I've been working on my recently purchased kz440 for a few weeks now. The carbs are cleaned, new spark plugs etc. I'm getting this odd snapping sound coming from the motor that i'm unsure about. This sound was not as apparent when i viewed the bike for purchase. I had the bike cutoff on me (gradual loss of power to eventual failure and would not start back up) about a week ago. I've since been able to get it going, and it starts great, which i think rules out battery/charging system issues from the cutoff. However, ever since then this knock/snap has gotten worse. If someone can listen to my video and give me somewhere to start that would be fantastic. I've been reading up on it, and theres about a billion and one "funny noise" threads, just though a video would give me a better response. Thanks to anyone who can assist.
Also, at about 2-3000 rpm, i'm feeling what appears to be a miss if i hold throttle there. It happens without fail, but once i'm past it it's smooth (other than the snap sound, which is throughout the powerband)...
