Yamaha WR250R Mega Thread

You can adjust the rich/lean mix with the built-in CO mode on the bike's computer. I removed AIS, EXUP, opened air box, and simultaneously installed an FMF slip-on pipe (no header) and changed to a K&N air filter

Once I accessed the CO mode in the bike's computer menu (you hold down this button, then that, then another on the instrument cluster - details are somewhere in this thread) it was set on minus 4 and I changed to a plus 2 or plus 3. That was 18K miles ago and bike runs strong and I've had no issues. It's never made any sense to me to pay for a programmer when my bike runs great without one!

So you just assumed that was a good mix? How do you know if your mix is good? Just listen to the bike and see how it pulls?

Do you recall the thread size for the eyelets? I don't have my WR with me at work and I'd like to get a couple of these ordered. Thanks

^^^^^ M8 X 1.25 IIRC. You can check fiche for the rear peg mounts to know for sure.

Thanks. McMaster has these in 304 SS for $5.17. Item 3100T11.

No, you can ride the bike and adjust on the fly. Then whenever you've got it like you want it saves the last setting when you turn off the ignition. I checked the spark plug to make sure it wasn't too rich or lean.

Not rocket science.

Bike runs strong and I haven't had any maintenance issues resulting in many thousands of miles. Works for me.

But if you'd feel better spending $200-300 for a programmer, by all means do so. Just relating my experience.

Yep, I ordered M8x1.25 thread, 13mm thread length. The eye bolt hole inner diameter, while not critical since it's just a nylon strap that passes through, is 20mm.

No problem. I had ordered these, to go with my wolfman rack/dirtbagz set up.

Is anyone using the Wolfman Expedition side bags without the side rack? If so how is it working out?

...this? Sorry, I'm pretty new at wrenching in general, and the WRR in specific.

Fuel evap canister that comes on California model WR-250Rs and WR-250Xs.
If you remove it, the world will expolde.

thank god i dont own a cal model more stuff i would have to take off :)

10, 9, 8, ... 3, 2, ONE!


sorry

I got a great deal so I'm willing to put in a little more effort :) Just tore apart the bike a little bit today to familiarize myself with all the stuff that's going away.

well welcome to the wr club youll love it

That's OK.
This world wasn't all it was chalked-up to be.

Adjusted my TPS. It was 15-96, now 19-99. When I test rode the bike, it was very jumpy just off idle and would stall very easily. Now I just need to finish installing all the add-ons (gas tank, rad guard, skid plate, etc.), service all the bearings, and wait 2 months for the snow to melt.

Thanks for the TPS Report.

Find yourself a nice cardboard box to store all of that stuff in. It's worth
money. Also the stock tank on your CA model is a one off from the rest
of the 49 state models with an extra fuel vapor fitting on it.

They're listed for over a $1000 bucks to replace compared to $300
for 49 state models, FYI.

I had noticed that. Mine's for sale!! $500! half price! What a deal.............
