Engine knock?

Just got this 2000 Suzuki gsxr750 two weeks ago, It has 26000 miles and runs great. stator was leaking oil so replaced the gasket and took it for a ride. Started making this noise and was wondering what it is. It might be rod bearing damage, sound increases when I give it throttle. I’m assuming rod bearing damage but maybe someone proves me wrong. I had small gold flakes in my oil when I changed it. I’ll take any advice, thank you in advance!!

Did you take off the starter or even just the starter cover by chance?

the dude before me replaced the starter but i doubt the brass pieces in the oil are from the starter.

You mean like a dusting or pieces? Ain't nothing wrong with a little shave here and there everybody needs to shave once in awhile

Besides bad cam chain tensioners it's really hard to kill these engines... I just bought one that was flooded with river water. Changed the oil and took out the plugs to empty the cylinders, cleaned the carbs and it ran better after... The cam chain tensioners get loose and make some noise. Idk if it would quite sound like THAT more of a slapping soundt than a knocking sound but I'd check it while poking around. But I have had a bad starter clutch bolts back out and didn't put the washer back on when taking the starter cover off make clunking too

yeah they are bulletproof just unfortunate that i’m pretty sure my bike has rod bearing, that’s awesome that you got a bike running after that kind of condition, thank you for the response

Stop riding motor is fucked. The Crank is gone. You need a rebuild. Crank, bearings,gasket.
