ok so i’ve got a longer one, to start off i’ve got a 2005 fz1. recently after a long group ride the bike started making a weird tick, so i investigated and found a loose chain on exhaust side. some people said its normal, most said its not, i didn’t really know what to believe but i personally thought it to be the noise from the chain slapping around. i did some research and found the cct tightening trick so i tried that, did the whole thing and put it back together just to find it has a worse noise now. while i was in there i deleted the ais aswell, had the wires out and changed the oil. im kind of worried its rod knock
oil was a little questionable, but i must mention, second gear dogs are slipping so metalic looking oil is kind of expected at the moment.
back to timing, before i did anything i wanted to make paint marks of where the chain is up top, so i pulled cover then put it back on. after the first startup with the worse noise i suspected it might’ve been off a single tooth, so i pulled the valve cover and it was infact off a single tooth from that mark i made on intake cam prior to touching anything. i fixed that last night, retightened the chain with all slack on tensioner side (intake) and slapped it back together expecting it to be good. but my luck the bad knocking noise is still present.
i did tear a plug boot up top above the cover, and tore the wire out of another one by mistake so the slight chance that has anything to do with it? and i ended up just threading the nipples for the ais for the exhaust, incase that has any value to the topic.
i include 2 clips, one of the noise before i touched the timing, and one after. you can tell the difference.. im wondering your opinion on the noise, is it bad timing? maybe bent valves? definitely rod knock? i ran the bike for about 3 minutes total while it was sounding this bad to try and diagnose. thanks for your time.
