    Well I think I will have to look else where cause the dr350 spring is 2.25 id at the top and 2 id at the bottom and the 650 spring is a inch shorter than my 350 spring.

    The correct length spoke will be longer than the distance from the hub spoke hole to the rim spoke hole.
    That means when you are starting to screw the spoke nipple on, the nipple will not be through the rim much, if any at all.
    Sometimes you have to grind the end of the spoke off so it doesn't puncture the tube.

    Sounds like you are using the short spoke on the long spoke side which won't work. :huh

    11,000 miles of fast highway so far. Only issue is a very, very small oil leak; probably from the tensioner. haven't had the time to completely diagnose. It's not enough to even leave a spot on the ground.

    No issues with mine. Getting out to a safe lane on the NYS thruway requires a great deal of acceleration.:eek1 Staying ahead of idiots who try to tailgate keeps me moving between 80 and 90 mph on I287. I tend to ride fairly aggressively and always downshift while braking. If braking hard, I downshift very quickly. No issues.
    :clap

    Besides, riding it hard is a lot of fun.

    So I'm attempting the beginning maintenance on my DR, and I managed to change the handlebars successfully, so go me. Although I did undo things that didn't need undoing, like the clutch and the box next to the throttle...whatevs, it still ran fine after than particular mod.

    Yesterday I tackled the gas tank, and put an IMS on it. After much frustration, I found I could only' keep the thing running when the vent line from the gas cap to the ? was not on it at all, otherwise it would die as if it ran out of gas. I figured, ok, I can deal w/ this temporarily in the winter before finding a better system, and it ran fine on the round-the neighborhood test drive I took it on.

    Fast forward to this morning, and I can't get the thing to stay running. It starts fine, idles ok (seems to idle fine only when throttle is fully open), and then I take it as far as the end of the driveway before it stalls out. Generally in first gear, as soon as I try to get it to move further, it just dies. There's gas in it, the tube from the petcock to whatever is 4 inches to the right of the petcock seems clamped on fine, no leakage or anything. I've tried putting the vent tube from the gas cap back on, no dice. So why in the hell is my engine dying w/in <2 min of running? I was so proud until this morning...

    In short, at the moment I'm an ignorant noob and a dumb brute. HULK ANGRY

    Your descriptions are great! :rofl
    Since you know what the petcock is, did you reuse the original petcock, or install a new one?
    Also, attempt to blow through the gas cap tube with your mouth and see if you are able to, and let us know.

    One more thing, idling and the throttle being fully open simultaneously is impossible. Full throttle means maximum acceleration. Idle means just sitting there on the kickstand running without you touching it.

    How much fuel in the tank? IMS petcock or stock?

    Well, that's solved the confusion. :wink: I measured the old one with the new one and it does seem longer. I was starting to think, if I had to do this on the side of the ride for whatever reason, it would be very painful.

    I will source out some disc side spokes. Its raining where I am and nothing better to do then to put a tyre and wheel back on! :1drink Thanks to both and another learning experience for the mighty DR :lol3

    IMS Petcock. Should I put on the stock?
    Perhaps by open throttle I mean open choke? That sounds more correct

    Oh, and vent gas cap tube is fully blow-throughable. Fuel is about 2 gallons.

    To throttle means (from Webster's):

    a (1) : to compress the throat of : choke (2) : to kill by such action
    b : to prevent or check expression or activity of : suppress
    throttle creativity>
    2
    a : to decrease the flow of (as steam or fuel to an engine) by a valve
    b : to regulate and especially to reduce the speed of (as an engine) by such means
    c : to vary the thrust of (a rocket engine) during flight

    intransitive verb
    : to throttle something (as an engine) &#8212;usually used with back or down <the pilot="" <i="">throttled back

    Therefore full throttle means that the throttle is fully closed. I recommend the use of the phrase "wide open throttle" to indicate that the throttle is open 100% of the way. Similarly saying "1/4 throttle" (for example) means that the throttle is open 3/4 of the way, so a more proper way to say that the throttle is open 25% of the way would be to say "1/4 opening". The only time this makes no difference is with 50% opening, where it obviously doesn't matter whether you say "1/2 throttle" or "1/2 opening".

    The IMS petcock is fine. It sounds like the bike is surely starving for fuel.

    As long as the bike was running fine prior to your IMS tank installation, there are only a few things to look at:

    1. Make sure the fuel line from the tank to the carb is not kinked.
    2. There is a tiny filter in the carb inlet (carb side of fuel line) that might be clogged.
    3. Make sure the petcock is in "reserve" or "on". I think the directions are different than the stock petcock.
    4. There might be vapor lock in the fuel line. (An air bubble if it has a high area).
    5. There was a vacuum line going from the stock tank's petcock to the carb. The nipple on the carb where it attached needs to be capped.
    6. Put more fuel in the tank?

    Anyone know if the RM/RMZ foot pegs fit the DR650? If so, what years?

    Out of curiosity do you have the tank vent tub attached to the vacuum port on the carb?

    There is a breather line from the carb on the right side which if pinched by the installation of your new tank won't allow the motor to run for long. I forget exactly which line it is but mine did that once a few years back. Take you tank off and see if it runs. If it does watch where it might be pinching a line when put back on.

    I LOVE the diecel popping.

    i would pay good money to make a motorcycle sound like a rig.

    anytime i can imitate a vehicle that could kill someone in a car and make them think twice about coming into my lane.

    thats a +1 in my eye's :evil

    The above is very good advice. Also make sure of your fuel hose routing ... and sometimes in line filters can create flow problems.
    fuel does not like to run UP HILL. Gravity is your friend ... and it's why most riders with the IMS tank ROTATE the metal fuel tube either to the 3 or 9 o'clock position.

    Also, just for laughs, drain your float bowl.

    A Rig?
    Fact. Loud pipes will never save you. They simply piss people off and make them hate motorcyclists and lumping us all in with the neanderthal "Bikers" Open Pipe Knuckleheads. I'm never a BIKER ... I'm a motorcyclist. Loud pipes guarantee that anytime that motorist ever gets a chance to vote on anything about bikes ... it will be a BIG NO.

    I like a bit of growl ... within reason. The GSXR pipe is about my limit. My old FMF Q2 was too loud for me and brought unwanted Police attention in town. After all ... how am supposed to get away with jumping curbs and riding up stairs of industrial buildings if the cops can hear me two blocks away? :lol3 With a loud pipe I'd never get away. :D

    "Throttle" can be either a noun or a verb, depending if one is talking about the device or the action.
