ineed help with my cr125

[johnbishop]

I have just bought a cr125 2003 model it has had a new piston fitted when i got it but when ever try and kick it up i get water out the exhaust any one tel me what my problem could be first timer here

Sounds like the head gasket may not have sealed properly Does it start at least or you are just kicking it and coolant is coming out without it running? If the piston was just fitted I'd bring the bike back to the shop.

as i am kicking the bike the coolant is coming out the pipe without starting
