I am having trouble fitting the filters on my CJ360. It is a bit of a frankenstein bike : engine from a CJ360 (origin unknown), frame is a 1978 CJ250T. So far the only difference I found is the length of the drivechain. However, there were no filters with the bike when I bought it, and I got hold of CJ250 filters and boxes, year unknown. I have trouble fitting these boxes, and the rubber between carb and airbox really distorts when I force it to fit. Is there a difference in the construction of CJ250 filters between years? The frame and the airboxes are both from a CJ250, but the date for the airboxes is unknown. It really looks like the airfilters should be way further back than they are now, any clues I am missing?

I didn't actually look - it was informational for you to do the comparison, wasn't sure if you knew of this resource. Don't know what else to tell you, since we didn't get the CJ250 here

Thanks, but I’ve been studying CMSNL schematics for a long time. I did notice that they now have the proper bolts to mount everything, will probably order those.

And so many times I post that cmsnl.com link and usually people aren't aware of the available resource - and often still don't use it but come back to ask more questions about parts when it's all out there if you do a little due diligence. Glad you're aware, we never know until we ask

Carbs are same on CJ250 and CJ360 so I don't know why filters would be different? . Swing arm is longer on CJ than CB so needs longer drive chain.Chain length may be different due to smaller rear sprocket on 250 although British ones 'always' used 17/34 same as the CB360

I have a set of boxes and covers for a cj360
From the sounds of it they're the same as yours / 250 model. I can take measurements if you want, or sell them to you for $20 plus shipping.
If you want measurments, just let me know from where to where.

Thanks, that woudl be very helpful! I would need measurements front to back (how deep are they), from mounting point to mounting point, and specifically the position of the mounting points compared to thickness. Perhaps a few pics would be helpful too.
