Question about reeds..
Hey everyone! New to site and just got another snow machine after a 15 year hiatus. Used to own a 89 Bravo and a 94 V-max for getting around Bush Alaska (Aniak). I just got a pristine 99 600 RMK. Runs awesome and starts first pull every time! Problem is that after 10 minutes of idling and about an 8 mile round trip in 4 foot of slush snow it used over 1/4 tank of fuel. I run easy and pull a lightly loaded sled for hunting supplies. Although the top end was just re done and everything is immaculate, I figured the reeds probably have never been changed. Asked previous owner and he never did it. So... Pulling them out this weekend and changing to Boyesen Power Reeds as I figure while I'm checking them, may as well replace.. (It's a Bush Pilot thing.. Lol) Question is... Will new reeds help the fuel mileage out if at all? Again, I ride easy and just use full throttle usually only for crossing water when surprised by it and when needed for boggin' thru a bad section to get to a stand. Like to get as much fuel economy as possible as some predator hunting trips take several days and many many miles in Idaho high country. Thanks in advance for any help!!

I put the same reeds in my Storm. They did not help my fuel mileage. It sounds like you may have another issue. Have you checked for fuel leaking? Have you checked your plugs?

sounds like a lot of fuel

how do the plugs look?

whats jetting?

should be flat top carbs which are very easy to work on

Thanks for the replies.. No leaks and had just changed plugs before that fuel guzzling run. I figured I'd start checking thru everything Sunday again when I check/change the reeds.. I thought it was an exorbitant amount of fuel to use as well but wasn't sure how sleds newer than the ones I had in the mid 90's did on fuel. Thanks again and I'll post what I find..

And one other thing.. This sled will start, first pull, everytime without using the choke. Doesn't matter if it's 50 above or 20 below ambient temp. I almost hate to mess with it but I assume that would mean it's a bit rich at least on the low end?

New reeds probably won't do much unless the old ones were noticeably cracked and chipped.

How did you determine gas mileage? Just by the gauge? The only accurate way is to start full and then fill up at the gas station when you're done.

It's not uncommon for my group to get in the low 5 mpg range in deep heavy snow. In fact Baller would be overjoyed to get that many mpg, ever! Even with our new expensive sleds, it's rare to get over 8 mpg, and I have seen below 7 many times on my RMK.

You should get double digit mpg if you're riding on a packed trail, but in deep snow, you can burn enough gas with a sled to consume the Saudis' surplus production and raise crude oil prices on the world market.

Lol.. Thanks Rubi. I changed reeds and we are getting much much snow outside today and tomorrow so I'll take it out and see how she does now. In reading up on this RMK, I've noticed a lot of riders seem to blame the ACCS for bad fuel mileage. I'll see what happens this week and hope that it's a bit better.. I did use the gauge for determination but also filled it up upon returning to the truck and it took a bit over 2 gallons to top it off. Thanks again for the info. You all are great!

Almost deleted this one... not spam lol.

I would imagine average fuel consumption on that sled should get you around 120-150 miles on a tank if you aren't breaking trail.

Even my grandpa couldn't get 150 miles to a tank, and he passed away in the eighties. I haven't gotten over 100 miles on a tank since the first week I had my sled! (Well, I probably didn't even get 100 miles total my first week because I was stuck in the prickly ash the whole time.)

I think my XLT used to be up around 125 miles and still have some left in the tank. My numbers could be very optimistic, I haven't done any hardcore diamond pounding in 8 years.

Rubi 12-23-2014 02:43 PM

I didn't realize we were talking about diamond pounding. I guess I've never really pounded diamonds enough to know about gas consumption. We put on almost 90 miles with Riley one time, but we stopped for gas during the day. When Baller rode down to Alex from Fargo, we put on 100 miles, but I broke all the motor mounts on my sled so gas mileage was the least of my worries.

Dirty_Harry 12-23-2014 03:14 PM

My Uncle's 600 twins would do the same if not slightly better than my XLT (or dad's). All we did was diamond pound back in the day.

Thanks everyone!! This is why I joined this site and only this site... Precise and informative answers. I got the reeds changed, fixed the leaks, and she is running great. We are getting quite the white Christmas and I rode it over to friends through town for supper. Now that we have some snow, I'm going to take her up stump peak area this weeknd and see how the mileage does. Can't help but be better! Also got the ACCS all routed correctly and it still starts first pull and accelerates here at 5500 foot MSL so I figure it's all good.. I have a ski pressure question but will start another thread for that! Thanks again everyone and hope you all have a Merry (and very white) Christmas!!

Just an update.. Ran the crap out of the RMK yesterday. Around town and up the hwy for a bit and used less than 1/4 of a tank. I think it's all better now and I can live with that type of fuel economy as I ran it harder than I ever do when in the back country alone. As this is the "newest" model snow machine I have owned, I'm surprised at how fast that thing will scoot. I thought my 96 600 V-Max was fast back in the day but I really think this RMK would smoke it. At least it seems that way. Thanks again for all the help you all!! I really appreciate all of you who took the time to post the help! Have a safe holiday season and I hope you get as much snow as we've gotten!!
