What do you all use for a timing light on a R1150RS 2004? Just changed the HES and its running like poop. Idles only after a few starts. It pops and farts and won't take any throttle input unless blip it up. New HES was put on the same mark. Got it to idle a bit and cylinder head temps were even +-. This was a die going to breakfast. Changed fuel filter, one quick disconnect. Plugs were changed last year.
