Shaving the cylinder head

With a cp 11:1 piston what the maximum i can shave out of the head to don't go past 11.5:1 and also without slamming the piston in the valves. Thank you!

Decking the head, that's a good question!

One thing you might want to look into is the timing chain it is a serious week spot on the 700xx motor. I raced with Matlock for a couple of years and his broke three times that I can think of. Alba racing sells a kit, but I am pretty sure its just the gears, chain, guides, and tensiener out of a 650r bike motor. You have to replace all the parts, but size difference is very noticeable, and worth doing.

Yes thank you for the advice/info. I guess I should do that upgrade now before it gives out on me.

Welcome to the club, glad to have you and your knowledge

why do you want to do this? you deck the cylinder, not the head, you should'nt do this unless you head is warped.....or unless you want to reduce the combustion chamber size.

The idea is to get more compression, about 11.5:1 with a cp 11:1 piston

Correct...and you do that by decking the cylinder not the head.
