Mach 1 valve clearance

[nalimugmug]

Hi,

Hope your all safe and well at this troubling time-

Simple question, are the clearances checked hot or cold?

The amount of information to be found in this site is incredible, thanks to all of you who contribute. This might sound like a strange ask, however, does anybody have a pic of the late DewCatTea Bob?

Thanks and take care

Bob

Hi again,

Posted on this site from the The Ducati workshop manual

Inlet .15mm
Ex .30mm

Mick Walkers book, restoring Ducati singles

Inlet .15mm
Ex .25mm

Which one should I go by?

Thanks

I used 5 and 7 thou back in the day and the bike was timed at 104mph ,but if you use all the revs a lot the clearances can close up as the valves hammer the seats so you need to keep a check on it.
