clunking noise on rough roads

[stroller]

I keep hearing a loud clunking noise when riding on rough road surfaces. I have a Motorrad concepts hugger and wondered if it was this knocking the swingarm, or could it be the suspension linkage? Nothing seems to be loose on the bike - anybody experienced the same thing?
Thanks,
Mike

Yep it's the hugger.

Is the hugger eating the sides of your rear tyre? They all do that Sir....

{Well probably not all of them and no offence to those nice chaps who were part of Motorrad Concepts before it went tits up. There are nice chaps who were part of Motorrad Concepts - there appears to have been only exception to the rule. However, I digress....}

If it is, yes it's probably clouting the swing arm at the same time. The cure is to remove the complete hugger, remove the alloy supporting arm from the hugger, attack the groove in the glassfibre hugger and the back of the support arm with a wire brush in an electric drill to remove the paint, a bit of the layer of gelcoat and any epoxy that remains on the support arm. Clean the alloy arm and the groove in the hugger with brake cleaner to degrease them and then expoxy them back together with Araldite before refitting the retaining screws. Then refit the hugger, checking the clearance to the tyre on both sides.

Or, when you remove the hugger you will see where it has been rubbing. Adhere a thin 'cushion' here (foam/rubber sheet whatever) and the clonking stops

After wasting a fair amount of time messing around trying to find the source of knocks and rattles, the first thing I do now is remove the panniers. 9 times out of 10 they are the source of the problem.

Noise

Get better ear plugs or buy an 1150.

Removed the hugger this evening - the tyre has been rubbing both sides and worn a grrove in the inside of the hugger, and there is a smooth patch on the hugger where it has rubbed the swingarm (no damage to the swingarm that I can see).
Funny though, the clunking sounded metallic rather than plastic hitting metal.

Cheers,
Mike
