nitroking72, I agree with you 100%. I wish he would just take all this stuff and bring it to the scorpion reunion and sell it there. But then again that wont happen he dont know what hes got so im sure he would never do that, and its too bad because there might be somethings that some of us may really need for our old scorps. You know rear idler wheels, Bubble nose hinges things that it would be nice if there was some more of them out there.

I have always seen the numbers but never put much thought into it. Thanks for the info tom. Did the mark series have any special meaning to there numbers too? jonct did you ever but that stinger let us know what happens with that.

stingerater so what you are saying is for instance I have seen s032-xxxx for serial# so that would stand for s=stinger, 0=1970, 3=300 engine, and of course they are all 2=mark II chassis? So a stinger with a 493 would be s052-xxxx, a 634 hirth would be s062-xxxx, and a 793 hirth would be s082-xxxx? I knew the s stood for stinger in these serial numbers, but never new the other numbers stood for anything.

I just noticed something on that mark Iv hood the bump on the hood is on the clutch side of the hood. Its on the flywheel side on the stingers. I never noticed that before.

You know what pararailer is right. If it needs no work and you can jump on it and ride it. Go get it its only money, but try offering him less at first and see what happens. If you are cheap like me and buy one that needs work for $500 next thing you know you got $2000 in it, and just should have brought a proven runner in the first place lol. Yes its easy to do.

Go to vs then go to the classifieds type in scorpion in the search, and it should be halfway down the first place. If that guy has a mark Iv and you can get ahold of it jump on that one even if its all apart. If you not intersted let us know there's a long list of us who would love to get ahold of that. or I could just go buy dans hey its only money cant take it to our graves lol.

Yep my thoughts exactly ddub. If I had one that's probably how much it would take to get it from me too, but im like you. I will buy it cheap, and it ends up costing more than i could imagine in the end. Oh well its a addiction thats for sure. Yea my back hurts just thinking about moving one of those.

My guess that was around 1970 by looking at the sleds?

Ok good to know ddub. All i know is if you see a mark iv from a distance you know what it is. Anyone seen the one for sale on vintage sleds right now? To bad you didn't follow up more on that mark Iv more I hate the thought it may have ended up in a scrap pile. Hope i can end up with one someday, but i have my doubts but you never now.

Not many mark Iv around, my guess is if its black with the red stripe its a mark III or mark I or II. If it says mark IV take a pics for us that would be interesting to see the ones i have seen they were red metal flake like the stinger.

well the thing is with that stinger is the sa370 is not a valuable motor. Now its a good motor got nothing against them, but if the sled had a 340ss 293ss those are worth alot more. Last year I seen one here in mn with the 340ss in great shape for $1500, not sure if it sold or not. I seen one here this fall on cl for $750. looked to be in good shape. The add said it had a 300 sachs? so not sure if its was a 293ss or stadard 293. Not on there anymore so not sure if it sold or not too. The sled you are looking at is in really good shape by the pics i seen of it, But like i said how is the gas tank? what shape is the tunnel in under the seat and over the track, how is the track? what shape are the drivers in? is the seat getting ready to crack in anyplace? In my opinion $500-1000 and $1000 very tops. Just remember with this 70 stinger you can still get new hoods, and seat covers from scorpion jack so its not like this is the only one out there in this good of shape, however it should be able to win a unrestored class in a vintage snowmobile show. Hopefully a few others chime in on this and give you there opinion on it too. For $2000 i don't think its going anywhere any time soon.

jon, To my knowledge all 70 stingers have the angled exhaust hole on the side by the chaincase. What you got there is the sachs cassis the exhaust that exits on the right. If the chassis was for a hirth it would exit to the front of the chassis, and had the hood with the bump on the right side to clear the larger hirth engines. The angled exhaust port i believe was for the 793 hirth. that had tripple pipes one used that exhaust hole. the other two exited on the right side where the donaldson is.
As for the serial number s042 To my knowledge its just the serial number and is the number to that sled. As far as i know Scorpion dident document a serial number to a certain engines like some other manufacturers. As for the engines I have seen literature that says the stingers came with the Hirth twins 399, 339, 493, 634, 793, and with the 293ss and 340ss sachs, however i have seen these with the standard 293 sachs the 370 sachs, and i seen one with the kohler 440 in it. And they sold a kit for the 370 sachs that was called a git kit. It came with a cast iron cylinder, and head. that was a (396cc) 400 and had a sachs tuned pipe, and a gem intake. and they where loud as hell. I think you could order what motor you wanted for the singer.
So in my opinion you got a unmolested sachs stinger there. if your concerned about anything check inside the gas tank and check it for rust. you can unscrew the cap on the top in front of the motor where the fuel line enters the tank, and look in there to see the condition of the tank. This can be a problem with these if they sat for a long time without good gas in them. (if you don't mind me asking, is it the one i seen on ebay recently?) Im not interested but i think they where asking way to much for it. I thought it has the 370 sachs too.

I agree with giving the duster a try. I got one on my 400 whip. Mine has 6 pucks and a black spring. I cant remember what rpms it engages at but its a little higher I like it there. Lots of sleds 6 pucks and the orange spring works great. cant get any more simple than a duster. As for your clutches what you are reading sounds right. Except i thought the treads are a English thread. the bolt and shaft works good but sometime they are seized on. so take your time don't strip out the threads on you clutch or shaft or you will have a bigger problem. There are clutch pullers available on eBay for the power thrust if you cant get it off with the puller method you are reading about. Yea I don't think hitting it with a hammer would be the best thing too.

Ok guys problem solved. Now im a little puzzled. The 94c duster I tried on the hirth was a pile. The pucks really did not go in it all the way in the slots on it. Right clutch right pucks. Anyway I could not remember before where my old scorpion clutches went. I found them in a box today above my shop. Two power thrust I One power thrust II and a 1970 clutch, and a 1190 Salisbury. All where 30mm like I thought they where. I put the power thrust II on like Obj1 said I should try when I talked to him at willow river this year, and I like what I see so far. Have not drove it yet! no snow (WTF). anyway the reason I started this thread was in regards to the power thrust I clutch have that looked like it was new, and I thought it came off my 75 whip before I put the 94c on it. The reason I took it off was it was sticking and I took it off to try a different spring than I normally used on the 94c. I liked it so i left it on there. Now I had a box of 94c clutch stuff then. I am in possession of a power thrust I for a 25mm crank. I have never payed much attention to this before, but I thought cuyunas where a 30mm crank. I did not pull my 75 clutch off to check today, but I went to the local snowmobile bone yard and looked at a few cuyunas and twin jlo/rockwells today thay all had a 30mm crank. So was there a cuyuna with a 25mm crank? would like to figure this one out. Maybe I got this clutch mixed up, but I doubt it. Need A little education with this one.
