How many miles?

Hi I live in Vermont and have an 02 sxr 600 yamaha. I have just over 4500 miles on it. Got s new track on it last summer. Moderate use, you know fast and hard miles and sometimes taken slow. Easy riding. How many miles on a sled is too many before you trade it in or just sell it off and buy a new one?

If you take care of it, you can ride it forever, almost. 4500 miles, you're just getting it broken in.

I would be worried about milage until you hit 10,000. In your case, because is a Yamaha, I wouldnt ever be worried about the milage.
Yamahas pretty much run forever. Ive seen Yamahas like your's with 15,000+ miles on them that still ran flawlessly.

If it was a ski-doo it would be blown already! JK, your milage isnt to high, after you hit around 5000 miles check your compression, once its getting low you need a top end, and your good to go again!

It's a funny thing,the dealer will tell you that a Yamaha will go forever and it will as I've proved it myself but go to trade it in with more than 5,000 klm's or 3,000 miles and they really don't want it.I had 5,500 klm's on at the end of the first winter and he didn't want to give me even half of what I paid for it even though I got it for a good deal non-current.

Nonsense. Its a snowmobile, not a dirtbike. Ive got over 7,000 miles on my sled and the motor has never been apart.
This past summer I did a compression test on it and it still has 119 psi in the PTO cylinder (clutch side) and 120 psi in the mag side.

15 psi is nothing. Worry where it gets below 100 psi.

My dirt bikes get new pistons and rings every race weekend. I don't think I've ever put a set of rings in my sleds. Why? They're stock motors and as long as the compression stays above 100, and they're even, I don't really worry about it. If I ever see 100, or they're uneven, then new pistons and rings are in order. No sense doing just rings, as long as I've got it apart, might as well drop a new piston in it too.

Wrong again. Even when new, compression on those sleds is only 120-125 psi.
You need to stop believing everything your dealer mechanic tells you.
As long as the amount of compression is 100 psi or more and the compression is fairly even from one cylinder to the next (within 5 psi), there is no reason to do a rebuild.

I agree with octane, but it seems most sleds start to drop alot of compression after 5000 miles.

I had approx. 6,000 miles on at the end of the second year and it was running just as good as it did when I brought it home,so I can't see dropping probably close to $600 in parts(pistons,rings and gaskets) just to freshen it up.I doubt you would notice that much of a difference.I would be more inclined to take the $600 and put it toward another sled.JMHO.

Basically what everyone is trying to tell you, is do a compression test. My srx has nearly 5000 miles and the compression is still around 125. So as long as the compression is around or above 120, and is pretty even, your good.

You guys that think compression readings are all that are needed to determine if a topend rebuild is needed crack me up. The only true way to determine what is needed for a topend rebuild is to measure the piston to cylinder wall clearance. Many, many engines have had excellent compression and ran just fine up to the point where they break a skirt off due to excessive clearance. I see this every day, shattered pistons and broken cases come through my door at a steady pace. And I'm not a dealer mechanic- no dealer is willing to pay me enough. As usual KC Cats is providing good advice.

I'd believe a leak down test over a compression Anyday.

Well said Jerry. A little preventative maintenance goes a long way in my book

Ok Guy's, Thanks for all the feedback. Last season I put a stud through my heat exchanger. Never Never again will I run studs. I picked up a new track, Kimpex, 3/4 inch lugs. Love it. Better grip than my old track. Well, I got the exchanger fixed and checked out my water pump. Needed a new O ring. New track. Ready to ride. 4600 miles on it and still stong as ever. Still get's my juices flowing starting it up and hearing those Triples roar.
