Post by: Moorey on March 12, 2023, 03:35:48 PM
Does anyone have or know of a air cleaner box seal for the two halves of the box for a 750f1 they a different to the K series Or any suitable seal material to make one out of as mine seems to have turned into jelly.

I've nothing but if I got desperate, I'd be looking at sliding door seals or similar to maybe modify. Getting something that shape might be tricky though.

 I'm getting fed up with looking at seal profiles. It could end up with me making one with black Sikaflex  ;D

Getting closer now I know the profile description  Small Square U Seal. Now seeking one in a suitable material.

When we were in rented housing after our house fire (for 8 months)one of our puppies ate part of the double glazing front door seal - might be worth looking at some of the frame/window seals.

I managed to find some online that fitted perfectly.

Looks the same U section as the 750k but, can not find a part number for the 750F1 to compare.
 I could never find a U section rubber from any manufacture when i was looking to replace a 750K one. Ended up buying a Honda one  ;)

No it's not listed as a separate item. I have found some rubber section that looks quite promising and may need a trim with a blade but I need to measure up properly as the existing bit of seal is quite swollen. The carbs have been passing over the last couple of weeks and filled the air box with fuel knackering the seal and air  filter.

Here you go mate, as discussed. Very soft rubber and this a new one for a CB750K.

I was searching through crash helmet rubber trim type things to find alternative.  Types like Simpson have used this around eye apeture as example.
