I personally had a 1988 polaris indy 650. It was one of the most reliable sleds i have ever had. For being in the late 80's and early 90's, those sleds were the s#it, if you put pipes on the thing you won't believe the difference. I drove a 91 Indy 650 with a newly rebuilt motor, PSI pipes, and K&N filters and that thing wa one heck of a sled. Pros are that things power and reliability(if it is and was taken care of) Cons the suspension, older sleds are not mogul eaters, overall its a good sled though
My 650 has been good to me.. the best upgrade I have done was install an extra 10 suspension.. also the 12.8 gal gas tank makes life easier too.. I recently took my slp triple pipes and went back to the stocker.. this almost doubled my fuel milage... I should get over 2000 miles this season w/ no major problems. The motor was fresh at the start of the season..
I bought a 89 650 new. When I sold it it had 10,000 miles on it and still looked like new. I ran it stock for a couple of years then I had it ported, heads cut, carbs bored, SLP pipes, Fox Shocks, and seat and tank off a newer Indy 440 bigger tank. The sled was a blast to drive. The motor work really woke that thing up. If you add pipes get your crank welded. Riley
I`ve got a 91 Indy 650 with about 15000 miles on her, and i dont have too many complaints, the things that have happened i can understand because the guy before me didnt really take care of it and the mileage. Its a great sled and I hope it lasts me a little while longer.
Oh, I forgot to add it has no problem keeping up with my in-laws formula delux 700.
650Indy those 10,000 miles were on the origional motor. I did brake the crank at about 6000 miles and did bore it over .010 at the same time. I blew a head gasket just before I sold it. For the most part it was a very good sled. Most of it has to do with th owner. I am doing a crank job for a guy right now on a 92 650 and either his kid ran it out of oil or the oil pump quit. The inside of the motor is dry as a bone. Riley
I geuss it definatly helps having owned the sled from new.. I put two motors in this season alone.. went .020 over and three new pistons at the start of the season.. about 600 miles later sezied solid.. took the cylinders off, connecting rod went through the piston.. I had a spare motor.. slapped three new pistons in it.. good to go.. That's probably the best part about them any snowmobile graveyard has an abundnace of 650s and parts..
