I've got a stock 10 that I rebuilt this year at 3200. I wish I would have done it sooner. One ring was flaking, that cylinder had some minor scouring right above the exhaust port. Both sets of reeds had some chipping, one was missing a small piece on a corner. I'll be doing it at 2000-2500 from now on.
I have a 10 that has 5006 miles on it has never been opened up just gonna c how long it goes cause im curious (yes keyboard jockeys I know its not smart and may cost me just want to c how long it goes)
You would be surprised how far it will go. I have seen several with over 7000 that have not been touched engine-wise. Contrary to post #4 belief, you do not need to rebuild an M8 at 2000-2500 miles. You are wasting your money..........M1000 yes, M8 no.

I just freshened the top end over the summer for routine maintenance with 2400 miles and I am GLAD I did...PTO side piston skirt had a 5/8" crack in it!! All stock motor too. Now 2 rides into the winter I blew PTO side piston which took out the cylinder wall. Replaced all and seized up 3 miles up the road again! Discovered air bubbles in the oil feed line from the pump to the intake plenum...Oil pump took a **** which coincidentally caused damage to the gear drive that turns the oil pump and the water pump taking out the seals. Not cool!
The way I see it you should put in new pistons whenever you loose confidence in your sled. It sucks going out for a ride everyday wondering if today will finally be the day your sled blows up.
Anyone else have an opinion on it
07. M6. With 3,000
Any comments. I was wondering
Also. Have done my dd drive on 10 m8 ( bearing) but not on m6
I was thing of doing this weekend... To inspect....all I have done on the m6 is change oil.
Much difference in doing the two?

It's all relative! How do you treat your machine? Good warm ups? quality oil? periodic rest while pounding the mountain?
or is it... pinned before the D-ring hits the console and never let off? no ice scratchers? only service the clutch when it fails? use what ever oil your riding buddy for the day is pouring?
IMO 2000mi. in the mountains, is plenty of abuse for any 800cc. piston on any brand of sled. Can you go farther? probably. but at what cost?
Preventive maintenance is way way cheaper than waiting till she blows!

5400 miles on my 11 CF 800. Pistons where were worn on the top on the exhaust side and reeds where shot.
