To the OP..... I think your question about aftermarket replacements to the OEM parts was a good one. I think it would have ended up being somewhat of a punch list of things that could or even should be replaced. Thumbs up!
However, and I mean this with no disrespect and this is not a personal attack. I gotta say I'm not quite sure I've ever seen a thread so badly Hijacked with the most irrelevant and useless information.
Now, if you had originally asked how can I service my sled to make it last 99,000 miles only to have it blow up shortly thereafter so I can submit an engine claim, then put this brand new engine in a chassis that's been completely replaced or repaired 100 times over!
See what I'm getting at here? Who gives a rats
@SS about the 100,000 mile warranty! Most of us would have to live to be 150 years old to put that claim in!
So just put the products in your sled that just plain work and are proven. Isn't that why we are posting here in the first place! This site has a collection of experienced riders from all walks of life that go out and try new parts and set ups just so the less experienced owner can benefit from this knowledge right away. Take advantage of this information and enjoy your sled knowing it will perform to the fullest and you will be prepared to make that sled last..... well........ NOT 100,000 miles!
