drivetrain clunk

[Ish]

Hi

My bike has developed a light clunking noise when riding along. It seems to be coming from the front wheel/front sprocket area but it's hard to tell when riding along. The noise is like a light constant clunk-clunk-clunk noise!

The noise only occurs when I have the throttle open and the bike is on the road. If I let off the throttle and coast along there is no clunk.

I put the bike on the rear stand and 'rode' it but there is no noise so it only happens when the bike is on the actual road.

Any ideas on what it could be or what I should be looking for?

Thanks for the ideas.

I will take the front sprocket cover off and give the chain/sprockets a proper check.

wazza330, you just reminded me that the noise is worst as you come on the power with anything more than 1/3 throttle from low revs especially in the higher gears.

I had a new chain & sprockets fitted and the noise is gone
