2007 Yamaha FJR1300: jerking or lurching

Filed Apr 8, 2009 · Transmission · 1,151 miles · CA

I purchased a brand new 2007 fjr1300 yamaha in june of 08. To date motorcycle has 1151 miles on it. From day one motorcycle had a very sticky clutch. I always warm up the bike to 2 or 4 bars and then attempt to put bike into first gear, pull in the clutch with brake applied and bike would shut off. I would restart the bike, pull in the clutch with brake gently applied and bike would clunk into 1st and lurch forward. When coming to first stop, trying to downshift from 3rd to 2nd or 2nd to 1st there was a 1-3 second delay regardless of RPM, and at times would not downshift at all which meant I would come to a stop with clutch pulled in. As the bike would warm up the clutch became less sticky as I rode around town. However, once I rode on freeway to work, approximately 35-50min ride, and tried to downshift on the offramp bike again was sticky or would not downshift without 1-3 second delay. This became progressively worse until I felt my life was in danger and I took bike into dealer at 1151 miles. Dealer opened up clutch and found that 2 clutch tabs were improperly pulled in? Dealer also stated that washers were not assembled properly. I have yet to ride bike since repair.

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.

When initially shifting into first gear a loud clunk is heard in the transmission and the bike will lurch forward and take off or if the brake is apply the engine will stall. Then the clutch breaks loose and you can drive away. The bike will upshift hard and shift timing is critical. Then when you approach an intersection and need to down shift you need to use the brakes to break loose the clutch. After several miles it warms up and becomes less sticky. The clutch will disengage after a few seconds and then you can shift. If you don't use the clutch for several miles it gets sticky again. If you let it sit for 8 hours it gets locked up. This started mildly at 500 miles and has got progressively worse. This can be very dangerous for an inexperienced rider.

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.

Problem occurs during, or shortly after changing altitude. Usually begins with a slight surging at steady throttle. This progresses to a non-responsive throttle. Open it slightly and nothing happens. Open it further and it comes on with a jolt. Sometimes bike lurches like its running out of gas. Very dangerous especially at low speeds or in traffic. On 7/2/3007 yamaha customer relations said I was the 1st caller with these symptoms.
