threw a new primary clutch on and it helped a little nothing like filling up at every gas station you see and the doo guy was ripping me to. That ended when the doo 7triple blew up and he had to ride the cat back to the truck.
Someone earlier mentioned they bought a Z570. Well, I put 800 miles on one this year and actually got between 18-20 mpg. It was fun on a long run and watching my LC buddies running outta gas
. Gotta say this sled can hold its own on the trails too. Oh yah my top speed I clocked was 91 mph and this is the ABSOLUTE fastest I could get it to go all season. Still not too shabby for a learning machine.
I ran a lot of Cats over the years and none were too good on mileage. Something you guys have to remember. If you're running clutch kits, these can hurt mileage. A lot of the kits end up throwing more weight at them. This will make your motor pull a lot harder on some machines and your mileage will suffer. I had 3 800 ZRT's and they all lost some mileage after I got them clutched to run right. Over the course of a winter it doesn't amount to that much money though. You just have to eat a little less or drink a few less beers on the trip. Now I'm running a '01 800 MXZ with an RK Tech head and getting 14 - 15 mpg. The head helped a bunch. Went from 500 mains down to 430's.
You guys with the 500`s that are getting the low numbers should call D.D. or 1-800-431-cats in canada,because you will go from 8-10 to 13 plus and add power at the same time .My 711cc gets 13-15 mpg and will smoke the 700 /800 yellow and blue boys doing it !!!The other one has asuper single pipe ,d.d./dlyton cluthing ,lite weight camplast track ,d.d. power breather v-force reeds,whal brothers disc and gear.By the way this 500 inside is stock and will beat the new crop of 600~s also an added bonus is knocking off the vipers at all speeds.This sled engages at 5000 rpm the 711 5500 rpm.The 500 gets 13-15 all the time now at 8300-8400. ...............My The Best Cat win.....................
Just bought a used 98 pantera 800 triple recently. I ran the tank dry in 90 miles. so I guess I got about 9 miles per US gallon on that trip ( some trail, some powder, some full throttle). Had hoped for better. Had heard 800's were pretty good on fuel. do you think that meant they used a lot???
Tweaked '97 ZRT 600 getting about 10mpg on average, best was 14mpg and worst was 7mpg(that was when testing the jetting though). Stock jetting would only get about 8-10mpg, but now depending on my thumb
I get from 10-12mpg running 340 mains w/pipes and silencer, reeds, etc.
