GraydonEng., Thanks!
Craig Vetter's Honda Helix has gotten as good as 104 mpg but he added on a lot of streamlined body parts and had to have new taller geaing fabricated to do it. Its tough with bikes you can't easily gear taller . Streamlining helps some but I think its the synergy between reducing your air darg and increasing your engine efficiency that makes for the big changes.

I like reading how well you guys are doing on your bikes. Lot of great ideas with deflectors and small aero mods that don't take away from the experience or look. It all makes me want to follow suit with something I consider a toy and not really practical in my location due to traffic. I don't do the long haul trips just short runs here and there.

Now I have been considering going from a 28 tooth front sprocket on my bike up to a 32 tooth in hopes of getting the Harley into the 70mpg range. it shows a 10mph. difference on the speedo @70mph(easily re calibrated). with this swap easy change and cheap for the sprocket about $100 only issue I have I lose some of the fun factor. But I think it may be good for me to keep the front wheel on the ground. A few guys have figured a 28 to 29 tooth swap is 3.5% and a 28 to 30 is 7% with this I would hope that a 28 to 32 would give me 10% difference darn close to 70mph.

They run windshields and bags and junk like that I run tucked low with shortened low rise bars plus most of the guys I have been following have 50+ lbs. on me so I have that advantage as well. I think I will hold off until I pick up a TC88 so I can reprogram speedo, data log, change limiter, and a bunch of other cool stuff but that is a little pricey right now at $300 making this easy mod more of an investment. looking forward to seeing improvements

thanks NHRABill,
I love motorcycling but have often used my bikes for commuting to work and running errands. Now that i'm retired from full-time employment, I ride more that I drive. Here in the SF Bay Area we have some of the worst traffic congestion in the USA. Riding a motrocycle through stopped traffic ( lane splitting is legal in CA) saves huge amounts of time. WIth the rise in gas prices, this may be the time when we see 2 and 3 wheelers began to become more common as transportation as they are in Asia and Europe. Jump in and catch the wave.

Finally backed up my 104 mpg tank with a 90 mpg tankfill. Also my project was mentioned on the Vetter website , check it out 22011 Vetter Streamliner-Chap 56
