Does anyone have any tips on how to get the air box back on??

I've tried putting some oil around the seal but it's not helped.

My only other thought is try a bit of heat on the rubbers.

  • I find grease always works for me. If you intent to use heat, be careful the rubbers dont go out of shape. Being old, they might not return to their original shape.

  • I'll try it tomorrow.


  • Take the filter out and push it on from the inside

  • Don't think that's possible with the L air box!

  • If it will not slip on with some grease, look at the rubbers. They might have gone hard and need to be replaced.

  • Hahaha I've been having the exact same problem with my J model, rubbers are reasonably soft and have shape, tried grease oil, rocking it, hitting it with a mallet etc and still cannot get it to fit!

  • Glad it's not just me.

  • Hey Nathan I finally managed to get my airbox back on. I loosened the carbs a bit so they could move, put a healthy dose of grease on the carbies and rubbers, then finally got a heat gun and applied even heat to the airbox rubbers for a good amount of time til they were hot and maluable. Then quickly positioned the airbox, and pressed it down and used a mallet to whack it from the back to slip it on.

  • other way to soften them is soak in Paraffin or Kerosene for a few hours, that can soften them up too

  • Heat gun/ hair dryer takes like 5 mins to heat then up enough to make them soft and maluable :)

  • Gabriel Olszewski. I left mine in the house overnight by a radiator. This made the rubbers soften up.

    I took the rubber scoop out of the frame and fitted it to the airbox, then fed that through the frame. Seated the airbox in place then a couple of gentle taps with my hands and it seated lovely.
