Title: Will engine braking activate fuel cut off?
Post by: cyrusyn on December 22, 2008, 09:57:15 PM
I'm wondering if a 2000 GS500E can do a fuel cut off while engine braking.
I am guessing that it won't since it has no ECU but just to make sure...

So in order to get 150 or more mpg, I should squeeze clutch more often on downhill...

ummm, in order to get 150 or more mpg, you need to have a scooter, the GS just wont get 100mpg while maintaining SAFE speeds on the road with the gearing mods you'd need to do.

The GS already gets really good mileage, even for a bike. Just ride it and have fun. If you find yourself unable to afford gas for the GS, go get a bicycle or ride the bus.

The best I've ever seen was 85 mpg (by qwertydude): http://gstwins.com/gsboard/index.php?topic=42966.0

This required an 18 tooth front sprocket and driving at low rpms.

Here is another similar thread: http://gstwins.com/gsboard/index.php?topic=41297.0

Many "hypermiling" techniques I would consider dangerous or downright inconsiderate of your fellow motorists. please don't attempt to get 150 mpg out of a gs500.

Yes, dangerous and inconsiderate in a car, suicidal on a bike. Besides, there is nothing you could ever possibly do to a GS that would let you get 3 times average fuel economy.

150 mpg... Yeah, Im expecting too much out of this small twin bangers...
I meant 150 miles out of the 5 gallon. Right now I am only getting 140 miles...

Oh!  150 miles to the tank!  That's what i was getting until I got the carbs straightened out.  I had a vacuum leak and a clogged pilot jet.

You shouldnt see anything shy of 200 miles per tank from a GS500 in good tune, they generally get insane fuel mileage as it is, like the kind that is only matched by the ninja 250.

I was getting 240 on 4 gallons (to reserve) on rides from here to Key West (140 miles one way). That is with my wife and I on it and with the saddle bags stuffed. Now with E10 we get 220, thanks Governer Crist.
