06 busa Cranking but no start

[202mphbusa]

Well I synced the throttle bodies after I changed the plugs an it ran great
took it for a couple rides no problem excellent trip then yesterday I tried get a ride in an it start fine an strong but it sounds like a spunt bearing or something just my luck the bike has 40k miles on it
I will post a vid tomorrow

Bet the plug that had the closed gap is the culprit

Yea that would be cyl number 4 do you know what caused that what does that mean that it spunt a bearing an do you have to split the case to fix it
it’s definitely knocking at idle now
