Thanks for the info.......all this concern about "water getting in" cracks me up because my previous YZ/RM/EXC/CR dirt bikes ALL simply had a "dust cover" (side panel) and "lid-less" airbox (the "lid" was the seat).........not the closed/protected/"road bike" airbox that the WR250R has in stock form.......if you submarine the bike you're in deep "water" regardless......

Does anyone have the spring rates for the R & the X? And are they different?

According to the service manual they are the same.

Front spring rate: Spring rate K1 4.60 N/mm (26.27 lb/in) (0.47 kgf/mm)

Rear spring rate: Spring rate K1 80.00 N/mm (456.80 lb/in) (8.16 kgf/mm)

There has been more that one occasion where I was able to ride back home or to the truck after going swimming with my WRR. Had I removed the lid to my airbox, I would have been walking. I have also towed a WRR out of a creek and back to the truck, using my WRR as the tow vehicle, not fun. After these experiences, I think the current HF airbox mod is the way to go

Thanks much. I am a bit puzzled as my problem is the front end diving & rear kicking up on whoops. I know the rear is due some what to poor rebound damp. Race Tech reccomends softer 449KG in forks & stiffer 8.70 in the rear??

Talk to Javier at Trail Tricks, he just did my suspension and got rid of all that. The bike is completely transformed. Front and rear are balanced now and the stink bug is gone. I can ride the bike much harder and faster then before. The action is very controlled now. Very satisfied. A+++

Sunday fun.

After the previously mentioned "swimming" exercises with my WRR, figured it was time...
Time for new tires, time for new bits, time to upgrade my suspension, time to get the mud out, and time to get some grease in.

Take your shoes off baby, make yourself comfortable.


After cleaning this wound several times, she's still bleeding.



Guess it was time to remove the skid plate and address a few obvious issues here as well.


Loosen 4 bolts on the triple clamps, twist, pull, cuss and then twist and pull some more. Eventually her legs will come off.


Old wire hangers are always handy to have around.


Using HF's method of grabbing a few wrenches and "getting after it", sure enough, her pants come right off.








The bolts holding the swing arm, relay arm, dog bone and shock in place were all showing signs of wear. Similar to what HF found, mine had extreme wear marks that you can see and feel, and even some pitting from corrosion.


Once I got the swingarm off, I flipped it over to see if I had any chain damage. I probably wouldn't have thought to check for this had it not been for 10Cup finding it first.


Judging by the amount of mud, water and grime that spilled out while taking all this apart, I think it was definitely time to freshen things up. I stuck my finger in a few of the bearings and they feel like they are packed with sand and mucus, not grease. I'll post up the horrific pictures of my bearing's contents and reassembly process as soon as my suspenders are completed.

Good idea and thanks for the pics.....we don't don't do much swimming out here in the desert but the sand can be equally vicious.....

Good/cheap alternative solution to mounting the license plate too.......how is it affixed?

What size front sprocket do you have? I have a theory that a 12 tooth sprocket will cause more damage than the 13 tooth will. The other question is that what can you do about it?

I agree, smaller front sprockets can accelerate chain wear and front sprocket wear as well.

Put a bigger rear sprocket on than front sprocket. Might need a little more chain too, if you do that.

Who cares? ......I'm throwing on a 12T just to blow out the stock/rear sprocket and chain.......once that's done, I'll put the stock 13T back up front along with a quality X-Ring chain and a 46T rear sprocket

Watch the wear on the plastic

Not sure, but I use a 13T front and try to diligently watch the chain tension, I would expect a too tight chain could cause some extra wear but also the more you lower the rear with preload or the Yamaha shock adjuster the closer the chain will run to the plastic guide.

I believe it will be a wear point we need to watch and will require replacement depending on riding styles, sprocket size, swing arm position due to ride height etc. I consider it a wear item like the chain. It's a $40 item with shipping so hope fully its not more than that.

One thing to watch for is for the chain to get shinny on the outside of the link plates which means it has cut a groove into the plastic and is being polished by the guide.

I was not talking about chain wear. I am aware of the difference of tension applied to the chain at the smaller radius of the smaller sprockets and also the extra bending required from the chain. The picture showed wear on the swingarm and that is what I am concerned with. Would a 14 tooth countersprocket move the chain further away from the swingarm and reduce the rubbing. So boogn1sh, could you tell me what size sprocket you have on the front?

By the way, I have already changed the gearing to 13/47.
