Yamaha WR250R Mega Thread

Love the trackmaster.
Dunlop 756 on the front.
I air up to 20-25 unless I'm in nasty mud though. It helps the spongy feeling of a MX tire.

I have TM2's, on my DRZ. I used to ride 50 ish miles round trip to get to where we would ride. I felt they wore down quicker than I would have liked, but did do well enough in the sand...the front not as well. That is when I went to the Pirelli XCMH's I am on now.

The spongy feel is what we have to have for the sand.

We got Travis to re-do the suspensions of our two WR's. For those of you who are wondering if it is worth it…It is. Go-Race suspension for the WR makes a HUGE difference on and off road.

I made the decision after struggling on very steep and rocky terrain and blowing front fork seals on three different week long trips. September of last year I also tested my riding's partner KTM. I then started reading on the web about what to do. Go-Race is not going to convert the WR into a KTM enduro or MX racer, but it does allow the bike to handle with much less strain and less effort on any condition, but especially when it gets rough, taking for riding to the next level. Needless to say, the KYB seals are great too and so far, no leaks.

Here they are doing Lockhart Basin and Elephant Hill in Utah a couple of weeks ago:

Nice. Always like to see action shots!

Anyone having "exposure" problems i.e. puntures, breaks, ruptures in their aftermarket tanks?
I really like the IMS 4.7 gal. but, I've only seen one mounted. It sure looks like that tank would be compromised on a fall-over, not to mention a GOOD fall-over.:eek1 I'll part with the $400-500 but kinda scared of bustin it. Sure do like the idea of 200-300 mile ranges though!

The plastic tanks are much more durable than the steel ones.

When I had a KLR 650, the going suggestion was to get an IMS 6.6 gallon tank, because it was so tough that the tank shrouds would protect the radiator in a crash. Thus, by buying the tank, you did not need to buy radiator guards.

I've biffed more times than I can count on the old KLR w/ IMS and on my previous WR w / IMS. Scratches aplenty, but never any leakage.

I had an acerbis 6.3 gallon tank on my last bike and I bought it well used. There were several deep gouges in it and I fell a few times doing up to 40 mph on some hard packed large gravel and it just adds more scratches. I never put anything larger than the previous owner had. I would think it would take a good fall on a really pointy object at the perfect angle to bust one open. Or maybe a car wreck.

Anyone know the thread pitch and size for the oil drain bolt? Lost mine going down the road this afternoon, out of spares, hopin the local shops have one in stock but given their previous record I'm not holding out hope. Motor is fine i think given the nice pool of oil tgat spewed out when i stopped.

12mm/1.5 20mm long

Funny that you posted today, I was about to ask a similar question. I dumped and added some character marks to mine yesterday. Glad to hear that they are so durable. A good portion of the cost is probably the diaphram pumps that suck fuel out of the wings. A replacement tank only might be less expensive from IMS than the full blown kit.

I noticed in Autozone the other day that they had a pretty good selection of drain plugs. You might check there if other sources fail.

311 miles yesterday, all but 96 on dirt.

Oops...

One with the bike.

Got a new drain plug and washer this morning, also finally changed the gaskets on the oil filter cover. So far so good, still runs smooth and no new noises... think i dodged a bullet with this one...

I always put a little bit of loctite thread sealant on every time I take any drain plugs out. Basically just a paste form of Teflon tape and I have never had a problem with leaks or fallouts.

I use yamabond. Though I think I have the honda equivalent right now.

+1 on the Yamabond #4. Good stuff, Maynard.

p.s. Duc plugs don't fall out..........

Does anyone actually do this?



High Five, an experienced wrench and WRR expert, doesn't mention it in his how to:

No other bike I ever owned had this step. If I need to, I will, but it seems strange that only the WRR/X needs this done.

TW200 has a similar oil flow check bolt.
