I ordered the cometic c7070 top end gasket set. It says its a 72mm according to the cometic website. Its all they sell I think for the 85/86. Will this be a problem? I got All Ballz crank bearings and a complete cometic gasket kit c7070 and c3363. I also got 3 different types of crank seal seals. I got cometic, all ballz, and s&k. Which ones would you use?

.030" = .762mm
So you're at 70.762.
The 71mm gaskets should be fine.
grab a 71mm piston. (it will be +/- 71mm so be sure to give the piston to the machinist to bore too)

Its bored .030 over. Do i need a 71 or 72mm cometic gasket kit? Its shows different sizes.
-
usually go with OEM for seals, gaskets, and bearings.
I've used all balls and cometic and had good luck too.
-
The complete oil seal kit i have is a k&s. Are these any good and worth using?
-
Ok, thank you Q. Do you recommend a particular brand of bearings and seals. I have a cc seal kit already. Not sure of the brand, its definitely not suzuki. And what brand of gaskets. Just trying to fix right and flip it.
-
Typically it's just the bearings but it's worth inspecting since you're splitting the cases.

Bought a 86 has new topend already installed. He said it was sucking cc oil into the cylinder. I pulled the stator off and can just barely move the crank up and down. I know that is a sign of worn crank bearing. Guessing probably why the cc oil seals are bad. Does this mean my crank is also bad? Or can i just replace the crank bearings and seals, that is if the connecting rod is in good shape to the crank. The guy i bought it from said it was ok. Lol
