Then a second video trying to show it better because of the BS he was hearing from the internet. If I were him I would just not bother trying to share information out on the internet anymore as these kind of responses really make it hard to want to do it!

The path the air leak shows in his video will leak from the combustion process much faster than the **** ant 12 psi he used for testing!

It's just another problem that the M8 is having, just like the sumping and transmission transfer. Does every bike have it.......... NO, but NO bikes should be doing it!
