This is a photo from 2009 (bike and my girl with pink bikini), with footpegs I started in May 2012.
I still bought and changed for other than I made those with whom I would be satisfied.
What I make NOW is MARK V. in preparation is the MARK VII now.
MARK VII



MARK VI is ugly :-)

sleeve could be loose

I have heard of a few with the liner coming loose and causing a exessive rattle.

I once had a sleeve that was pressed in too low or a bad resleeve that allowed it to be loose which resulted in head gasket leak. The bike still ran but took an outside observer to see the blowing fumes past the head gasket. bike had a fried head at first, possibly from that escaping gas overheating it. Resulted a loud popping sounding like a head exhaust leak when revved.

What I'm getting at is that it seems the sleeve would settle into a high or low position if loose.

I've also improperly honed a cylinder resulting in piston slap.

Having said that, the noise on your video IS way too excessive. To me it sounds like someone (you) might have seriously messed up the valve clearances due to not correctly following procedure.
It made the same sound before and after i did the valve clearances. Which makes me think its something else, I was reading some more online, and alot of people say the cam belt tightens (or is spos to rather, if its not totally slacked out) when you rev the bike, so the noise could go away if it was the cam belt.

Watching these video's someone posted, but they are not great for telling which bolts to remove ect, so i think i'll take it to a local small time shop, and have them there into it for me.

Just asking what might be a silly Q
I though cam chain noise would be different to valve clearance and piston slap
If I'm hearing correctly on the video, it is a distinct ping type sound that continues when revved
I'm no expert but I'd be interested to know the outcome if this

This is where i'm confused Also... I really wanna Tear into it, it would be the 1st time I ever Opened up a 4stroke motor... Very curious what area's inside there need tending too. If i can find a detailed link, i might just give it a go.

Also, is removing the motor from bike needed to remove top end ?

I haven't done it, but apparently not. There is meant to be enough wiggle room once tank, coils, etc are off to get the head and the barrel off. It's only the crankcase that needs engine out.

No it is not necessary

Can you pinpoint the noise ? valve cover maybe ?

Maybe just remove vale cover and have a look

thinking like rocker arms ?

I'm just thinking, if you get on ok with your local bike store maybe you can ask the mechanic to give his impression so you have some idea before opening up

The first time I was listening to your recording I said it was way too excessive. I guess the feel of the sound out of the computer did not let me feel in well enough. Also (at first time listening) I heard a much stronger pronounced high notes ticking for whatever reason. Perhaps some speaker quality issues or maybe it was too early for me in the morning. BTW: I challenge others who posted here to listen closer again as well.

Indeed, now I listened to it again and it sounds very similar to the sound that my engine is making for about the past 30.000 miles.

It IS certainly (the for the XT600 typical AND for the XT600 harmless) piston slap, as mentioned earlier. If you listen to it carefully, the noise should be a bit different (somewhat louder) in cold condition and would get a bit better after warming up, although sometimes when the engine is really hot you might hear it even louder.

It is all normal = no worries, ride the bike, ride it until the wheels fall off AND don't let anybody tell you othervise!

If the engine runs strong and does not use more than 1 quart oil per 1000km, then I would under NO circumstances open this engine, as any attempt (especially by somkeone for hire) tying to fix this might very well turn out to be the END of your engine.

I would love to hear/see a video of yours running as a comparison.

Oi

How about a real problem that stops the bike running!!! i asked a question on this thread yesterday, regarding my xt600z, but it seems like everyone wants to comment on a bit of cylinder noise, i may be a newbie on here, but have been riding since 1981,

Thanks
