High Cylinder Head Compression

I can find nothing rattling or loose except the cylinder cowl is a very tight fit against the cylinder.

Are there any pieces of cork glued inside the cowl? if not you can cut some cork 'discs' from a wine cork and super glue them in.

Funny, was just thinking of that and wondering what the best material to use would be, thanks mate

Neither, it's a noise I can hear at various throttle settings and engine speeds until engine rpm exceeds 5000 (estimated) rpm. i.e. engine is revving quite high. Also engine starts well, idles evenly and performance does not appear affected at any engine speed.

Impossible to diagnose by message really, more likely a rattle from what you've said but not defo. Best solution is to put it on a dyno run by someone who has got a clue. If it's pinking they'll prob be able to sort it (unless its derived from an air leak) or if its simply a rattle you'll be able to walk around the running bike and pinpoint where its coming from.

Try Readspeed, Taffspeed or Diablo Moto.Well worth the money just for peace of mind.
