So theres no mods to do on a Performance Machines Fast Air intake since it has internal breathers beneath the plate correct?

 

Update:

I was not happy with how my breather bypass was fitting together. I went and bought 2 90 AN 6 to 1/8" NPT fittings. My plan was to drill the holes at 90 degrees and use the rest of the set up I posted earlier. 1 of the issues with this is the holes have to be drilled higher up so you have clearance to screw the fittings in. The 2nd issue is the spacing between the 2 fittings was to wide for the rest of my set up. I will plug the holes and go back to my original set up.

What I have learned is 45 degree AN to 1/8" NPT might be the best for the filter and tubing I put together. I may buy a new back plate and 2 of the 45 degree fittings and have a machine shop do the drilling and tapping so that every thing lines up better. This should put the spacing just right for the filter and tubing I used.

 

Thanks for the write up, might have to do that on my scooter.

 

Had my indy do mine yesterday. Good thing as it is snowing here in the D FW area right now. Mine was easy to do. I have the S&S teardrop high flow that uses banjo fittings. In the 60 some mile ride back to the house on a combination of both interstate and county back roads my sop feeling is that the engine pulls better not having all that crap going back into the throttle body.

 

If you run some of chevrons " Techron Fuel injector cleaner (using their concentrated version) in the fuel tank thru the motor 1x or 2x yrly depending on mile ridden it does a good job of not only cleaning fuel injectors or a carb but it also cleans carbon etc from the intake valves , pistons ,and combustion chambers in general too.

Unfortunately doing that wont address the main issue of fouling the air filter ,intake ,or throttle body with oil etc .

I i am seeing the pics correctly its looks as though the original poster of this thread didnt install small cleanable K&N type breather filters which i would do if it was my bike.

==========================================

 

Installed the breather back on the bike. I am already planning a new revision to this. I finally found a breather with an 1/8" FNPT.





Front View The breather is not centered but I will fix that with the next rev.




Throttle body side:












I think you could easily use AN4 fittings and hose and have less worries about clearance

 

Looks nice bro! Well done!
Care to share your source for the filter?

 

I got mine here

http://www.motosport.com/cruiser/Bik...kcase-Breather

But you can also find them on Amazon and eBay but the prices very from 8.99 to 30+

 

Thanks!
Did you drill and tap 1/8 npt threads in the opposite end to make the filter duel inlet? All I am finding are threaded on 1 side only & I am questioning if the opposite end is thick enough to tap threads in.

 

The threaded one will be for rev 2. The one I used currently is the dual inlet for 3/8: hose.
