Anyone out there know what the valve timing is on a 500 Superfast or where to get it?
To remove this ad click here.
Bluemel lists the valve timing as follows but I can't be certain it is correct
inlet opens 27 degrees BTC
inlet closes 65 degrees ABDC
Exhaust open 74 degrees BBDC
Exhaust closes 16 degrees ATDC
and cold valve clearence .15mm intake, .2mm exhaust
You can always have a look at the flywheel and see if those numers make since with the ones stamped in the flywheel.
As per Factory Bld Sheet FOR 6041SA factory designation for SF was SA on build sheet
D = AA 26/65 S = AA 26/65
CS 73/15 CS 72/16
Thanks guys - much appreciated
Malcolm, how did it turn out?
Did you have to alter it to get it to run smoothly at idle?
Not finished yet, but don't expect any problems - easy engine to tune
