I'm working on timing the cam to the pistons.
I know that both pistons move in unison but fire simultaneously so there's no question which piston should be TDC, but rather which cylinder should be in its compression stroke when the cam notch is upright.
I first thought to assume it would be cylinder #1, but being that the bike is of Japanese design, it could be #2 for all I know.
Thanks in advance.
