Can I do this so that my 08 has dual ring pistons? My brothers sled is a 07 and mine is a 08 and that is the only difference between the sleds and his runs way better.
07 700 pistons in an 08 700

Should be able to install the two ring 2007 700 Dragon pistons in a 2008 7000 Dragon. As the my Poo dealer installed two new 08 700 Dragon single pistons in my X old 07 D7, then burnt down for the second time in 100 miles!!!!!!!!!!!! I traded in to Poo dealer as my 07 D7 turned into a slow poor running DOG!!! The compression dropped 5 psi on the mag cylinder, then burnt down on the new owner in less then 100 miles. I tried to tell Al and Dean that my 07 D7 Dog was going to burn down, engine temps went up to 147*F and much slower, 90 MPH Dog. I told the service manger Dean that most likely it had weak pistons and the typical 07 "BAD/Weak" "'Stator" that would hurt performance. Service manger checked every thing out, said no problems with my 07 D7 Dog. So I traded it in on a new 09 600 CFI 4 Switchback, also a Dog as it would only go 79 MPH on a hard packed lake or road. Many poor factory set-ups on my 09 S.B. 600 CFI 4!!!!!!
Suggest to check compression with cold engine and with engine warmed up to 125*F. Then remove, clean power valves, inspect pistons thru the open power valve holes in cylinders. If the compression varies more then 5 psi (Poo warranty spec is sad at 10 psi difference) between cylinders, pistons scared, etc, install two new 07 Dragon/Polaris or the new coated Wiseco two ring pistons.
If the compression is approx 125 psi on each cylinder with a warm 125*F engine, pistons are good, do not change.
Most slow 2007 600cc CFI 4 and 700cc CFI 4 Polaris sleds had the "typical weak stator", many back orders on stators in 2007, improved stator plates in 09!!!!
The stator plate assembly usually checks out OK on a cold engine. On my X 07 D7 it would loose power after approx a 30 minute run. If you had a poor dealer like I have, suggest to trade your D7 Dog in on a different sled!!!!
Was the Dumb *** Poo engineer that decided to go to single ring pistons in the 08 700 and 800 CFI 4 engines ever fired???
Most Polaris engineers are very, very sharp!!!
Good luck, you will need it; Rich

I had an 08 700 155 that got sick at the end of last year and it had double rings in it from the factory. I know the 08 800 dragon had the single ring, it case that helps.
