I have a 91 that I put a 580 ZR triple port top end in and the larger ZR VM40 carbs. The top end is a direct bolt on to the 550 bottom end (shared bottom end). The carbs took some fabbing to get it to mate up with the air box. I also put the ZR clutching in it with a roller secondary clutch.I just got this sled running and am wondering what to replace or any tips, shouldn't skip oil injection or get a new CFI box. Let me know!
I have a 141 Proclimb skid I want to put into it. I’ve done a few in the past and I’ve actually sold 3-141” skids to guys back east already this year. However much my wife likes her older Cats, I’m trying to convince her into riding our ‘05 Summit 600. She’s not convinced so far.Reeb, those 580 Z's are sweet and rare. Love it
I think you can still upgrade the rear suspension with a 136 inch skid from a 99-04 Cat sled with 136 inch skid. The link I posted above, some folks did that.
