I was sledding last week end and my buddy was getting smoked by 3 xcsp600 .... this is'nt right !!!  found his exhaust valves where stuck closed ... this is a brand new sled . What's up with that ?

You should clean them after 500 miles after the sled is new (at least).  You break the sled in on the "blue" oil and that leaves carbon deposits.  After you first tank of oil when you burn the synthetic, you shouldn't have much of a problem.  Just check them every 1000 miles and see how they are.

Are you sure the 600's are all stock? My 02 600 with some clutch work will beat a stock 800 quite badly. The 800 out of the box turns too high rpm and dont make that much more power than a 600 at 8200 rpm or higher.

Well they have V-forse reeds and cans on them , but that was it .....

the 600 seems to have alot off go in them .. how do the xc 700 do are they got much go to them

Depends how far you raced those 600 are jumpy out of the hole so maybe your buddy didnt have enough time to catch up with them

Out of the hole the 800 took them .... but at 90mph the little pack of wolfs screamed past him ... man I'll never forget that , wish I could have taking a pic

Afriend of mine has an 02 xc 700 and it will run with the 800's all day.Nice sled.

I'm also having problems with sticky valves. I tried a different synthetic oil and it didn't help. Also turn down my tps to 4vdc. I will figure it out!!!    2002 xc800.
