just filled up after do the airbox mod and I got my highest mpg yet... each time I have fill up the mpg have increased but today I when from 42 to 46! so not only was the airbox mod free it appears to have increased my mpg too
rode into work... it was 31 when I left in the morning (burrrr) and 55 on the way home... stopped at Cycle Gear for some chain lube (I had been hearing a rattle on decel) applied the chain lube when I got home and then went to the gym and didnt notice and more rattle.
last week I bought some reflective and glow in the dark vinyl.
Since I did the FE mod and no longer have the side reflector I thought I would make something with the reflective vinyl, this is what I came up with...
I think you are talking about this one:

and I agree with JT do the exhaust tip mod, which I think is the one posted above by kevin8198
