I had a similar noise start on a Yamaha I run, horrendous engine tapping noise, its done 99K miles so thought its knackered, turned out to be a split leaking header exhaust. Worth a check!

Will do thanks

Sound like clutch rattle? Does it reduce/disappear if the clutch lever is pulled in?

[yozzer74]

Nope it stays there when clutch pulled in

The speed of the tapping sounds top end y.

It has got oil to both sides of the head? Hasn't it?

Take the tappet covers off to have a good look and don't run it if at all suspect.

Out of balance carbs. can cause rattles.

[yozzer74]

K2 that was first thing we checked .yeah plenty of oil .will take a look at carbs .

Hi Yozzer, as above I had that noise on mine and it was a leaking exhaust copper crush gasket, sounded very metallic, great relief when I check tightened the headers and it went away!

[yozzer74]

Cheers mark will give it a check

That's how the problem with my down pipe header is presenting itself.

[Greebo]

Sounds like loose tappets to me, if not possibly cam chain

[MarkCR750]

Have you found out what it was/is yet Yozzer?

[yozzer74]

Not yet mark it's my mates bike and he's away at minute
