I had a '97 Mach 1 700 and LOVED it. A freind has the '97 Grand Touring and other than replacing the shock once no problems and he uses it LOTS! How much milage on the one you are looking at? Does it have air ride on the rear? There really wasn't much went wrong with those units. I Beleive in '98 they were rated top of the class. Go the Ski-Doo website and under sleds you can scroll back a few years and you'll see a new one there.
Check and see if the recall work has been done to it. I
think it was the voltage regulator, hair line cracks on the
clutch sheave and oil pump adjustment. I had some issues
with my 98 700 triple motor but others have not so it kind
of depends on how it was taken care of and if it was
properly summerized. The PTO crank bearing was a problem on
some of these motors.
I think you have a great sled. I'm running a 98 formula 111 with exactly the same engine. I've got 4000 miles on it. The only problems I've had are with the stator and CDI box. As far as bearings on the crank just about everyone and their dog says the bottom end is going to explode due to bad bearings but I have yet to meet anyone who has had that experience. One fellow I know has 12,000 miles on his sled which is the same as yours. Always let it warm up before riding and add premix oil to the gas when it gets really cold out.
