    02 Polaris Virage TXI Burnt piston after 12 hrs?

    Hey guys I need some feedback. New to the PWC seen just purchaced a 1200 direct injected polaris with 12hrs on it and the #3 cyl has a tosted piston? What could have caused this? Can I just boar the one cyl and replace the piston? Thank in advance for any help!

    I got it with the problem previous owner claims to know nothing about it It had double platnum plugs in it wich I thought to be a no no in a 2 stroke. #1 and #2 pistons look fine?

    You ll need to pull down the cylinder and take some photos and let you know what to do to help stop it happen .Can you get the spark plug numbers for us ?also need to look at the plugs .Can you take photos of the ends that go into the cylinder head ?.We need to check fuel pressure before you start it after the repair also .

    Cheers

    Thanks for the help Bernie! I already took the cylinder and piston to the machine shop I threw the Platnum plugs away. With the direct injection arent all the injectors all on the same fuel line because #1 and #2 plugs look like they were burning a little rich. Am I going to bee OK Just boaring one cylinder with a weight matched piston?

    Did you take photo's of the damage so we can possibly prevent 2 cyls in 24 hrs ?Need to bore all three barrels or get a good barrel from someone and keep piston the same size .Need to keep the Cylinder volume the same ..Plug numbers ?We need to find the cause of this not fix the damage and then do it again by not diagnosing it properly
