I got this 88 K5 motor/bike in Pieces, I rebuilt the motor compl. splitting the cases and replacing all seals, reeds etc. the cyl was Sleeved so I had it bored and honed. I assembled the motor and finally got it Fired, ran it for about 20 sec when I noticed Coolant leaking from all around the head gasket. I used a ATHENA Gasket Kit and there Head gasket, any advice would be great on what I should have done or should do to stop this. Wondering if anything I Listed below would help
1. Possible Warped Head or Cyl??
2.Crap Head gasket or should have used a sealant with??
3. Lap Cyl and use Cometic head Gasket
4. #3 with sealant??
