    1992 DR250s carburetor

    You’re correct. It’s a cv carb a mikuni BST31. Which happens to be a purple unicorn when it comes to carburetors. I’ve read about switching th throttle and adding a pumper carb, but heard that’s effected the idle and what not. I’ve also read about using the bst33 from the dr350’s, but that is apparently too much carb for the bike. I’m really looking for the exact same carburetor. Or someone who can rebuild it, or someone who has replaced the carb on their 250 and has had success with something else

    1992 DR250s carburetor

    I need a to buy a new carburetor, my DR was left in a barn with the air filter cover off and some mice made it into the carb and ruined it. I’ve gone to 3 shops to try and have it rebuilt with no success. And I can’t seem to find a replacement anywhere. It’s the TM33 vacuum carb I believe. I need to get back riding and love this bike I would really like to get it running again. All the parts I have. I took the plastic top off and the rubber flange inside, as well as the spring, needle jet. Also the bowl and floats and soaked it in cleaner. Nothing seems to be working. I would like to just pay someone to get it running right or ideally just buy a new one that isn’t a pumper carb. Thanks for your time

    1992 DR250 Carb

    Just curious how difficult is it to convert the carb? Do you have a intake manifold?

    1992 DR250S Engine Trouble Please Help!

    I have a 1992 DR250S and basically it has been running like a top the past two weeks, but today it has been running like normal until I get on the main road and once I get to cruising in 6th gear the engine bogs out and dies. Once I sit for a few minutes and Let the engine cool a few degrees and pump gas into it by holding the decompression lever and kicking it a few times with the kill switch off it will start up, and run, until the engine is warm and then it dies again. There was an exhaust leak coming out of the cylinder so I fixed that and found the decompression cable was frayed where it attaches to the engine.

    '92 DR250S Big Bore Kit Questions

    I recently Aquired a 1992 DR250S, in pretty rough shape, (all blinkers and mirrors broke off, graphics peeling, carbureator clogged with gelled-up gas) but then again, it only had 600 miles on it when I began working on it in May. It now has 2,500 miles, and i've given it a complete make-over body wise. And internally it's running like a top. Now I've decided I want more power and instead of buying a bigger bike or swapping out the motor with a 350, Im going to purchase a big bore kit I think the way I plan on going is purchasing the dr250-340 BBK through Thumperracing.com, but I would like to give my bike as much power as possible. I know that the 1992 DR 250 and DR350 are almost the exact size besides the cylinder size and some other internal dimensions, but the engine block and external engine size are the same. Also, Ive noticed that Thumper Racing sells a DR350-441 BBK... So the big question is, What's stopping me from putting the 441cc BBK On to my DR250?? I'm sure I'll have to modify some other things, but theoretically, it should work, right? Right now I have a modified Intake, and I'm in the process of purchasing a FMF Powercore 4 pipe to eliminate the restrictive air flow, I'm thinking I'll probably need to get a new carbureator, but why don't I ever hear of people putting the 441 kit on a 250?? Thanks! Red 1992 DR250S

    1992 DR250, more speed?

    How much faster can I go just by changing the sprockets?

    1992 DR250, more speed?

    My father bought a new DR250 in 1992, the same year I was born. He did very minimal riding and kept it at our vacation home 4 hours away. About a month ago I decided to take interest and bring it home. It hasnt been rode in 5 years or so, and was not running when I brought it to my house. After going through it, and taking apart the carb that had an inch of yellow gelled-up gas in the bottom of it, I cleaned the carbeurator and finally got it running. Believe it or not this bike had less than 700 miles on it when I took it home ( I just today broke 2,000 miles) I am absolutely in love with this motercycle! I cleaned it all up, put a 4 gallon Acerbis gas tank on it (I have the stock gas tank for sale) and now i am in the process of painting the white plastics yellow. When I first started riding the fastest I could go was around 65-70 MPH. Now I'm cruising at around 75 which is also top speed. How can I increase this top speed as much as possible, I would put a 350 engine in it, but there is such low miles I think that would be stupid. I would like to be able to go around 90-95 Mph.. Oh and also take into account that when I'm in 6th gear on the highway, I lay all the way down on the bike with my helmet under the front headlight plastics and I put my feet back on the passenger pegs. The aerodynamic effect easily gives me an extra 10mph top speed.
