To my understanding - you can have your stator rebuild - much cheaper than to buy it brand new. WL

Jets exhaust, if it has pipes or not?

Prob. Stock. Does it have a single pipe or dual pipes? Jets have a number on them with size, clutch weights also have numbers on them

In order to check the jets, you'll need to pull the carbs and read the numbers that are stamped on them. Weights have numbers stamped as well, but the springs are color-coded.

For '98, the 700 came stock with Dark Blue spring, 60g weights, Silver/Blue in the secondary, 158 mains, and a 42 pilot.

Jetting and clutching will also be elevation specific. A setup that work at 1000 feet isn't the same as for 5000 feet. Jets are also temperature-specific, you need more fuel delivered when it's colder. Aren't sleds fun

Very true... That's why I mentioned stock pieces based on elevation up to 3000' (didn't mention that part in previous post).

It has two pipes... I guess I need to find out exactly what I have.. buddy called and said the clutch was full of dirt not a broken spring, but that its cleaned and ready to go.

Also, its slobbering alot at a idle, it will leave a black spot bout 4 inches across just oily type stuff. Is this due to too much oil in the fuel mix or part to blame on it sitting for4 years

most two-stroke engines of that vintage will leave a black spot when idling, especially when cold. It's the nature of the beast...

Ok... So maiden voyage was a bust. I can peg it and it will hit 6-7000 rpms rough , spitting and sputtering and backfires through intake and the exhaust. Not really a backfire more of a loud pop.,won't move, track will just inch foreward and after holding it long enough it will slowly take off, went out in the powder, runs like piss at anything less than WOT BUT once it goes it runs great, but if I stop I have to get off/ pedal and coax it into going again.... Any thoughts ?

Man... all I can say is I think It's a fuel & air delivery prob ,or it's a timing issue Sounds like a back track in the whole sled is needed & to start from scratch to se what you have & where it's set at ? Just my stuipid eskimo opinion (MQ) .

meburdick

Does it act like that on a stand, or just with weight on the track? Have you checked the track tension? Secondary clutch? Driveshaft bearings? Chain tension? Brakes pads (make sure they aren't hanging)? Double-check to be sure the parking brake is off?

Sounds like it's running on water...& it ain't no jet ski

Ok... sorry ,but 4 years sitting tank & everything else ,that has a coil that destributs into two for each cylinder does it not? Missing ? Hummm could be bad?

littleredstroke

After it warms up the popping goes away, like I say it runs absolutely perfect at high rpms WOT. Wouldnt a timing issue be all the time? The carb was taken apart, reassembled and cleaned by a guy who lives and breathes this vintage, he checked it over and said everything was good , do not get me wrong guys I'm just giving info I know.. I'm not trying to be argumentative because you guys obviously know alot about this and I know nothing.
Opened the hood and the cover over the belt, when I hit the throttle you can see the belt get tight ( like the clutch engaged) but then nothing. With the back end picked up it does the same but seems to pick up speed a little quicker.

Another example. On the hard pack at the parking lot standing on it, it won't creep at all... If I stand next to it and pin the throttle, and kinda push it it starts to move and after walking next to it for 20-30 feet it gets going fast enough to get on, once on it either bogs down or it takes off . Hope this is helping.

And once I get back to town I think I am just going to pull it apart and go through it ( with a bunch of help from you guys as I won't know what I'm looking at. Also, there is fuel dripping from were the exhaust starts , and at every connection .

I'm kinda trying to visulize your brob.as you have discribed . Loading up on fuel ,& thing does not go any where ,or has trouble doing so may be in the clutching ,I'm saying it may be all correct,but it my be sticking in the bottem end? You know what you have to do , is do a vidio of this & your headache may go all away,cause the rest of us can figure it out alot fasterfor you . Just my 25c

meburdick

I don't believe you've answered this as of yet... Also, what RPM does your clutch engage at? Did you verify the offset and deflection (I can't remember if you answered that one)?

Not a clutching issue here.
There is either too much fuel [not likely and ruled out with clean carbs].
That leaves either low compression or weak spark.

Low compression, could that be a head / valve issue? Or more like piston .

This is my plan.
#1 video the motor running like piss so you guys can see along with the slowly creeping issue.
# 2 photograph the engine/ exhaust so you guys can see the whole thing.
#3 I am going to pull the head, and take pics of pistons and head

With my experience with diesels especially, low compression makes it difficult to start in the cold... This starts on 3-4 pulls every time. Would the same not apply?
