Flashing tach

[Scarlet knight]

I’m confused between the two style of blinking lights on tach.. led to believe it’s the low rpm warning, bike has a hard time keeping from stalling out. Burns plug in front jug but rear is firing just fine.. not even a week old.. new battery as well. Any ideas? Too lean? Can’t smell any gas in the oil..

Blinking tach = low idle

Re-check spark plug gap and carb settings.

Gap should be 40

Gap should be 40

Gap is 2 seconds from bike in your line, one sec from other line... Oh spark plug----
Oh and that gap is 0.040" to be technically correct -- the best kind of correct (futurama reference for those that don't know)
