Air Filter

[bullethead]

Just bodged together an induction style filter and thought i'd share the pics. I got both filters of fleabay the smaller was nicked off my scooter when I realised I needed something for the secondary air pump. All in £50.

Does it run any better, or just sounds better?

this was the main filter I paid £38 its got a 92mm inlet
As for the small filter its a 28mm inlet 90degree bend filter for a scooter, needs a 90 degree bend otherwise it wont fit onto the inlet on the secondary air pump.

this aint the 1 I bought but you get the idea this is the seller I bought mine off though.
I'll get some more pics and try to do a how to but its 1 10mm bolt and disconnect 3 hoses, no tools required they all pull off. There is a small vacuum hose that opens the inlet valve in the airbox which becomes redundant.
Pics to follow soon.

Don't know what to suggest....You could try google for scooter spares in the U.S .The filter I used is made by tnt and has an inlet of 28mm, there must be someone near you selling something similar???

yes finaly. so 92mm inlet on the large filter and a small "breather filter" for the inlet valve. Some close up shots of that will be nice. any other plugs or things needed?
