97 Polaris Ultra 680 Problems?

Hey, I just picked up a 97 polaris ultra 680 and all I've heard from people is that those sleds were fast but had lots of problems, particularly with the engines and cooling. I was wondering if this was true and if someone could give me some advice to prevent these problems from happening. Any comments or advice greatly appreciated!

Preventive maintenance!

Get the manual (look for the manual downloads post here in the forums), and do what it says. You will find there is pretty much a seperate section for the 680 Ultra, and there are a lot of things a little bit different about it. If you maintain it like the book, it will last longer.

I have 1997 Polaris Ultra Touring and was told the opposite. I spoke to a Polaris mechanic (respected mechanic in a small town) and he mentioned this case reed tripple is bullet proof. A buddy of mine is a walking Polaris encyclopedia and he said the same thing.

Your sources may have been thinking about the Polaris XLT engine which was prone to failure in the early years.

No, I have had many experiences with the 580/597 triples, and never had an issue with them.

I only know to 2 guys that I ride with that have 680 Ultras, and they loved them (one a 96 RMK, the other a 97 SP). One of them was constantly working on his (RMK), though he did mod it a bit. The other guy rode his (Ultra SP) for a year and sold it because of all the small things that went wrong with it (including some chaincase issues). The RMK Ultra eventually blew up the chaincase, which in turn destroyed the engine (not sure how that happened myself), so my cousin stuck my old Indy lite 340 engine in it (lol) and rode it for a season.

These guys also ride pretty hard (our trails are defined a bit different than the lower 48 does) including hill climbing, tree riding and jumping (not that insane crap though). So for cruising and the occasional opening of it up, they probably do better.

My 700 blew up 3 times and was still on the trail more weekends than the 2 Ultras that I have experience with.

most of the issues that popped up were do to differences in design compared to the rest of the polaris line-up. So I go back to my statement, read the book and do what it says, it will last longer. Use the lubes, torques, retightening schedules specified ect. There is no doubt in my mind that these are good engines and such, it is just people don't realise they are different! (look in the manual, you will see)

The 580's were bullet proof, put just under 10,000 miles on 2 1993 models before they were sold. Both are still running good with no rebuilds!

Are you talking about the 600 triples being the problem engine?

The only negative comments on the Ultra's engine were regarding the 1996 MY. It had problems with the oil reservoir for the gear driven coolant pump. This separate reservoir was elliminated in 1997 MY and received its lube from the fuel/air/oil mixture. Also some had kinked oil and coolant lines. All fixed for 1997.

Early XLT engines I think had issues with piston skirts breaking off. Resolved in later model years.
