I didn't replace any gaskets. Only 1 seal. The magneto side thin seal because it was installed a little crooked. I haven't had any leaks in over 1200 miles now.That is actually where I got mine due to a lucky windfall I came into just enough cash to purchase the kit. I figure that I will be tinkering around with just setting it up and learning about it long enough to afford some needed upgrades. Biknut would you recommend replacing the gaskets right away or will they hold a while? I plan on checking everything you recommended but am not sure about new gaskets right off the bat.
You'll need to retorque the head bolts a few times at first. I've been keeping mine at 125 in lb. Make sure the acorn nuts aren't binding on the cylinder studs.
