Been a ski doo guy forever. Saying that this sled is one I would never buy. And the 600 triple. Both have the same problems. I always go for the 670. Have have 4 now. Not only are they wayyyy more reliable but faster as well. The only triple Mach I would even consider is the 800. Those are fast. But still a triple. Really hard to be the twins. Still love the look of these sleds. Even tho they don’t handle for sheot. Best of luck with er!!!

Yeah, the 670 mach is a great sled. This engine will last me a long time since I'm not going to be putting a lot of miles on, maybe some classic lake cross racing but mostly light trail riding. I think the 800s have better oiling provisions, i'm going to look into that. But yes the last year's mach z's are the ones worth getting, but cost more $$$. They sound cool, but it's a heavy sled.

This was a late night lmao to many beers

I had to take out the part where I sync carbs because that was too much to handle lol

Who do you plan on sending the crank to? It needs all 3 rod sets and all main bearings. Have the cylinders replated too, the damaged one at the very least. Good luck with it!

I know a guy in Green Bay who did it, $1000. Then I bought 3 freshly re plates cylinders from millinium tech, and new spi pistons, rings, and gaskets.

@@Trikekid84 $1k for a properly done triple crank with all new parts is reasonable. So long as it's assembled right and is air-tight it will run well for a long time. When I do multi-cylinder crankshafts I prefer to have the crankcases it will be going into on hand. I can set the widths perfectly and once it's trued can be set in them to avoid getting banged around.

@@BillyWillicker yes, I gave the guy both case half's and he does cranks for many different sleds. Stuff that I own, friends, and racers from eagle River and other things. I would not know where else to bring the crank, and I definitely don't know how. I understand how to rebuild a single cyl crank, but never done one 100% by myself yet.

@@Trikekid84 It's just like a single, only a lot more width setting, and a LOT more truing. I do mostly singles and can get them down under .001" runout and usually better - not sure why I do when the spec is .003", but hey better is better. The straighter it is off the press the easier it will line up in the end so the press work is important. Cranks are definitely one of those things that the more you do the better you get.

Looks like that engine has been apart and reassembled before, otherwise where did the ball bearings go? That 97 crank and crank case are a one off, if you plan a rebuild you will be good, if you get a used crank it will have to be 97 to fit your case, the 98 99 and 00 are all about a half inch wider

That's actually how the bearings are made, besides being broken. I'm using the case halfs I have because they are still good. 👍
