"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.

This is related to the new yamaha 2007 fjr1300a. The ecu doesn't appear to take realtime barometric readings. This is very apparent when you change altitude on mountain roads, which causes a very unsafe condition where the motorcycle hesitates when throttle input is applied. The hesitation gets longer the higher you go. It is a consistent, repeatable issue, and happens every time I ride in the mountains. I have reported it to yamaha, but they deny the issue exists.

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 100% stock 2007 yamaha fjr 1300 that just crossed the 1,000 mile mark. I live at ~5,000 feet above sea level. In the first few hundred miles or so it seemed to have a slight hesitation in the lower RPM's (1,500 - 2,700), that slight hesitation is getting worse and is now pretty "jerky". A few times it just seem to stall when starting off. It is starting to make me nervous to pull out into traffic.

While driving through a mountain pass (3,00ft), throttle control became unstable with engine hesitating then surging. After exiting freeway the bike violently slowed/speeded up when trying to get up to speed. The fact no other traffic was present prevented an accident. After shutting the bike off and restarting it operated normally until I drove back down to sealevel where the problem briefly repeated. I have since learned that this same problem is happening to other owners and there have been no warnings from the dealer or manufacturer. I will take the bike in for service when they open this week but reports from other owners indicate the manufacturer has yet to verify/correct the problem.
