We have three 95 V-max 500's. They all run fine but, one of them is using twice as much gas. I have read about this many times but refuse to believe that its the nature of the beast. Has anyone been able to figure this one out? The gas guzzler is a little weak in the midrange. The plugs always look pretty good and it's not leaking gas. Were the heck is all that gas going!!!!
I would assume it's a carb problem but any help you guys could give me would be great!!!!!


Thanks, FishX
 
Check the reeds.

Edit: I just realized that I don't know if the 500 has reeds! Anybody?
Edit2: Just checked Ronnies, they do have them so check the reeds. ;):D

IT IS NOT JUST THE NATURE OF THE BEAST we run 3 of
these,,95 a 94 and a 96,,all are bone stock and in mint shape well maintained
and we get 11-12mpg..somtimes even a little better..

The key is maintaince...carbs, clutch, belts,ski alignment,
track deflection,etc, etc.....

Some peple just don't take the time to do it and bitch and complain and
say "junk sled"....Gezzzz.....

A good place would be carburation,,make shure it's at stock settings
and make shure you clean it well,, blow out with compressed air

Reeds?

We also get about 10 to 14 mpg on the other two sleds. We will definitely clean the heck out of the carbs. I've read about bad reeds before but how would a bad reed increase fuel consumption? Don't the carbs control the amount of fuel going to the engine? Do you guys think all this extra fuel is being burned by the motor? I guess it would'nt bother him if it was twice as fast!!!!!!!

Thanks Everyone, FishX

If the reeds are worn the motor won't be running at peak performance and use more fuel trying to get that performance back and run with the other sleds.

Better than 12 mpg? on a 94 600 vmax....whoa! that is so good, I have never heard of such great gas milage on those sleds, ( I used to have one), I got around 90 to the tank ,but that was after some slight modifications! you def . do not have a normal 600!

We have 3 unusual sleds then because that what they get,,I just know
how to tune,,I don't bull shit.....

We can get bettwen 100 and 110mile per tank or a little better on our '94.
our 95 and 96 a little better,,,got to remember we'er not throttle jockeys
our sleds are not the fastes,,but we don't care,,we tune for gas milage
and run alot of hard packed trails,,not much deep powder busting.

Come ride with us some time... ;)!

My 9-yr old daughter considers our '95 600 to be "hers". Sez it steers easier because of the shorter track.

She gets 100 miles per tank on trails, but doesn't really like trails. She gets 85 miles per tank off-trail. When I ride it, I'm lucky to get 75 miles per tank.

If the reeds are healthy (they usually are), the main jet size and needle clip position are the primary determinants of fuel economy. Stuck floats or other carb weirdness (even fuel restrictions) will dramatically reduce economy. Then comes clutching.

Then comes the all-important thumb-position. :l
 
hey yammy. under normal driving conditions my sled 1994-vmax600 will get over 110 to the tank approx. i went out the other day put on 90 fast miles and had a quarter tank left. guys im sure every body will agree carb sycronization is very important to proper fuel economy.i will be buying one of those tools from royal very soon .it will pay for itself fast.

Id have to see it to believe it!
 
i didnt believe it either but i was keeping special watch on the gas milage because its a new sled to me this year and i hate running out of gas in the bush .the fuel economy is very good, but like anything else you can get less if you hammer it or go goofing around off trail ,then its 90 max.hey might be even better now that i found out the coil is goofy and replaced it. lol! boy that led me on a wild goose chase for a day or too.
 
Still not fixed!!

Cleaned and checked carbs. Reeds looked fine. Comp. was 121psi. Did not sync the carbs( Could this be the problem?). I know the primary is fine but I need to take a closer look at the secondary (spring twist). Help!!!!!!!

Thanks, FishX
 
My 96 will get right around 11 or so and I have pipes and run it pretty hard. (Of course, I'm on 1 cylinder right now, but I think that's unrelated.)
 
I had a guy come to me two weeks ago with the same problem, I tore into it and found out it had a bad needle and seat, and the carbs weren't in sync.
 
my 95 600 was awful on gas earlier this season, and I mean awful, 5 mpg, 50-60 miles per tank. got into it and found that the needles were way too rich, now have them properly placed and am seeing anywhere between 10-14mpg with a usual average of about 12mpg. It has GYT twin pipes too. My mileage is now fairly consistent with the only variables being how hard I ride it and the temp. the colder the better mpg.
