    Carburetor swap

    My1979 rm250 carburetor was designed to have no idle and that's a pain. The carb is a mikuni vm36. If I can find another mikuni 36 can I swap it and of course I would change the jetting to match the other carb...or does someone have another idea? Thanks

    turns out that my pilot jet should be a #60 and I have for a main jet #280. For the main jet I have the option of #260, 270, 280, 300, and a 310. It being a pig on fuel would it be okay to go down to a 260 for the main jet....also does anyone have a trick on how to re seized pilot jet.? Mine will not come. thanks

    swing arm pivot bolt

    how tight should the pivot bolt be when you slide it inside the bushing?? The bushing goes in tight inside the bearing...no play in that area, only play is inside the bushing that's why I'm thinking that the pivot bolt I have is not the correct one.. Anybody else have a "79 rm250 that could measure the length and width of the bolt.? thanks

    swing arm pivot bolt

    lol...sorry about that its a 1979 Suzuki rm250...I must have been really tired?!
  5. After a ride the other day I noticed some side to side play in my swing arm. After taking out the swing arm, I inspected the needle bearing and they are fine but I noticed some play with the pivot bolt when its inside the spacer(part number 5 on bikebandit diagram). Getting the spacer does not seem to be a problem, I can get a complete kit spacers and bearings but I would like to replace the pivot bolt. Would anyone know what the size is...diameter and length, the reason I'm asking is that I wonder if I have the correct one. thanks for the help.

    I find that my '79 rm250 runs a little rough at slow speed and the one thing I've never done is check the jetting in the carb. Would someone have the jet sizes and also what position should the clip be on the main jet. thanks
