961 air filter

The BMC will fit all, and is actually now standard fitment on the brummy built bikes. It's a very nicely made filter and if correctly maintained, will last you a life time.

Thanks Stu - you’ve made me feel a right muppet! I have spares!!

What process do you use to clean the BMC?

Hi Stu , I have a BMC filter and it was the same length as my original norton filter. Is the Domi filter shorter or no ?

Stu Bodycote said:

Yes, it's longer than the early revision....but it's a perfect fit, gives a bigger filtration area and is just MUCH better quality than the original shite.
I sell the BMC at just under £90.
The most common model I fit them into is the Dominator, due to their original filters being contaminated by a wet sump situation. The Commandos don't tend to soak their airfilters in that same situation.
The fanciest 961 filter was the final revision. It had a similar filter medium to the bmc albeit dry, with black anodised ends, with Norton engraved on one end. Those were produced by Micromesh...and they actually own the rights to the design. They'd happily make them for me, but the MOQ meant it would have cost me over £5k. They were that nicely made, that my apprentice at Norton was cutting the end caps with the Norton engraving off the old filters, to make a coaster set

Ok I’m glad there’s something better. I removed the filter from the Donnie and scratching my head how they got it to fit in the first place. The lip diameter doesn’t fit right on the air-box opening.

Cant post pics atm as I'm out of the country but simply the diameter of the filter bottom is shorter than the groove that it sits in the airbox. There's no way the filter is secured 360 deg by cover. I actually dont know how they put these on in the factory but there's plenty signs of silicone being involved

Do you mean there are gaps or opens places around the perimeter of the seal ?
