I have an 02 ZR 600 efi, it's got 6000 miles on it, but only 200 on a fresh top end. I'm a big guy, about 300 lbs, and I'm not getting very good mileage with it. I can get maybe 75 miles to a tank if I run it bone dry (prem. or reg. fuel) and about 60 before it hits E on the guage (the gas gauges on Cats are dummy guages). This is while doing about 60 mph most of the time. The thing is, I want to go faster than 60 mph, I like cruising the ditches at about 70-75 sometimes, and I don't accelerate slowly. I talked to a few guys, they said the gas mileage should still get progressisvely better after the rebuild. Does the type of oil I use have anything to do with it? I'm using Esso synthetic snowmobile oil this year, I know it's not the best, but I'm on a budget. The guy who rebuilt my sled said if I clutch it to my weight I should get better mileage too. He said I should put a two stage helix and different springs/weights in it and try to gain about 2-300 RPM. I've seen these fuel reducers form Bikeman Performance, they look like they could work. Anyone used one of these? What can I do to get better mileage, or do I just have to get a bigger sled, which I want to do anyway?
