Whining

[Shadowfax]

I took my FJR to a local dealer when it started running rough at idle.

After 4 weeks they returned it saying they sync'ed the throttlebodies and adjusted the TPS.

Now I have a loud whine (like a bad bearing or a turbo) until the bike is warmed up.

If I start the bike in the garage you can now hear it plainly in the house until it warms up - then you can barely hear anything.

WTF did they do to my bike? (and no I don't think they installed a turbo, thanks for asking)

I don't have an FJR service manual -- so, I'm just taking a stab-in-the-dark (maybe someone who has a manual, and is interested, will look for you?).

Some things that whine are: too tight an adjustment on balancer shaft drive gears (if adjustable?) and too tight (too much pressure pre-load) on the cam chain tensioner. The cam-chain tensioner's "automatic" -- so they would have had to take it apart and "booger" it, somehow? Too tight a gear fit, anywhere -- but, hardly something a dealer would do for "rough idle". Altho -- they did have it 4 weeks....?!

can you pinpoint the area the noise is comming from? Does it sound like it could be air escaping through a loose connection. Say an exhaust-muffler gasket or reeds in the air injection?

If you have a piece of tubing you could stick one end in you r ear and plug your other ear and start the bike cold and use the tube to try and find the noise. If it's coming from inside the cases I"d say take it back. You may want to do that anyway.

It's not air, it's definitely a mechanical sound.

I assume they were trying to figure out why the bike ran rough at idle and started screwing around with moving components before they established a baseline (ie TBS and then TPS).

They only thing that irritates me is they knew it sounded like this when they told me it was done - and all work was done by the service manager.

I'd say a pretty good indication of the quality of work done there.

I assume you are talking something in excess of the"normal" turbine-sounding whine the FJR makes. Mine, and every other FJR I've seen/heard have a mechanical whine. Maybe some straight cut gears somewhere??? How is the sound compared to other FJRs?

 

[Shadowfax]

Bike was dead quiet before the "repair" but I have not put it next to another FJR.

 

[madmike2]

I'd try to find another owner close to your area and listen to both bikes./ The FJR "normally" has a whine (but no cheese to go with it ).

Which dealer?

There was no whine before the repair, there is (almost) no whine after it is warmed up.
