I'm not ****ed off, I just want to give up all that 5h1t...

The 600 engine is making a strange metallic noise, just like if the pistons were knocking to the barrels... I'm sure I already heard it on another Monster and thought that was not a big issue but it seems a friend of mine is worried about that... What do you reckon? The bike is waiting to be dyno'd...

I think I said I wouldn't be ready about 2 months ago, I wish I was wrong...

You do get a lot of piston slap on the 583s especially when they have a few miles on them. Not sure when you should start to worry about it as they all seem to do it after a while.
Bet AK has more of an idea than I have

Mine sounds like it's about to spit a piston straight out the side of the engine, but it's working just fine Let them dyno it, better it goes pop in there if it is something terminal!

[Tonio600]

Thanks you both for the advice. I told him to go ahead. If that engine must die then I prefer it does it on the bench instead of on the track...

Kev I'm trying to sort out my forks problem thanks to Phill_h, thanks very much for your offer but unfortunately I wouldn't have had time to go to Oxford to collect yours...

Agree with all the above - my spare engine (!) sounded like a bag of spanners. I whipped the head and barrel off, everything looked and measured ok so I put it back together again and will worry about it when it explodes!

Are you finally sorted with forks, as I have acquired a spare pair that just need new seals?

Not sure how relevent this is but the new bike clattered like a good un a few weeks ago. It went and had the valve clearances done and came back loads quieter with no rattly clanging noises.
Just an observation of mine tho Dunno if it's supposed to make a difference or what really
