You need to end up with .030 clearance
as an ideal. Standard is often about ..040" the new HD gaskets would give you a clearance far in exess which will run fine but not quite as well as you could make it
If your not measuring the squish you have to go safe, and go bigger than maybe!!
Thats what HD do for the production line.
.040" with a .016 base gasket is the old standard size and has always done me fine.
Im running that now giving me a 30 thou squish but I think a previous owner has taken a few thou of the heads as they gave 40 odd thou on the last bike I did.
yamabond has a very good rep' but it will have a clamped down size of "not-a-lot" and I would not
want to guess the clearance between head and piston.
On a teky point. Its not known as piston slap, thats something else, its piston clearance
were concerned with here, which stops the piston hitting the head if run to hard when cold.
Piston "slap" is when the skirts of the piston rattle up the side of the bore.
I prefer HD gaskets but I guess they all can fail for some one at some time.
Ive just gone HD base and cometick head. Far to early to say weather the cometick will serve me well.
If I have anouther base leek I may take Poolbizz's advice and get some yamabond to put on the base gasket.
I think you have gone in worrying loop.
Get the book, tools and a set of gaskets and have a wk end listning to the radio geting intermet with your bike.
and dont forget to tell us how you got on. Enjoy it.
