head gasket question?

[zilla rider]

hey guys i have a question about my head gasket. its leaking and it is a new gasket. if my bore is 87mm. what size gasket should i use? my exisisting gasket is leaking right now and it is burning coolant, and yes i did use sealer. it is a k&s gasket. i heard that copper head gaskets are really good for that kind of problem but i dont know much about them, like if i should use sealer on it or not. if you guys could help me out or give me some suggestoins or pointers i would really appreciate it. thanks.

Ive never had luck with k&s gaskets. Get a copper gasket or an oem. If you really want to eliminate that problem get your head cut for o-rings

What Size Gasket Should I Use For An 87mm Bore? Should I Use Sealer On A Copper Gasket? And Where Can I Get A Copper Gasket?

my zilla is bored .100" over and I am using a stock gasket. haven't had a problem with mine yet.

yea u should still be able to use stock gasket but i dont think u should have to use a sealer but thats me i never ran a sealer for a head gasket and if u need a cheap head gasket or repair one on a junker use alum. foil i have tried it and it works but only if it is air cooled cause i blew my piston cause i leaked a little bit of coolant into tha cyl.

I am not sure if I used sealer or not, i don't think I did but i has been a while.

When using copper, sealer is a must. I have never used any sealer on regular gaskets, been fine. I checked the torque for the first 5 or so rides and been fine ever since.
