Airbox Mods

Post by Beef »

Been trying to find info on airbox mods - found a link to the Superhawk forum that
Had the filter mounted in the lid - I like that idea. There was also a reference to a mod done by Roger Ditchfield but I can’t find anything here! Can anyone point me int he right direction?

The air filter in the lid MOD means cutting away most of the lid, you just keep the lip around the edge with the fixing holes in it of the lid. So basically the air filter top is open to the air.

IIRC Micky (mik_str) runs one on his very modified Storm,

that which you speak of, Chris, is Roger`s set-up (trim lid and leave 10mm ring all around to keep the filter in place). My set-up is different, as I removed the filter panel from the inside and mounted the filter element into the actual lid (thereby increasing internal volume and clearance above the stacks, for better airflow).

As for info, I posted a lot of it here and on the superhawkforum... one need only search for it

Is there a basic mod that can be done to an otherwise stock engine? I remember reading somewhere you trim a certain part and it smooths out the bottom end but now i cant find it. ...or maybe it came to me in an opium dream.. not sure.

Regarding Roger lidless airbox, it has potential of 5-7 bhp on rear wheel with stage1 engine (higher cr, more agressive cams, etc ...). But on std engine, there will be lot of headache only.

For std engine, I would clear the tank for crankcase breathers and use external pod filters, try to use different filters (incl removing traverse part in upper lid), and maybe experiment with different stacks.

There is added benefit that on cleared lower airbox it is much easier to work on carbs.

Cannot comment filter in lid mod on std engine, somebody have to try.

Stock, the filter is sandwiched between the base & lid of the airbox.

Thanks, I may look at fitting the K&N filter I have in the lid (& sealing original air inlet)so that the whole airbox is filtered air...... but if she runs really well tomorrow- I may do nothing 😆

What would you guys say about this air filter? The whole thing is filter area as opposed to the small rectangle you normally get.

The filter area on a standard one causes no restrictions so increasing it makes no difference.
It's not falling off, it's an upgrade opportunity.
