It would be a good idea if you plan on keeping the sled to rering it. Really it needs to be done around 3500 miles if you want it to stay in tip top shape and tune. As some guys will tell you oh they run great and I have 20,000 miles on it, it doesnt run like it did when it was new. The power reduction from the loss of the ring seal and then the piston wear happens over time, so its very gradual. The 2 stroke engine relys solely on the piston and rings to do the work as thats the engines valvetrain. So the piston is subjected to twice the beating the 4 stoke is. The rings wear first and reduce the seal (blow by)and then the piston begins to rock in the bore and this is what wears the skirts.
Sure, it will sound and run just fine but whats waiting to happen is the piston will break off the skirt from rocking in the bore and then the engine will be trash in short order, usually blowing out the case bottom from a pressure crack.
If 2 strokes would go high miles with no piston ring changes we'd have 2 stroke cars with the great power to weight ratios a 2 stroke offers, but you cant get away from that a 2 stroke relys solely on the piston/rings to do all the work. In this thread alone you have 2 guys telling you how great they run and how you dont need to do anything, but if you put a leak down test on their engines they would fail. The other big misconception is and as said "it has great compression yet", well ya,.. compression is just the measure of how fast the cylinder can build pressure but to check a rings condition, you need to do a leakdown. Thats what measures the rings ability to seal, so what youd measure is how long can you hang onto that pressure, not what the rapid build up is. If the 100psi leaks down in seconds the rings are not sealing good,=-blowby.
Just the other day there was a thread of a 02 srx with 11,000 miles that broke off a skirt and sent it down into the crankcase, this is what happens when the piston rings wear and the piston becomes sloppy in the bore, it WILL break off the skirts sooner or later, I promise you.
its your engine do with it as you deem is what you need to do.
