i changed the cam over today and checked again and got the following readings...

piper t2 cam: cylinder no.1: 60psi,the rest made around 100psi

standard cam: cylinder no.1: 100psi,the rest made around 140psi

now cylinder 1 is still down 40psi but why have they gone up using a standard cam? im ganna change the rings this wednesday anyway but is 40psi down on one piston ganna make much difference in power??

cheers lads
