Air filter
« on: 27.07. 2024 03:35 »
Gday Gents,

Does anyone have an elegant solution on how to fit an air cleaner to a later amal or pwk carby on an A7 plunger?

The original damaged 276 is short and takes a rubber boot. Currently running a JRC with a screen to keep the lumps out.

Keeps me awake at night.

cheers

I had very restricted space on my Matchless and found a very neat pancake filter with a rubber boot on e-bay.  I can't speak for how effective it is or the flow, its cheaply made (but it was cheap) but it is better then nothing while I look for a better fix.  Search under "motorcycle air filter" and "40mm air filter" and see what comes up.

G'day Olev.
Do you plan on bush bashing her? I've been running the plunger for 30 years with just a short velocity stack with no ill affects.
A mate has kids that raced minimotos and used a very short cone filter. https://www.ebay.com.au/itm/334396044300

My PWK came with a nice little filter - fits a treat. Mind you it's a SA frame 650, not plunger 500, maybe the space available is different.

Just had a quick look. From frame down tube to carb (932) mouth is about 45mm.

An alternative is a silicone tube 90 right angle then a cone filter.  The bend should just fit in 45mm.

Or you could use an original air filter (look in For Sale!)
