    I missed the memo. How do you go into CO mode on the dash. Is there a "how to" in the shop manual?

    Further, how do you set CO mode on a US model with no O2 sensor??

    Did you have one added on?

    ...here several months ago in this thread. Mine is a 2010 model. A buddy who showed me how to access the CO mode has a 2008 model and the procedure was the same. I have no idea if there's anything in the shop manual about this. I have one, but never looked. Just followed my buddy's instructions. He'd had his set up like this for about a year or longer when we did mine in February.

    We did have to jump a wire to ground from the lean angle sensor to allow us to access the onboard diagnostics mode.

    In the service manual Diagnostic Mode states:

    Turn main switch to off and engine stop switch to on. Disconnect fuel pump connector. Press and hold Select 1 and Reset, while holding them turn main switch to on and continue holding them for 8 seconds or more. Clock and trip should be only thing displayed. dlAG appears on the clock. Use Select 1 to select the CO or dlAG modes. After selecting press the Select and Reset buttons for 2 seconds or more to execute. The rest goes on to explain the diagnostic stuff and not CO settings but I think I read about those just using Select 1 and Select 2 to adjust the setting. I'm not sure how to save them or exit after selecting but it might be the same as the link provided above.

    I suspect this is another way to get to CO mode without jumping anything.

    Running my stock WR yesterday afternoon. Ran about 4 miles at 1/2 throttle then hit highway back home. Running full throttle in 6th gear for about 1 mile then shifted to 5th. Ran at full throttle for about oth 3/4 to 1 mile and hot light comes on. I let of throttle to about 1/2 or less and hot light went out in about 30 seconds. I was running slightly uphill and the ambient temperature was 106f.
    Do I have a problem?
    I am going to check water level and fan this afternoon.
    Radiator fins are clean.
    What else?

    Thanks guys, going to Western TAT at end of month and would rather not worry about bike getting hot. I have run it hard many times with never a problem. Why now?

    Question for those running a No-Toil Filter. I got one the other day for my WR250X, but noticed it's a bit different than other No-Toil Filters I've seen which have a hole in the filter and then part of the cage goes through that hole with a piece that holds the filter to the cage (see pic below). The one I got for my WR250X doesn't seem to have that though. There is a hole in the filter itself, but the cage doesn't have any provisions to "attach" to the filter. Is that the way yours is?

    A lot of people remove the plastic shroud from behind the radiator. I have removed mine and my bike sees plenty of high rpm, slow speed, single track use in the Oklahoma heat and I have never had my temp light come on. You might want to try removing that while you're checking fluid levels and fan fuses.

    I dont think the fan coming on at highway speeds would do anything for the cooling of the bike anyways, i was also going to suggest removing the shroud behind the radiator.

    I have a NoToil air filter and do not recall anything going through the filter( could be I am forgetting it). I use the stock cage in the inside and stock locking down mechanism on the outside. Shape of cage and hole in airbox holds everything snuggly in place.

    Thanks. So you didn't use the black plastic cage that came with the No Toil? Any particular reason?

    If it came with one..I probably used it. I honestly can't remember if mine did or not. I could have sworn I just used the stock one..since I had to clean off the petrochemical based oil that Yamaha used. I am due for a cleaning soon..so I'll know for sure then and report back.

    Thanks. I just thought it was odd No Toil put a hole in the filter if there was nothing to go through it and hold the filter on. If the filter moved around at all, dirt might be able to go through that hole, and that's why I was wondering if something was different about the cage I got with this filter.

    I'll be pulling bike out tomorrow night to get ready for weekend riding. I'll look into it then and see what I did.

    the super-flo kit that you got comes with its own cage that you are supposed to use , if you just bought the regular no-toil filter you use the stock cage.

    Ok, so aside from looking at the plug, how can we tell if the bike is running too rich or too lean?

    I have an FMF pipe, no EXUP and the FMF Fuel programmer.

    Through tip overs, and dumps, I've never had an issue starting, and the bike seems to run well on the highway and single track trails.....

    Heading to Bass Lake this afternoon to ride in the Stewards of the Sierra Fundraiser this weekend:

    http://www.dualsportmoto.com/boards/viewtopic.php?p=2488#p2488

    Bass Lake is STILL my favorite place to ride in CA......tough to beat riding at the edge of Yosemite......GIANT trees, lush forests/ferns, stream crossings, etc......

    Been there years ago - you're right just awesome. There was a real cool little General Store/Diner there - called "The Forks" I think? GREAT food and burgers!

    EDIT - Yep, here it is http://www.theforksresort.com/
