discovered that other owners were told the same thing many weeks ago. This is a serious problem that causes the motorcycle to be severely under powered whenever it is operated at high altitudes. The first time that it occurred I thought that I was running low on fuel, however, this was not the case and the motorcycle will exhibit these symptoms any time that high altitude roads are encountered. This is especially troubling and frightening when it occurs while negotiating corners or stop-and-go traffic situations. I am including a link to further information: http://www.fjrforum.com/forum//index.php?showtopic=23179 thanks in advance for looking into this matter. The date that I am entering below is the most recent incidence.

Fuel injection surging during and after altitude change, leading to unreliable throttle response which makes controlling the motorcycle difficult. It requires the ignition be turned off to reset the fuel injection.
