It was oil cavitation , I’m in Australia I’ve spoken to s&s by email and rollies here ,they rang me and told me not to ride it had to tow it after 400 km breakin they fixed the. Cavitation and an oversized timing cover , but the rattle from first ride is still there this has only 800 km on it I’m just trying to solve the problem not ragin on anyone, ive spoken to Tom Hampton s&s about this and did as he asked took to rollies! They didn’t attend the noise in fact pretended it’s not there i thought fixing the cavitation would fix the problem not so ! Tom don’t even reply to my emails now ! Guess it’s hard distance wise ! And noises Hard to describe , to me it’s like real loud pinging but not under load and yes I’m no academic ? It’s a brand new motor complete! I’m old school mechanic thought I’d give the v111 a go instead of another rebuild ? I’m sorely disappointed ! The rattle is at cruise , it comes and goes but is quite loud at 50 -60 mph non existent at idle , it doesn’t sound like lifters to me ! Seems to come from rockerbox ! Cheers to all !
