One of the many mysteries I have seen on this site.
I have questioned it since I burnt the second tank on my 07.
All but 7000 now and the best I have seen is 42.9. I average 39.9 consistent. Now I do ride a lot in winter and my bike does get the crap they call gas here in winter PA.
I do have the side wings out for about 4000 of those miles. But I only raise my -6" shield enough to get the wind over my helmet, never look through it, or is it in my sight line.
I do ride a lot of slab and I am a solid 80 MPH or better driver. I have suffered the pain of setting the cruise at 68, and it did not improve enough to make the computer change a point!
It really is driving habit, the ratio change, and I would assume the 05 and better are set richer as I assumed they achieved the increase by compression.
Which would call for a bit richer fuel map. Tire pressure for sure.
Has anyone cleaned up their heads, or are they pretty clean and flow well?
Anyone seen an increase with an aftermarket exhaust? Other then tone/sound?
Anyone ever seen or heard if the Throttle Body is set up well stock, and ever needs synced, or any attention?
I am still one of the happiest guys alive having all the fun I have, and getting 40 MPG doing it. While I would love 50, 40 will do, well at least until it hits $5.00 a gallon
