[QUOTE="5twins, post: 622082, member: 156”]You probably don't need 4, 2 would most likely do the trick. Just don't move the bike between checking each carb. And try to get it parked as level as you can before checking any of them. I use a torpedo level across the front motor mount on the 650. I have some metal wedges I can jam under one leg of the centerstand to level the bike up.[/QUOTE]
I went through an ‘81 for a friend of mine. I set the levels with the bike on the stand running. Those nipples on the bowls are helpful. I want to reset mine the same way.
