Now that all I can buy here( upstate New York, year round) is gas w/10% Ethanol, Ive seen my gas mileage drop from 42+ mpg to about 38 and am not happy about it. Driving style is the same and the bike is always kept in good tune. It's a "93 Aspencade 1500, with under 40K miles and mostly always highway. I'm looking for ideas to improve the gas mileage, at least to what I used to get. I'm going to switch from dino oil to Royal Purple synthetic, and change to synthetic gear oil in the rear. I already run the tires at very close to maximum air pressure. Does anyone have any other ideas?

Always ride down hill? Draft semi trucks about 2 foot away from their rear bumper. Put a vacumn gage on it and drive to keep the needle in the high vac. range.

Life is a collection of stories we old people tell and hope a few will listen and carry them into the future.

There is a story to everything we have, everyone we have met and everything we have done or we will do or dream about doing.

We sometimes ride to forget, but hopefully we never forget to ride.

Was your mileage drop after an oil change? I see a few 1500s that are overfilled... It doesn't take much on the 1500 to leave the crank slapping (and wasting energy) in the oil bath.

If you suspect overfill, you can suck out a pint or so and have a look at the warm (not hot) fill level - set that to the bottom mark on the dipstick and run a mileage test to see if your MPG improves. Since the rear case isn't drained with the plug on the front case... and that rear case is evacuated by a scavenging pump, it's easy enough to be a bit over on the fill.

Also, are you running any electrics or other loads that may be 'seasonal'... I know my warm-up time is apprecibly longer on a 15* morning when compared to the 60* morning ride.

Don't warm-up for any length of time. Start and take off slowly.

Once warm, get to a higher gear sooner if on flat roadway.

Without heavy traffic and safe, drive 5MPH slower.

In your area, you know the traffic light sequences and where the stop signs are. Pull in the clutch and coast to stop.

If it's a major intersection and you just caught a yellow, stop, turn off the engine, put down the kick stand, and wait for over a minute.

It's unbelievable how much fuel could be saved in vehicles by just letting off the gas pedal and coast to the stop. You have enough forward motion to continue at a reasonable speed.

If you're not a liberal when you're 25, you have no heart. If you're not a conservative by the time you're 35, you have no brain.

Those who would give up essential liberty to purchase a little temporary safety deserve neither liberty nor safety. BF

Proper prior planning prevents piss poor performance.

If criticism had any merit, the skunk would have been extinct years ago.

Do what the Harley riders do and trailer the bike!


Seriously though, that drop in MPG is about right for using our taxpayers funded ethanol gas, pay more in taxes, pay more in higher food bills, and pay more for the gasohol, all for lower mpg. Welcome to our governments new version of economics.


Most common quote from a cager after killing a motorcyclist is?

"I never saw him".
