Hi, for the last two years my fjr leads left when i leave my hands from the handlebar. Does anyone else having the same problem? I have tried almost everything and heard everything from different technicians. This is how things are: I have bought the fjr new and after a static fall at 50000klm leads at left at any kind of street.

I have taken the fork system to calibrate but it still does it, I have also change oils at the fork system, I have change ball bearing, I have change disc brake

Now I have done 95000klm and the only reason that makes wanna sell it is this problem. Does anyone have any idea what it might be????

gaidaros,

I'm not sure what you mean by the front end was "calibrated", but my first suggestion is to make sure the 3 adjustments you can make to your front suspension (compression and rebound damping, fork preload) match each other on the right and left forks: To do this, Count the number of clicks as you turn each all the way CW to bottom - GENTLY -, then match the number of clicks CCW from fully seated on both the knurled knobs on top of the forks and on the flat-head screwdriver adjusters near the bottom of the forks. Make sure the number of lines showing on your preloads match (this adjusts with a smallish hex wrench - maybe 14mm? - at the top of the forks).

If everything matches, make sure your forks didn't twist when the bike was dropped. Loosen the pinch bolts and see if the fork tubes rotate in place.

If all of the above are okay, Is the fork tube dented? Did you lose any fork oil in the drop? Are your seals intact? Are the (damping) valves somehow compromised?

Good luck.

 
and, I am pretty sure that you're not supposed to take your hands off of the bars, either.

 
my suggestions are first... rider position, if your weight isn't exactly centered over the seat then you'll lean to the heavier side........... and second is road camber, all roads are cambered slightly to make water run off the surface and it could make you feel like you're leaning to the left...

 
Mine leans to the right...but I heard wearing tighty whiteys as a child was the cause. I wear boxers now but I guess the damage is already done.

As far your bike, if you keep your freaking hands on the bars you would not have a problem I bet. Perhaps you should wear boxers too?

See my post with the same question in early September. As for road camber: no, not all roads have a camber, or were built with a camber.

 
Mine does the same thing. If I let go of the bars the bike goes left. All surfaces, some more than others. It has always done this. Just takes a little body english to maintaine straight.

I tried everything I could think of. No change. I'm not worried about it.

 
solution: put more bricks in right saddlebag?

took mine off today and found the left one weighed more than the right - easier to throw junk in left one I guess. Maybe akin to Knifemaker's boxer revelation; one hangs a little lower than the other? i dunno

Maybe I should have said" most roads" have camber, and all of them in South and North Carolina do :dribble:

 
ME TOO.

2008 with 3500 miles and is has always needed a little pull from the left handlebar. I wasn't sure until I installed a throttle lock and let go. To keep upright, I need to grab the tank and lean pretty far over. It equates to a pound or so of pull on the handlebar and its just enough to be uncomfortable.

If you figure it out, please let me know.

 
I am wondering if this could perhaps be manufacturing variance in the rear end. Since the bike is shaft drive, a regular motorcycle alignment cannot be done. If there is any variance in the variance of the rear wheel thrust angle, correction will have to be made with the front fork.

 
Could it be effort required to overcome the centrifigul force (or whatever scientific force) created by the driveshaft?

Do other shft-drive bikes have this as well? (My other bike is belt-drive, so it don't count.)

I dunno. Just a thought that popped in my head. Never really noticed it on my FJR, though.

 
I remember the earlier post with the same question and it seemed like several owners could relate. Mine goes left too. If I do need to let go of the bars, I have to hang my right cheek off the seat a little to keep it straight. Not really a big deal to me so I've just learned to deal with it.

 
The problem could be you. Get the bike up to 20 mph then jump straight off the back. If it goes straight then it is you. If it still leans to left then you know it is the bike. Then again by now you might have figured out that the slightest amount of pressure to either side can cause the bike to move left or right. You would probably be surprised just how far your balance can be off. If you really want to see something interesting get a Wii and try the Wii Fit game. The Balance Board will show just how off your balance is. :headbonk:

In all seriousness I did notice the same thing on my bike. I attributed it to the way I hold myself while riding. If I straighten up and concentrate on the pressure I put on the foot pegs I can keep the bike going straight. I guess what my grandfather used to tell me is true, I am cockeyed.

Enjoy your bike!

I think you're pretty close. It could be a reaction to torque applied through the drive train wanting to tip the bike to the left. I'd think Yamaha would have compensated, but there might be a remnant left that does it.
