I owned two 1500s, a '94SE and a '98SE.
both of them averaged 33 mpg for me, both had a Tulsa Tall windshield which is the primary reason for the low mpg..... the 2nd reason is that I have always lived in the western states where it is 100+ miles in a ruler straight line to the next object to be seen.
So, the throttle is up against the peg going there.
My Wing is the 2000SE. What is odd, a sticker on one of the covers says to use 91 octane. Reading threads this bike can use the lowest grade 87 without issues, which I have. Last week I tried the 15% ethanol, no issues, but this is summertime.
For giggles (a few times) 100 Octane. This bike seems perkiest around 93 Octane, any higher there is no difference.
Makes me wonder what this SE has for a motor... but I am sure its normal. Nor have I looked up the Vin for info, yet.
So, fuel mpgs.
I too switched to the Tulsa Tall. I enjoy the scenery too much to ride fast, if I do not have to. I am steadily getting 42-ish, a few times 46 & 47 but those were windy days. On those windy days I try to ride with and against for comfort. Side winds, I earnestly look for tree lined roads.
Here is that sticker. (below)
Also it does say RON not Octane. Just a habit.
Basically speaking, the higher Octa, uh, RON the more power the motor produces. As a side note, I do get a little better fuel mileage.
I am not interested in debating this, IT IS WHAT IT IS.
