My friend is just entering the sport with a used 670 Summit X that he bought at auction. Preseason checks were all good, compression 150+ per side, no other issues reported. The only problem with the sled is a chunk is missing on the outer 1/3 inch of the left ski. We'll cut the outer edges from the other ski for now for symmetry's sake and trim the bad side. He doesn't want to dump a bunch of money while he is learning to ride (Understandably so), so things like pipes/cans and other mods are off the table for now.
I myself am a polaris owner, so I know next to nothing about these particular sleds. I do know they were highly popular when introduced, and from reading other posts that 670 Rotax HO is a great engine. I had suggested Redline Synthetic VES oil (we don't know what the previous owner used), and for fuel I run Chevron 91 Oct. with a stabilzer, and am suggesting the same for him (That is based on advice from the tech at Carl's).
I would love some suggestions on oil, what to look for, quirks in the class, handling characteristics, or any other advice you may have for this sled that I can pass on. Last season was his first on my wife's sled, a '99 600 RMK, and he decided he needed his own. Any help you can give me is great.
