After reading the service manual I found the minimum octane rating is 87 with ethanol, I've been using 91-93. So I figured I would give it a try and see what 89 with 10% ethanol does.

Notes: Just got the bike out for the summer, had to put a new battery in it because it died over the winter. I've been using it primarily at night, so there are a lot of cold starts in the upper 40's bringing the MPG's down.

Weather has been getting colder. Highs in the 70's and lows at night in the 40's - 50's. So I've had to let it warm up for a couple of seconds before I can take off. I'm guessing that's the main reason it's dropped just a bit.

Weather has been rather warm. I also did several longer trips this tank (20-25miles around town), so I think that helped because it really had time to warm up.

Tried a little engine off coasting this tank. Gotta be careful at night because the lights dim really bad after about 15-20secs. But it looks like it paid off because I beat my 40MPG's goal.

Weather this tank was hot in the 80's and 90's which I'm sure also helped.

The bikes been sitting for a while because of the cold weather. Plus I think I may have topped it off a little higher then normal. But still not bad considering it's all city driving.

Would have been higher. But this is my delayed getting the bike ready for winter tank. So after sitting for a couple of weeks with temps dropping to as low as 5F it needed a good 5-7min to warm up before I could take it to the gas station.

Highest tank to date. I think I finally got the carbs cleaned out so I've been running lower idle RPMs(about 1100) as opposed to when it was having problems(about 1400). Also seems to do better at lower RPMs when cruising at 35mph so I started running a higher gear. Went from about 4500rpm at 35mph down to 3500rpm. Seems to have made a big difference.

Tried some engine off coasting this tank. Didn't seem to help much. We've had a good amount of rain so I haven't been riding it as much. So I've been wondering how much gas I loose having the bike sitting out in the sun (evaporation).
