FXS BLEW REAR HEAD GASKET NOT A BIG JOB TOOK THE REAR HEAD OFF THOUGHT Mmm FORGED PISTON .....
ORDERED A GASKET SET THOUGHT MAY AS WELL DO THEM BOTH TOOK THE FRONT HEAD OFF AND FOUND A CAST OEM PISTON ???
DONT THINK THATS A GOOD IDEA THE DIFFERENCE WAS A 100gms BETWEEN THE OEM AND THE FORGED NOT A LOT BUT AT 80 MILES AN HOUR ITS A WONDER IT DIDNT KNOCK THE ARSE OUTTA IT.. GOT A NEW SET OF PISTONS TO GO IN, ITS ON 30 OVER, THE HEAD NEEDS A SKIM GOT SOME BAD MARKS AROUND WERE THE GASKET BLEW MAY BE THE REASON WHY ITS HAD A PISTON IN THE BACK BEEN RUNNING A BIT HOT.
DID SOME SHOTS OF BOON'S A65 CAFE RACER
