sunbeam s 7

[john_sunbeam_s7]

i own a s7, and its complete restored. still i have a sound up, in the cilinder. i dont know all the specific engine details, what is changed and what is still original.
the sound is like metal parts, in the cilinder/ valve  area,  shaft is original. valve settings are new, maybe the chain tensioner, its a real loud sound of metal
who can help me out?

SUNBEAM S7 & S8 NORMALLY ARE EXTREMELY QUIET MECHANICALLY.I HAVE OWNED AND RIDDEN BOTH.
THEY DO OVERHEAT EASILY,ARE NOT VERY POWERFULL
AND THE SHAFT DRIVE IS WEAK.BUT,VERY INTERESTING NEVER THE LESS.FOR THE EXPERT OPINION  TRY   SUNBEAM@STEWARTENGINEERING.CO.UK
