I had a problem with the bottom headstem bearing on the WR250, it was full of mud and dirt. The race looks good and so do the bearings, I think I am lucky that I check them about every second oil change, so every 1000kms. The bearing seal looks fine, but this was obviously the problem.

I have a sneaky suspicion that it happened about two rides ago as the rain has started to come, and the puddles have to be ridden through. :applause:

I really noticed the problem when I put the new suspension on, it didn't want to turn at all when riding. I first thought it was just the new suspension just bedding in, but when I put the bike on the stand, turning the bars took some effort.

I also suggest you check your bearing right away if you have a new bike and haven't greased them yet, Yamaha doesn't like grease for some reason.

Bearings are cheap. I just replace them all once a year. Grease and clean them only between mud rides. :applause:

Why keep stripping them ????

For a few cents you can fit a grease nipple into the head stock and grease them after EVERY ride like I do :applause:

It wont help if mud gets in! Just one grain of dirt can destroy your bearing or race. Great idea though! Too much grease can be bad too!

There is NO way mud will get in if you keep them pumped full ....both this 426 and my last 426 had this mod (which took a few minutes to do) and that covers 5 years of ownership with no problems ....as the oil in frame warms up , it melts the grease and keeps the bearings nice and lubed ...grease slowly comes out (so NO mud gets in !!)
Shorely I dont need to post a picture of a grease nipple in a head stock ??? you get the idea !! I use a "cranked" nipple and put it on the right side of the frame where it can easily be got to with the forks turned left .......so ...drill 6mm hole....tap thread ....screw in nipple ..... pump full of grease....job , jobbied !!

A good idea on any Manufacturer newly purchased bike. Dirt or Street.

The way I see it, you drill the hole through the race and install the nipple right at the bearing? One for the top bearing and one for the bottom bearing?
If you put one nipple in the center of the steering neck you will just pump the cavity full of grease and the bearings would never see any of the grease.
There was some talk of this a few years ago, one guy did his swingarm and shock linkage too!

I wouldn't go drilling through bearing races. Bearing inspection is much more important than just greasing them.

It is not hard to remove headstem and grease them properly. Do this every 6 months or so, the grease lasts a long time.

I just remove front wheel, remove headlight (just 3 bolts and disconnect!), remove forks, remove bars, remove top triple clamp, get a screwdriver and tap nut to undo stem and bottom clamp. The top bearing comes straight out, the bottom bearing stays on the stem. The races stay in the frame. Clean all grease residue off bearings and frame then dry. Inspect them for smoothness / pitting / obvious damage. Pack the buggers real well with your favorite waterproof grease and then put everything back together. All up, 1/2 an hour to an hour job. :applause:
