Any one else think it should be honed out, because it has been rebulit and bored in previous years i cant notice that the rings are bad but the gaskets need replacing and i thoulght it would be a good idea on the rings to?
Ok i do agree with the honing part UNLESSSSSSSSSSSSSSSSSSSSSSSSSSSSS, you have a chrome or NikAsiL plated cylinder, then you do not touch that bore with anything PERIOD.
If you have the cast-iron bore, i would find the finest honing stones possible and run it through two or three time very quickly and call it good. All you are looking for is a light cross-hatch pattern on the cylinder wall.
It is my personal belief that rings in snowmobiles dont really have a choice as to wether they seat or not due to the fact that they are pinned in place. So unless your cylinder has some minor flaws in it there is no use to hone it. Once again this is my PERSONAL opinion.
Polaris is my way out - Other people just use a door.
My first controversy since I joined. Since this is important dont take anyones advice except mine. No, just kidding. Ask your dealer. Mine will do it for ten bucks a cylinder. I do all my own work except for a few things and honing is one of them.TriumphoverU, I have had my nikalsil cylinders lightly honed to provide cross hatching for ring seating on two occations. They did say however that they use a special stone for nikasil.
Hotrod-Or a cat- yes my first sled was a 92 440 panther delux. it was good untill i blew the clutch, and had to rebuild the suspenshion because i jumped it to much. i would not mined a new ZR with alot of suspenshion but it proulby won't happen, so polaris are nice and afordable! and go like heck!!! HE HE-Ouch to much speed and not enough picks hurt. look at my profile pict!!
If you are just replacing the head gasket, then there is no need to remove the jugs, and no need to replace the rings. If you remove the jugs to replace the base gasket, then I'd reccomend a light hone, and replacement of the rings.
you know, i hate to say this, but if you are going to replace the rings, i would HONE IT. get yourself a hone with FINE stones on it, and some kerosene. hook up your variable speed drill and go to work. if your unsure how to achieve the CROSS-HATCH as hotrod mentioned, goto your library and check out a book on engine rebuilding . honing is very simple, and should be done if you are replacing rings. it might not be a bad idea to check the trueness of your cylinders, using an inside bore guage and a micrometer, check the top , bottom for taper, and for trueness. chances are if your cylendars are out of round, rings will be of no use to you cause they just will wear out again. but if everything looks good, giver her a light hone, and throw her back togather. and YES take it easy for awhile so that the rings will SEAT properly.
Yea, i will hone it because i have to replace the hole top end (gaskets) anyway. i cleaned my carbs and they were filled with black chunks in jet to fuel bowl, and rust in the little fuel inlite? into the carb. i got the seat off and gas tank to try to clean it?(gas tank) i will be rebilding my sled this summer, gettin it tuned, new gas line, pipes, drage studes,
