    Hey guys,
    I am new to the site, and found this thread. I bought a 1990 dr650s dirt cheap. The crank bearings spin inside the case, so I guess it needs new cases. I was wondering if one of the newer bottom ends would fit 91-92 maybee. I have a couple spoted, but don't want to waste my money. I would even buy a whole motor if the price was right and do a complete swap if it was pretty much bolt up. The current motor has 22,000 miles on it but starts right up. Any help would be greatly appreciated.
    THanks

    Just bought one off a local craigslist seller.
    9000KM on it for $1900 - didn't think to hard - bought it on sight.

    OK - now what...

    the turn signals don't work
    it is hard to start but does
    has big knobbies

    so gotta spend more $ I don't have :-)

    At 6'6" 260lbs - any advice from the knowledgeable folks out there...re: priorities
    1) fix turn signals
    2) slicker tires
    3) ....what next?

    Your questions were left hanging. How did you make out? Got one, runs well and no thanks to my local motorcycle shop.

    I have a 1990 DR650S, I bought it off ebay for $1650, it had a few problems, but for under a hundred bucks in parts from BikeBandit, all is well.

    A few things to answer on the previous posts:
    1. Starting, there is a very specific starting procedure. If cold, Fuel to Prime, Hold the decompression lever and kick through 6 times, relase lever, find TDC, pull lever, let go of lever, lever will stay down. Kick through, lever will pop up. Find TDC if it did not start and repeat. Mine usually starts on the second kick when cold. Turn fuel to on. When the engine is hot, find TDC, pull decompression Lever, kick through, mine always starts on the first kick when Hot. Easy Peasy, right? lol. One thing to remember for easier starts, keep your idle below 1400 RPM, it is a vacuum system and will not start if the idle is higher than 1400 RPM. The unfortune part about below 1400 RPM is that when trail riding, 1400 RPM barely keeps the mortor running, in turn it loves to stall at the most in opportune times, on the trail and the street. Lowing gearing is the key! There is never a need to do 110 MPH on this beast, which mine would do.

    2. Brake Master cyclinder, if your brake keeps sticking, make sure the return hole is clear. I ordered a master cylinder rebuild kit, rebuilt the cylinder, thought I fixed it, discovered at about 30 MPH that I did not. Got it stopped ok, had to bleed the front caliper, ride for a little while till I felt it locking up again, stop, bleed, repeat till home. The return hole is about the size of a #76 drill bit, or a pin from your wife sewing kit. The pin is a bit big, but will work. Problem fixed.

    3. No matter what anyone tells you, it is not a hard core trail bike, it is built like a tank, yes, but that is precisely why it is not a hard core trail bike. It is heavy, and if you do not go to an after market shock, you pogo up and down the trails all day, and lugging all that weight around all day will wear you out. Trust me, I have been there.

    4. Watch the oil cooler, you can and will bend it on the trials, they are expensive to replace, and almost impossible to find used. I bent mine but did not break it, so bent it back and it still work, mostly..

    I'm sure other guys have had some great experiences too, I love the bike, just know it's limitations and ride accordingly, just like every other bike you may have or have had.

    They seem to be significantly different bikes. I really enjoy riding mine, but have never taken it seriously off road. It's just too heavy & I'm not a good enough rider to avoid total exhaustion due to the weight. I love it for riding on the road tho and love the torque. I've got a 40mm pumper carb on mine & it really wakes the bike up throttle-response-wise.

    Mine's always been pretty easy to start. Easier now w/ the pumper, but the process is the same.

    Turn ignition and button to ON
    Turn fuel to ON if it's not.
    Set the choke -- if the engine is cold. Otherwise leave it alone.
    Pull in decompression lever. It should stay in.
    If the lever doesn't stay in, slowly move the kick start til the decomp lever will stay in and allow the kick start to go back to the top.
    Slowly move kickstart downward til the decompression lever clicks back out.
    Allow the kickstart to remove to the upper position.
    Kick the bike over.
    Repeat.

    My bike has started on the 2nd kick approx 85% of the time using the above method.
    10% of the time it's taken 3-4 kicks-- usually if the bike's sat for a few weeks/months.
    The last 5% it's taken more on a very cold day, or when the bike sat all winter & needed fresh gas or the battery was totally flat. It doesn't seem to like starting when the battery's weak... even tho it's a kicker.
    Mine always starte

    Pumper carb from where, and how much fiddling with it did you need to get it to run right?

    I ordered one from these guys $263 shipped. The stock throttle cable fit and worked with some minor fiddling and re-routing. I used big O-rings from a Harbor Freight O-ring kit to shim the carb and adapt it to the intake boot.

    http://www.ebay.com/itm/Mikuni-TM40...Parts_Accessories&hash=item27bfcc823a&vxp=mtr

    It took very little fiddling overall. My bike ran w/ the jetting that comes w/ the carb, but I think I ended-up leaning to 155 or 150 main jet, because it was too rich up top. This is the third bike I've switched over to a pumper carb. I've found that out of the box they usually bog when you open the throttle fast -- until you set the pump so it doesn't squirt gas until somewhere between 1/8 and 1/4 throttle. Delay the squirt a little and the bike runs like a champ. if the squirt comes too soon, it'll bog.

    It makes the bike a lot more fun. Off-idle throttle response is RIGHT NOW. And overall throttle response is greatly improved throughout the rev range.

    I Just bought a 1990 DR650s.....been stored for many years...only has 2,300 miles on her. Orig everything....just going thru it now to get it up to speed...sending off the rear shock for a rebuild....ect....the lack of miles and being moved around in a barn have left it with strange bumps and bruises...dings and a few dents in the tank. Runs like a top and now that I have studied the starting procedure I really like it. Man was that a tuff learning curve on the kick start! Thanks for for all the info you have posted, couldnt have got it started without it!

    Hey Guys, been a lurker for some time now and finally decided to get in on the action. Picked up a 1990 DR650S for 220 bucks last week.... Yes 220 bucks... The catch was it came in a million pieces and hasn't been on the road since 1996. Who ever took it apart actually did a decent job as all the bolts were put back in the proper spots. I started the build 2 days ago and iv'e been insanely busy cleaning everything up. I ordered a bunch of replacement parts as some are worn out more then I would like.... Engine is in great shape although I decided to get a new Cam and rockers as there was some wear from old/low oil and one intake valve has a leak which I will remedy once my gaskets arrive. The problem is I'm waiting for the parts.... the bike is sitting there taunting me.... The bike is identical to Luigi003's pics.

    Bought it for $2000 from a guy in Mississauga. I am the 3rd owner.
    Have put about $2000 in (wife is pleased). The best result was the harley pumper carb.

    Anyways - looking for a mechanically inclined person to fix her up more....part restoration, part repair. Need new rear shock, speedo does not work...want a better seat for longer rides, etc etc.

    In the Aurora area. All suggestions welcomed!
