    Hi,

    Does anyone know of any differences between the 2008 model year WR250R and the 2012 or 2013? I've found an 08 with very low mileage for a good price I'm thinking about buying.

    Thanks

    There a few internal parts that are different, like a different crank pin and one of the crank bearings. Long story short not much, if you found a good 08 buy it in a heartbeat!

    Yeah...downfall of southern NJ. All the sand I want....but no mountains, hills, or any real actual dirt. I was envious watching Dakar, thinking how cool hills would actually to be to ride.

    Hi,
    There are no major differences for '08-'12. Some '08 had fuel pump problems, mine has not had any issues. Changes where all cosmetic, some say the new ones with the gold forks are faster, I don't know, I'm not good enough a rider to need a faster gold forked WRR.

    If it's any consolation, there are no hills in the UP either.

    I asked this earlier but I guess no one saw my post:D, but can I run the stock chain if I move up to 13/46 gearing? Thanks!

    No pretty sure 45 is the max depending on tire with stock chain.

    No, you'll need a 110L chain for a 13/46 combo. 45 barely fits, but is much happier with a 110L (its what I'm running currently).

    For some reason, I was thinking stock chain was 110 links, but now I remember it's in fact 108. I can't imagine 108 will work with 13/46. Sorry.

    44 is as big as you can go. I've been running one since July, and you notice the "slight" difference you might think. I'm getting ready to put on a new chain and go to 13-47, so If you want a 44 with 800 miles on it, I'll sell it for $25 shipped. It uses your stock bolts. Steel sprocket.

    Thanks, but I'm probably just going to do the same as you and get a new chain and sprocket. Thanks for all the replies.

    While looking for an Ignition Hot to tap into I shorted and lost power to my ignition, headlight, tail light, brake lights, horn, and dash console. The blinkers still work and the fuel pump powers up fine. I checked all the fuses and they're all good which makes me think I did something to the Relay Assembly.

    Anyone know of a way to check the Relay before I spend the $

    If memory serves me correct. There is two locations for fuses? One on the left should side or something? But I could be wrong. Been that before.

    I've checked both spots, the 30 amp main is good and all of the individual fuses in the Block are fine as well

    Go ahead and put a 47t steel sprocket on her with a 112 link X-ring chain. It's a good dirt ratio without sacrificing the highway too much...IMO

    Remember your speedometer will be way off after any final drive ratio change.

    What's the most "mileage" anyone gotten out of a fuel pump?

    Well, it's time for me to sign out all! I hope you all got a little bit of info from my build. It will be in my signature for a while, so check it out. The WR250R went to a new home today, hopefully it gets may more good miles on her as it gave me.

    Farewell.

    I'm pretty sure the relay for the lights is the same as the other small relay.
    Try swapping the two relays.??

    You can also check the continuity of the relay.
