Cool 95 Ski-doo 670 Rotax-good Or Bad?

I'm looking at a 95 Mach1 670 Rotax. It won't be used heavily, just for some local trail-riding and such. Sled seems to be in good condition, owner was pretty particular. my question is this: the sled has 7700 miles on it---will this still be good for a few years, or is this many miles gonna cause me some trouble?
Also, are there any common problems with this sled?
thanks

As long as the previous owner kept up on his maintainace you should be OK. The 96 Summit I'm putting together had 6600 miles and 130 psi in each cylinder. The 670 is a good tough motor.

670's are one of the most reliable engines Doo put out.

Should be good.
It is the first year of using 44 mm carbs and twin pipes on a 670 (except the '92 Mach 1 X) so I think it needed tweaking but should be good. Check with the 96 mach 1 specs along with yours to see if any updates.
