I got that one from Frantic Cycles Ebay store. Licks & J&P sells them as well but the crank case breather like mine is sold separately.

 

I made this one and the timing cover also the battery cover all from expended metal.cost for all three pieces was 21 bucks.

 

2 i made

 

I need something better too. I dont think whats on it now is very good filtering..Its just a cheezy piece of open cell foam, I didnt realize it but when I traded for the bike. I hope the guy didnt run it like this for too long? I cut a piece out of a filter for a furnace and put it inside the foam one thats on it for a little better protection till I get money for a new setup.

 

really sharp scoot

 

I built my for the exact reason you are talking about (price). I bought a generic air cleaner mounting kit, then bought a double wide air filter that was used on an old FL model (mopst expensive part of the build) I got all the metal from a salvage yard to build the backing plate air filter mount and velocity stack, for the cover I bought 2 old stock Sporty cover off Ebay and welded them together to make a double wide filter cover.
All said and done I had $75 in an air cleaner that works and looks just like one of NHRS forward mount Hurricane jobs for $200.
Been using it for about 5 years now.

 

JRK what seat is that on the bike in your sig? do you have any more closeup pics of your bike? thanks.
