Fixing the XT660 problems - English | Working on my Yamaha

For a good few weeks the XT660 was having problems, stuttering and misfiring in a certain rpm range.
Across a few days we tried to trouble shoot the problem by just checking all possible problems.
Not everything has been filmed, but some of the bigger works are shown in this video, including the problem and the solution (for my situation).

I went through your videos and maybe you can help me out.
I’m working on my sons MT-03 660 with an aftermarket exhaust. Sounds great, but the plops are rather frequent and very loud, even with the best reducing db killers inserted. Hence I wanted to block the AIS with a simple fix by blocked off the AIS in way of the air intake tube as I found on the internet.
When disconnected the rubber tube at the air box, but not yet blocked, I started the engine. Once started, I blocked the tube with my thumb and due to the vacuum the engine immediately stalled.
Have you tried this on your XT660?
Your comment is much appreciated!

you had opportunity to really help community by testing them one by one so we could pin point what is the issue but no you have to chage them all at the same time

Was your ignition plug black or normal color? Did it depend on outside temperature?
