Yes, you will need a whole set of gaskets. Oh and uh, get some razor blades to scrap off the ole gasket pieces when you take the motor apart too. good luck man!!

Yep!!! you need gaskets. Compare individual prices to the top end kit, I think the kit is a bit cheaper. After the shop is done with the cylinder be sure to run scotch brite in the cylinder, and then wash it throughly with hot water and soap. Be sure to set the ring gap alot of shops don't do it for you. :cool:

if you go to CTracing.com , they have a whole page dedicated to the putting together and breaking in of your motor. its good stuff , you should read it

did you have your valves adjusted? when the valves get out of whack enough they knock

if you are boring it, then moto-man.com has a piston kit with gaskets and all other hardware for 104.99.

I would check your vavles first before you do a unneccesary bore and hone. Your vavles will knock if they need adjusted or went bad. I doubt you need a rebuild.
