I have bought 2005 Electra X some time ago. Previous owners has installed some tuning parts.

-535cc cylinder and accralite 1320xc87 dome headed piston
-Amal 932
-derestricted exhaust
-HC cams?

What is compression ratio with this piston and can anyone identify cams from picture, are they Hitchcocks cams?

Are cams supposed timed to factory markings with this setup?

Also there was that M.A.P cycle enterprises steel con rod document in bike service folder. Is there even available thatkind conrod to Enfields AVL engine?

I have green tci installed but have that "performance tci" in spare. Should i install that too or it is intended to stock cylinder and cams?

These are our hosts' Electra-X performance cams, I would expect them to have timing marks.

I don't know the compression ratio of that piston, but it's from one of the earlier kits, that latest version has just a flat-topped piston crown.
