Does anyone know what it would cost to replace all of the top end gaskets. Its an 01 grizzly 600 and it has an oil leak. If I'm going to tear it apart i might as well do it all. The guy i bought it from told me he just had the top rebuilt but its got a bad leak. Just curious on what it would cost to take it to a shop or to do it myself. Between my grizzly and my dads kodiak we've had tons of problems but i guess thats what happens when buying a used atv!
