Carb Help

[Mick Milakovic]

I have two bings off my '75 250 project.  One has a stripped out idle screw hole, the other has a broken off (and locked in) pilot jet.  I'd like to have a bing, of course, but will settle for a Mikuni.  Anybody want to trade, or sell a carb?

Mick, Do you think that a Bing body off of a 73 250 would work? I have one that I will send you if it will. It ain't pretty, but I think it is usable. Dennis D

Thanks Dennis, but I don't know the answer to that question.  Does anybody know if the 75 and 73 motors used the same carb size?

[Mick Milakovic]

Measured my bing last night, but still not sure what size it is.  It measured 1-9/16" in diameter, or 4 cm.  My ruler didn't have mm on it.  Does anyone know what size that is?

Mick,
  I don't know what part you are measuring, but 4cm = 40mm.  Hope this helps.

Ron, I just looked down the bore of the carb and measured what I thought was the inside diameter.  40 mm sounds too big for a 250. How should it be done?

Mick  If it's a Bing, it should have the carb size stamped on the body.  Should be a 36mm if stock.  Good Luck!

Mick, the plate on the carb reads: 2/36/102 Why don't you send me your address and I will ship it to you Monday. Dennis D

[Mick Milakovic]

Thanks Dennis, that's what the stamping on my carbs read, also.  I'll contact you off topic.
