Another air filter turned toolbox
« on: February 16, 2012, 01:16:46 AM »
I wanted to modify the air intake so I could use the toolbox.  I had read that people had worse mileage due to turbulence if they just put the cone on the throttle body.

So.  I meandered about the local auto parts store for a radiator hose that would work and was able to put together a filter setup that fits inside of the bike without needing to remove any parts!  And it cost less than $40

I used a:

48 mm emgo tapered air filter
2 1/2" PVC or ABS pipe (used as a coupler for the filter to radiator hose)
Random Radiator hose that had the right bends and size (Gates 21064, from a Ford Ecoline according to Rock Auto)
3 hose clamps.

I had to move the starter coil up on top of the mount and over to the right had side but it still fits neatly under the seat.  That kind of required mangling the mount, but it should bend back (I never really liked that coil anyway)  I moved the sensor (what I think is the rollover sensor) to where the starter coil was.  Moved some of the wiring looms to make room and brought radiator hose out and turned 90 and mounted the filter behind the battery box which should keep it free from water hitting it directly.

Getting in there also gave me the chance to put hose pieces around the wear points on a bunch of wires.  I'll keep an eye on my mileage and report back if this gained or lost mileage.

Enjoy the pictures below.

I don't pretend to be an expert, but i think any problems people have had fitting a filter direct to the throttle body would be due to the shortened intake length than turbulence.

Interested to hear how this turns out

So I took the bike for afew rides, none far enough to require a fill up.

The most noticable change is the amount of noise coming from the intake.  When I really get on it I think the intake is louder than the exhaust.  Almost a popping noise, probably because it's taking 1/2 liter breaths.

There may be a slight increase in responsiveness, but I also gained a tool box.

I'll report back on mileage later.  Was averaging 63 pretty consistently before.

I mounted mine right to the throttle body.  Isn't that sound just glorious?  With the close mounting I had a big dip in MPG so I'm back to stock right now.  I'm curious to see how your mileage fares.

I side mounted a universal air filter with a piece of plumbing tube.

Check it out.
