Frame Bungs.

  1. I’m in the process of building a 900ss cafe racer. I’m looking for some alloy frame bungs but can’t find any for a 93 SS. I’ve found some for the early carb monster 600,750,900. Does anybody know if the engine mount tubes are the same diameter? Ive included a couple of pics as I know everyone loves pics!

  2. I’ve got both Hicksy, I’ll measure them tomorrow and let you know.
     
  3. Thanks Mark. Appreciate it.
     
  4. Hicksy, on my 1996 M900 the rear frame bung tube ID is 20mm, the front one is ID 21mm, I can’t measure the ones on my 1991 900ss as someone in the dim and distant past appears to have glued them in!.
    ID = Internal Diameter of the tube.

  5. Fronts 21, rears 20 on my frame, Unknown’s age or model, but the bike is a 900 as it sits. They look the same as my old 750 and 400 if I’m honest.
     
  6. Thanks for this. Same tube size between the models then.
     
  7. Try buzzer on here, he’s a fabricator he made some bungs for his own project. Maybe he’d be willing to make some for a fee obvs he could maybe run a batch up? I’d be up for some on my old knackered Monster. @buzzer would you be willing and able?
