My cylinder is done and ill be puttin the bike together over the next couple days.  My questions were:
1. I am using an afm base gasket and will smooth down the ridge between the case halfs under the reed valve. Do I use any ultra gray in this area or am I good cause im using afm?
2.  What is the proper ring end gap?. Im using an 86.5mm wiseco piston.
Thanks.

Thank you sir. I thought I heard somewhere that afm gaskets didnt need ultra gray, bit I couldent remember.  The extra protection cant hurt.

carb cleaner.

Ok, so im gonna lightly sand the areas where the case halves meet, clean the surfaces on cylinder and cases with rubbing alcohol, let dry, then use a little ultra grey and the afm gasket. That sound right to you guys?
Thanks for the replies, im being a lot more meticulous with this quad than on prevoius top ends ive done on blasters, banshees and 250r s. Ive never had problems with prevoius top ends, just trying to cover all the zilla weak spots before I go and hammer on this thing.

Gotcha. I was referring to lightly sand the burr where the case halves meet. Its barely enough to catch a fingernail on, but its there. A lil pass with the scotch bright should clean up the surfaces themselves.
Another thing im gonna try with leak down testing is an expandable bladder used for clearing plumbing drains. Its supposed to handle up to 100 psi.  I will use it to extend into the exhaust port past the pv, pump it up with 20 or 30 psi and see if it seals. Then do leak down with hopefully no question of air leaking past the pv into the tranny. Ill let yall know if it works or not.

A knife sharpening stone can be used to dress the flat mating surfaces, but go easy on the aluminum!

yea 1211 is great but a little messy.  It's all i use but i reckon ultra gray is very similar.
