hello, I posted this on another thread, but not sure it anyone saw it or not..My story is I purchased a used 96 vmax 600 w/ around 3000 miles on it...sled looks min conditon... I put a total of 50 miles on it, and it seems to run fine. Just the other day I found out that the previous owner let it sit for two years in a barn without running it...I guess this season, he changed the gas, and it started right up.
what kind of problems will this cause? I keep hearing of piston burn out due to dirty carbs, but wouldnt I have noticed this by now? if carbs were varnished or dirty, I would assume that after 50 miles, I would have noticed problems..I ask this, cause I cant clean my own carbs, and dealer gets around $150.00 to do this, and I hate to shell that out, if nothing wrong...anything else to look for? thanks much, Pete
 
There is a large nut on the bottom of the carbs that can be unscrewed and removed for checking if there is any crap stuck inside of them.You will still have to put a wrench on the secondary to remove it.If they are clean i would think they are good to go !But if there is any crap at all i would think you had better remove carbs and read up on how to clean properly or run them over to the dealor for cleaning.Cheaper if all ready removed.What happens is a small partical will come dislodged and stuck in the main jet causeing it to lean out and then the moter damage.
 
well the only damage would be dirty carbs(i would pull and clean ASAP)and
maybe some rusting on the crank if the sled was not fogged before storage.

pull and clean them carbs,then wright down what jetting you have..
 
great thanks..

i will have to make apt w/dealer..I dont know the first thing on carb cleaning.. and even reading the techs on this site, Im still confused, and would end up doing more harm then good......I had sled running for around 50 miles yesterday, and had it really opened up alot, and ran perfect..I figured if anything was dirty, that its cleaned out now...I know tooo little about this stuff..thanks
 
have the dealer wright down your jetting then,,good thing to know what ya
got in there for future ref...
 
looking at bowl

can you explain how to remove this nut and look into the bowls? do I have to remove anything to get to this nut? where is this nut located? right under the carbs? and I take it, there is a nut on each carb? how would I see in the carbs by removing the nut, is the nut on the side of the carb, so that I can view in there?
 
The nut is a small 'bowl' from under the main jet. You can look in the bowl in the nut to see if you have a science project or not. If it's clean, you are 'likely' ok. You would probably have to take the airbox off to get at the nuts.

There are some pictures here: http://www.totallyamaha.com/snowmobiles/aaTECH/carbs/cleaning_carbs.htm for you to look at. They aren't exactly the same as yours but similar. carbimg8.jpg has a shot of the nut on the left carb(carbs are upside down in the pic). carbimg11.jpg has a shot of the inside of the bowl with the nut installed. The nut removes the center circular portion of the bowl.
 
the main jet nut is on the bottom of the bowl,you still need to remove the
carbs to do this.you wont be able to see your jet's with it in the sled.
 
im probably gonna run it, until this spring....Im having the dealer close the sled for me this spring, and they are draining the carbs for me, I will have them check it for me this spring...if i damage my motor in mean time, I will cry on this board, and be subjected to lots of "I told you so's'' LOL!!!!!!!! they have no apts for a couple of weeks, and I wont wait that long to ride, esp with all this fresh snow here in NY...like I said...It runs awsome..........
 
seafoam?

will running seafoam dislodge anything, and clog up the jets? or is it designed to disintigrate everything? im sorry, real dumb w/stuff like this....and can this stuff be purchased at auto stores? or online?
 
where in new york are you located? i may be able to help you out & get this sled in top shape to be riding with no worries?
 
yankeeslover, sleds always run "awesome" just before they melt down! dont be a statistic! do yourself a favor before you regret it.
 
Don't bother having the dealer clean the carbs in the spring, they will just be dirty again the next fall. Gas evaporates over the summer, that's what causes "dirty". Just clean it up really well, grease, and fog it in spring. Have them do a pre-season service on it in the fall before you ride. With that being said; it is very easy to be intimidated by cleaning carbs, clutches, etc., but if you take your time and try it, you'll probably be amazed at how easy it is to do. Just takes patience. And, I would be very nervous to run a sled that sat so long without cleaning the carbs.
 
I have to agree, i always had my dad clean the carbs for me, until this year when he made me do it, i too was a little shy, but i have to tell you it is REALLY EASY, just pay attention to what you do. The main thing you will need to do is

Remove the airbox (two bolts on the top near cowl)
remove coil from air box, two phillips screws.
Loosen the 2 clamps on the airbox to carbs.
This will let you pull the airbox off.
Then you can simply pull the nuts off the bottom of the bowl and inspect the gas that comes out or go the next step.

To remove the bowls you will loosen the caps on the Other side of the carbs (near the motor) pull the carbs out. You probably won't need to unhook any lines other then the gas lines that use a simply clamp on the bottom of the carbs. Carefully work them down and off the bottom of the carbs.

Then you will be able to tip the carbs up on their side. There are 4 or 6 screws on the bottom of the bowl this will let you pull the bowl off and see what you have. If everything is clean you may be find putting the bowls right back on and putting the carbs back on and be good to go. If they are dirty you will want to clean everything up real good and make sure the passages are good.

I realize is may seem like a tedious task but honestly the hardest part is getting the carbs back in the boots after they are all cleaned up.
 
Anybody that owns and rides a sled needs to know how to do this,,it's crazy paying a dealer to do somthing as easy as this.
 
Taking the top off the air box makes it much easier to put the boots on. You can use your fingers to slip it back on.
 
i always just did it half fast pull the bowels and look at them if all looked good put it back together till this year my g/f's sled i got it back to gether and started it and it was pretty much running on 1 cly had to choke it to keep running... so take it all apart again... and well i found that two of the three pilot jets where blocked solid... so cause i half fasted it i had to do it twice... no fun.. and for the work it actually was to do it right the first time... leson learned.....
 
maybe i will try it myself

so other then taking the airbox off, wich sounds like a few screws, then it lifts out, there are no other wires or anything to unhook, other then the gas line under the carbs? how do I close this off, to prevent gas from leaking out of the tank? and also, once I take the carbs off, do I have to hold them carfull? I dont have a garage, so will have to take off outside, and run to sink, or bathtub(hehe) but either way, is there anything that can fall out of the carbs if i hold the wrong way? and also, do I cover the engine with anything while carbs are out? I may have them out for a couple hours while I run back and forth to this website, back to the cleaning job....Is it really not this hard to do? I really am not that handy at all, and do not, want to put something together wrong, Im famous for taking stuff apart, and either putting back wrong, or forgetting which way it went..thanks, Pete
