That should be a Mach 1 670. Mach Z was a triple. 670 is an awesome motor. If the body is in good shape, why not. On groomed trails , that will fly.

 

Far too many variables to know for sure. As mentioned above, is it a Mach 1 that would be a PRS chassis or is it a Mach Z with the triple swapped out for a 670 - which is very possible.

We are talking an almost 30 years old sled, it could be a good one or it could be nothing but a headache. Best case scenario, if everything you have been told is true, it could be a good sled for that budget - $800 is very low for todays used snowmobile market. Just realize what you are getting into, a very old sled. Be realistic as far as your expectations of reliability, and be ready to work on it.

If no electric start, it will be very hard to pull over unless someone upgraded the recoil. Expect it also to be hard on gas. Pictures would help.

 

Like already posted, this could be either a 1994 Mach 1 or a 1994 Mach Z that had the original triple replaced with a 670. However, "clutch upgraded" and "carbs replaced" has me hesitant...My impression is that the owner does not really know what he is talking about. There is no "upgrade" for the OEM TRA clutch, but there are cheaper replacement options once the TRA grenades. Also, unless we are talking about a heavily modified racing engine, nobody really "replaces" carbs. They can be cleaned, repaired and restored, but replacing the entire carburetor is definitely not the norm.

 

This is a double post. Posted also in Ontario section. It has been noted there that some of the description items are "off". OP posted the Facebook ad and description should in Arabic. Someone off here.

 

Here are a few pics from the FB ad. I'm thinking Mach 1 with creative decal work. The tank and console don't look right to me. Has the twin shutoff valves like the M1. You smart guys can dissect this better than I.

 

Did somebody assemble that…collection of parts…just to mess with the minds of the vintage nuts…?

Skis, console and snow flap are obviously way off, donated from more recent models. After that it get’s more interesting.

Is that a purple belly pan painted black…? Or the opposite…?

And a 670 with a black head suggests a very early 670. But…correct me if I’m wrong, but those don’t bolt straight into the F-chassis…? Could be re-sprayed, but still weird…

The sway bar linkage and the rear bumper suggests it’s for sure not a 1994, but more like a 1997…But those don’t have that brake…And the poor fitting handle bar pad suggests it’s the earlier 1993-1995 handlebar…

It has no front bumper caps, but if the rear bumper caps are good, it’s still a bargain at $800 because those are also on the list of unobtainable parts…

 

I think it might be a summit chassis that has been screwed over with parts from 3 other sleds. I would steer clear. Almost think that's a mxz tank and surrounding plastic, it's smaller than normal

 

The OP mentioned wanting a “reliable” sled. Just stay far far away from this mess.

Granted 800 bucks Canadian does not get you much these days. The guy is not overpricing it if it runs ok, but certainly not something a newbie should buy with expectations of a good reliable sled.

Alatalo, don’t think the early 670 ( if thats even what it is) would be a problem to go in the F chassis, its going the other way that sometimes won’t work.

I’m not even to rack my brain to figure a guess of what this is!
