Hello,
Its been a long time. My engine has been away for a while ie new main bearing bushes(bronze), crank balance, Combat oil/breather modifications and cam bushes. But the engine builder doesn't like the look of the cam for a number of reasons the key slot looks buggered and there is a nasty knock on one of the cam lobes. The engine is a combat so I suspect it has had an explosion at some time or other.
My delema is what cam do i get. Im leaning to the standard cam or Mega Cycle 560-N-R as Im not really into top end performance. As well, I noticed that Norvil voids warranty if you dont buy new cam followers. My engine builder says I dont need to buy new cam followers as they are in good condition and they have a flat profile anyway. Im inclined to believe him as he quite experienced in building race engines for classic bikes. As well who should I buy the cam from as I have read that quality of cams can differ.
Oh and incidentally has anyone put carrilo rods in their engine, the Builder notice that there is a bit of play b/w the rod and the piston pin on my new rods. He has noticed this on other carillo rods and suspects it may be normal and possibly this would occur with the standard alloy rods through expansion. Does this sound correct or do I have problems. The Pistons are a new set of italian GPM(or something like that)
Regards Bryan
