New owner with problem

Hello all. I just bought a 2008 in the mountains from an owner with OCD where his bike is concerned. 14000 miles and literally not a spec of dust or scratch on it. Picked it up this weekend in the mountains running smooth as silk. Trailered it to Holden Beach and it now has an intermittent miss during warm up and at operating temp it wonít take throttle off idle. You can work the rpms up but miss is still there. I thought it may have been the altitude change so I disconnected the battery over night with no change. Sorry if this is in the wrong place. Any ideas?

Well, the altitude problems with the CPU are supposed to have been taken care of by the 2008 models. How long did the thing sit?? Sure sounds fuel related to me but I am no expert. How far did you drive it before the problem cropped up? I will stop asking dumb questions now, hopefully the real mechanics will be along soon.

Seafoam in the fuel will take care of water if there is any. How old the spark plugs? Refresh the spark plug wires by unscrewing/pulling off the spark plug adapters, cut 1/4" off the wire, spread strands and thread the adapters back on. Check MAP sensor vacuum line for blockage and the sensor nipple itself. Could have a TPS issue.

Ike,

You can check the Throttle Position Sensor using the On Board Diagnostics, reading out on the data panel. Search for TPS testing in the Factory Shop Manual, or on the FJR forums.

Seafoam may be all you need, anyway.

ditto. Sure sounds like fuel problem. 14,000 miles in 11 years makes me wonder if it has sat for a extended period. Figure most of those miles were early in his ownership and then for what ever reason he stopped riding. Old gas sitting just isn't good. Sea foam very well could be the simple answer.

Thanks for all the tips. I bought it during last weekends monsoon and had to trailer it. It ran fine in the garage and onto the trailer. As soon as I started it up at home (sea level)you could hear the miss. I thought fuel myself but dismissed the old fuel idea because of the condition of the shop and the bike. Maybe I should rethink that. Iíll check the TPS and fuel. The map sensor was what my diesel mechanic son said. Iíll check that vacuum line. Thanks again for the tips. Finding the battery was a trick...guess Iím not in Kansas anymore Toto...I looked under the seat!

Ike I would change the brake and clutch fluid also. If stuff has been sitting in there for years it will be ugly too and donít want any ABS trouble. I own a 2008 with 46,000 miles and it runs great. Check serial number with Yamaha dealer and see if ground wire update and ignition switch have been done. If not get it done!

Throttle body synch might help.
