    I am getting a Dunlop 606 front tire (90/90x21) and rear tire (120/90x18) to replace my aging stock WRR tires. Many inmates here like the Bridgestone Ultra Heavy Duty tubes. So I thought I might try them.

    However, I have not found that tube in the size of either of the two tires. Both RockyMountainATVMC and Motorcycle-Superstore via chat said that the Bridgestone Ultra Heavy Duty tubes they sell would not fit.

    I must be missing something pretty basic.

    For what size of tubes should I be looking?
    :huh

    Between the heavy D606 tires and Ultra Heavy Duty tubes, that might be a bit much on the 250! I helped my buddy put in Ultra Heavy Duty tube in his DR and wow that was one massive tube and somewhat of a PITA to mount in the tire too! I would have hated to try and do a trail side repair with that tube in there.

    I usually just run "Heavy Duty" tubes and those do just fine.

    With that said as for size, the most important thing is to find an 18" tube for the rear and a 21" tube for the front. Generally, the tube doesn't have to be the exact same size as the tire. Usually a certain tube fits a range of tires in that given diameter.

    What size tubes are you finding?

    I found the stock bridgestone tube to not only fit well in a D606 (90/90-21 is one of its listed sizes if memory serves), but it takes patches well and is durable too.

    The Bridgestone HD tube for the front is Bridgestone Heavy Duty Motorcycle Tube 80/100x21 and the rear is Bridgestone Heavy Duty Motorcycle Tube 110/100x18.

    I hope that is what you asked for... I've had a few.. :freaky

    I've tried Maxxis, Michelin, Kenda, IRC, and Fly Racing tubes. I only use the normal heavy duty ones (because the super heavy duty tubes are a major pain to install)....

    Of all the brands I've used over the past few years, I like the IRC the best. Very rugged yet still easy to install (I use only baby poweder)

    http://www.motorcycle-superstore.co...IRC-TR-4-Heavy-Duty-Tube.aspx?WT.ac=SLIsearch

    110/100-18 will work fine in a Dunlop D606 @ 120/90-18

    Kenda Tuff Tube is also very good, and would be my 2nd choice.

    will a 120/90 - 17 pirelli MT 21 work on the back wheel? I know a 130 works but I can only find a 120 width here in Costa Rica.
    Also, will a 110 width work on the front?
    Crap...In the title, I meant to tell you this is for a WR250X

    Yes, up to 110/70-17 front
    140/70-17 rear so 120 can be used with resultant lower traction, but it looks like you want to go off road if your getting a MT-21.

    I have a question for you. Last spring I cracked/broke/mangled the multi-function display on my WR. It still functioned except for the back light so I just left it and used it as is. I couldn't read it at night but that wasn't a big deal to me. Now in the dampness of winter it's finally quit displaying anything. All the leds still work but the display is kaputski. So my question(s). Should I replace it with a stock display or go with a Trail tech or Vapor tech display? What are the advantages/disadvantages of either? Will a new display show the correct mileage or will it start from 0? If 0 is there a way to program in the mileage? Is there a way to read this info from the broken display?

    That's enough for now :D

    You can program the mileage in when you get a vapor. You will also end up with a more accurate mileage count (eventually) and a more accurate speedometer (it is set based on tire size and within .5 mph of gps on my bike). As an added bonus, sprocket changes will not affect the accuracy of your speedometer since the vapor tachs read speed off the front wheels rotation. The stock one as you know will end up off unless you use a speedohealer to calibrate when you do sprocket changes.

    Thing is, I have heard things about the WR not starting if the stock cluster is removed. See: http://wr250rforum.forumotion.com/t565-trail-tech-vapor-speedometer-tachometer

    Im not sure, but if you need to have the stock cluster, I wouldnt even waste time with a vapor unit.

    It's part of your Fuel Injection computer, and the bike won't run without it. If you buy a used one it will read the mileage that was on the other bike when it was taken off. I don't know if your local Yammi dealer has the ability to go in and manipulate the mileage like car dealers can on newer cars..... they might, but I would guess not.

    Thanks!

    Would having a power commander affect this?

    The power commander won't have any effect on your problem. It just reads the data the computer is already sending out and changes the values per your settings, then sends it back out to the bike.

    But can they? :hmmmmmJust asking, 'cause I had a dealer replace the dash in my 'vette, the new dash read zero miles, I insisted it read the correct miles. They thought too that they could re-program it but found out they could not. They ended up getting another one from GM pre-programed with the right miles.
