What's the best way to fit the air box as it's clearly a tight squeeze & difficult to engage all four inlets.
I have a small cycle inner tube to fit inside to help keep the box from collapsing but it turning into a bit of a nightmare job.
I've already removed the battery & rear mudguard to get the battery frame & air cleaner  to improve finger access !

Update I've fitted the box but the middle two rubbers are only a third of the way on whilst cylinder 1 & 4 are fully fitted - this will have to do for now so I can get her running. I guess the air box has just deformed with age so might need replacement when I do the full rebuild.

You might want to consider buying new rubbers, age can make them brittle and it doesn't help them go on.

Thats because you have PD carbs(550K3) and the rubbers DS sells are for the older carbs and dont fit

Get a wooden stick or dowel long enough to reach through the large hole in the filter box and use it to push the air box and rubbers from inside.

Thanks I'll try that when I have fitted the new fuel line.
When I do the full strip down I also intend to change the front  right hand stud to a nut & bolt on the battery box fitting. That will make fitting the air filter/battery box so much easier.

In my case as I am over 72 my skin is thinning also being  on Aspirin etc my skin just bruises and bleeds at the first opportunity. That said a good fit is worth the discomfort afterwards!!
