2007 Yamaha FJR1300 Fuel system Problems

“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. …”

“1) throttle fainls to respond properly when ascending to a higher altitude more than 1500ft higher than the starting point. 2) this has occurred on several occasions. The throttle will fail to respond when adding more throttle. The bike will begin to loss power until the throttle has been turned to add approximately 20% more, then it will accelerate abruptly. I have run off the road on a slow uphill corner while trying to keep up with the flow of traffic. I ended up being able to stop before I crashed into a snow bank. …”

“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.”

I was able to stop unharmed during that incident. The engine continues to run poorly after returning to the original altitude I started at. 3) throttle body adjustments have been made to add more fuel to the engine all the time. This has not helped. …”

“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. …”
