Backfire/Clicking

Sounds like more than a little back firing not a mechanic clicking!

Connect your carb sync clocks, they will show you the faulty cyl. (lean carb @ idle) by the vaccum drop.....

Danke Scirroco aus Ohio. Ich hab ein Deutsches Frau aus Stuttgart gegen meine zwei Kinder war da geboren vielen Dank für die Information  Thanks!

A quick test for leaking carb rubber boots.
Spray break cleaner on the carb rubber boots area (carb/cyl. head) at idle.
If the idle rpm is changing or going lower, one or more of your boots are leaking and sucking air. Than the engine or one cyl. is running lean that causes the piff-paff back firing sound into the air box.

I caped off # 3 carb atmospheric nipple and problem solved. Thanks TexasKZ 
YOU THE MAN 🧍‍♂️ 

I fixed the problem capping off # 3 atmospheric nipple. TexasKZ was right and I watch a video on that same topic today using carb cleaner or a propane port. I think carb cleaner is better so I’ll do that sometime this week. Bike is not clicking or backfiring now learning a lot on YouTube videos if I ever get back to Germany 🇩🇪 I owe you a beer 🍺.   Thanks Scirroco
