Bad Knocking noise

[JoshLix]

New noise. I really hope its not a rod. before it started I adjusted my cam chain, It was making some noise so i tightened it til the noise went away. then rode probably 80 miles and this new noise came up. other symptoms was at idle if i reved it up quickly then snapped the throttle back down it would die. I will attach a video of the noise. Any Ideas?

Just had the carbs serviced, rebuilt and synced by a shop.
Did a oil change myself.
adjusted the cam chain myself.

Bike is a Suzuki GSF600S bandit (miles 16K)

I'm not familiar with the motor but the cam chain wouldn't need any attention at 16K.

Sounds like you tried to fix something what wasn't broken and broke it.

[P.]

Why adjust the cam chain. It's self adjusting. Assume you mean drive chain...

However just sounds noisy. Any leaks at the actual header pipes, most tapping would come from that area having a slight leak.

Here are a few things I forgot to say. I just did the cam chain because it was making a rattling noise from it that the mechanic mentioned and I heard. My cam chain adjuster is not stock it doesn't self tighten. I also forgot that the mileage showing is not correct. Also I just got this bike alot of mystery.

[P.]

So you took the cover off, measured it and adjusted....

Yeah, get the stock tensioner and leave it.

so I Checked all the valves and changed the clearances. I also checked the cam chain when I was in there it seemed ok and not to tight or anything. so i am starting to think exhaust. how can you tell if the gasket is bad?

[P.]

You need new gaskets now you've removed the headers.

[mudcow007]

that's the cleanest Bandit i have ever seen

if you have removed the rocker (to do the valves) did you "instant gasket" in the half moon cut outs?

if you didn't....expect oil misting like a bastard

[JoshLix]

Yes I put some gasket sealer around the half moons. I didn't check the cam chain timing because didn't know how.

Just for taking headers off instant new gasket??

[mudcow007]

You need these

[ZaphodBeeble]

When you adjusted the clearances, did you make sure each set of valves were adjusted when the corresponding cylinder was at TDC on the compression stroke?

Sounds like you may have overtightened the tensioner and taken out a main journal.

[JoshLix]

Still waiting for gaskets. Should be here any day. I will keep you all updated.

I attached a link to a you tube video of noise and how it sounds now. still there sounds a little better after changing exhaust gaskets.
