Regular. Our engines are low compression and does not need high octane.

Unless you bored it out.

Regular works fine in my bike but I did start buying a better brand of gasoline and everything runs better from the lawn mower to the car.

Regular for sure, our engines are made for lower octane ratings.

Regular and regular. Cheap gas for a cheap bike! Saves money for other purposes!

Ethanol free regular from the farmer's co-op if I remember to gas it up at home. Otherwise whatever is the cheapest regular I can find. Yesterdays tank was 1.568 gallons, a very low 49.107mpg. Won't be using that station again, I usually am getting around 58.6mpg on modern gas, 68.5mpg on ethanol free...

A few words of advice -- There is no performance gain with higher octane than what your bike NEEDS. Our compression is so low that 87 octane is really a tad high for it. 87 is all you need (or 85 at high altitudes).

Thanks guys, I just wasnt too sure being that my brother and friend run high octane but they are running two and four cylinder 650s

Also if you dont mind me asking, how do you get 73mpgs!

What high octane does is just prevents pre detonation due to high compression.

As for getting great milage, not sure you can get 73mpg with the Savage? where did you get that? If you want to increase your mileage then ride like a Grandma and tune that carb well.

Still running the stock jets. I'm just too lazy to contact Lancer about getting the proper size. It's not a Hayabusa so I don't ride it like one. I baby it. 73 is actually a little low. Some of that was when the temp was in the teens. Your gas mileage goes way down when it's cold outside. 73 is an average between summer and winter. I expect just summer mpg to improve even more.

It will. Stone stock my 98 averaged 75mpg, on west TN garbage gas (A&M Market in Bolton when it was still decent to stop at). Almost all 2 lane country roads between 35 and 50 miles per hour. Dodging cows and ostrich farm escapees... 90 miles a week commuting used 1.1 to 1.3 gallons. My 2003 uses more than that a day on its 72 mile round trip on TN-14, I-40 and US-51.

Oh, I have spare jets and I'm off Thursday, Saturday and Sunday this week. 6-10 pound catfish in the pond, bring minnows.
