You guys want to get rid of intake o-ring leaks? I ordered new o-rings took one look at them and put them in the trash. Went to the auto parts purchased a roll of gasket material for about $7.00 and made my own gaskets. If you look at the sealing surface between the head and intake there is plenty of sealing surface. Works good for me.
Good luck guys
Or just put Viton o-rings in and be done. I’ve done several bikes including mine over the years. Perfect and forget about it.
