Altitude adjustment

The WR250R is a fuel injected bike but does NOT have an O2 sensor. Does it change mixture with changes in altitude and if so, how does that work.

Any 520 chain of the correct length [in links] will work.

Put on about 30K miles combined in 2 years of travel around this great country. It was my retirement dream trip, and I'm happy I did it. I have lost about 8 good friends to cancer in the past 3 years, so I wanted to get her done before it's my turn.

Below was day one of the trip - raining, of course. I just love my Hi-Vis PLATEX gloves. I turn 70 this year, and hope to still be riding when they put me in the home or in the ground.
Hey Blue Pill love your attitude and couldn't agree more with you. I'm a couple years younger than you. So I have been getting my rides in too. Stay safe and post up.

I appreciate the value of my bucket list more and more as it becomes shorter and shorter.

Like most EFI systems, it has a BARO sensor that tells the ECU what the atmospheric pressure is. A map in the ECU then adjusts the injection pulse width to compensate with a leaner mixture. The engine does loose power (as I found out in the Rockies), but the mixture stays near optimum.

No feedback loop is needed because air density is a very simple calculation.

I recently put Tusk 1-1/4" risers on, no problem with cable lengths. $20 / pair from Rocky Mtn Superstore.

I put the Tusk ATV sport bend bars on. Had to cut 1/2" off each end for the cables to not be too short.

Lunch in the Creek.



Ride Carnegie OHV park today and it was dusty, as expected. Hit the MX track At the end of the day and bruised some ribs. :)


Is it me or do these bikes have bouncy suspension?

There was a video posted a while back - it showed a guy getting bounced around quite a bit on his WR. The video was taken by the rider following the guy and comments were something like "what a bouncy suspension." It seems that either learning how to or getting someone to tweak the suspension properly is a popular and widely appreciated task.

On an unrelated note, I too had a great day on my WR250R (although my photos always suck - so why do I bother posting them? ha):
