Head bearing adjustment? - June 21, 2010, 02:09 PM

Hey guys,

I'm relatively nub at this stuff, so I am just wondering... why would I possibly need a head bearing adjustment at 2,300 miles? A shop recommended this after they completed an oil change.

Bike has been garaged and decently maintained, and this seems like a problem that arises further down the road. Any way I can tell for myself?

Not sure if it's related or not, but my bike has felt "bumpier" in turns. I think the suspension just needs to be adjusted though, or I need to get a steering stabilizer.

Thx,
corp

Well try this....If you get up to about 40 or 50 mph and over about 7 or 8k on the tach, let go of the bars (in a straight line of course). If you need a head bearing adjustment you'll see "head shake". If the bike tracks well and straight without any shaking of the bars or a feeling of uneasiness then you're fine. Mine needed a very slight tightening of the head bearing and it made a world of difference.

Definitely get your suspension looked at, can certainly make a difference regardless of feeling bumpier. Just be careful, sometimes they can set it too stiff for you're likings. My rear is set a bit too stiff and it wants to buck me off every once in a while.

Your steering head bearings shouldnt be lose at this point, but if they are they should be tightened, its a quick and easy job.

You guys would be surprised on how many head bearing adjustments are needed on new bikes! Plus other things that the factory misses.

There is a reason inspection of steering head bearings is one of the things listed in the Periodic Maintenance Chart of factory service manuals.

I tried the "let go of bars at 40+ trick," and there was no wobble. Either way, I may just get my oil changed and have them check the head bearings... how much do you think that'd cost to get done?

+1 I have tightened many steering hear bearing before the 5K mile mark. You can jack the front of the bike up and check for play as well as check the amount of force needed to turn the bars.
