I only put one long tip on my 85 and that was a year ago when I bought it. It was running good, I thought, but I only got about 23 MPG at about 70 mph. Then this fall Bajaman helped me adjust the valves, (it really works good with two guys) and what I thought was a good running 617T, became awesome. And I know my fuel mileage increased a little though at that time we were fast going into winter. I think I can safely say I could get 24/25 at 70 mph cruise now. Not real good, but for 8 months now I will run cold, clean grease! If you run cold, clean grease you worry about filters, not mpg.
