A few front end problems

Hello again,
Picked the wife up from work on the Silverwing last night and she is very impressed, she likes the sound of the engine and was very comfortable.
The problem that is getting on my nerves is a constant clonk from the front wheel, not a serious clonk just a regular clonk as the wheel goes round.
It sounds like something is knocking the front mud guard. I have had a look today and can not find anything. If you lift the wheel off the ground you can't hear it. while I was looking. I noticed some fluid on the brake calliper, when I checked that I found that it is shock oil, so I would assume that that is the seal that needs replacing. I also noticed that the brake pads are quite low.
Does anyone have any idea what the knocking could be and how long in labour
time would the seal be? I will try and have the brakes done at the same.
Thank you, Jeff  

Not sure what the DONK is - but from what you described I suggest you (you or dealer) check it out and make any necessary repairs before riding it any more. I would not ride a SWing in condition described until I got it repaired. Let us know more about the DONK! And, good luck.

Describing the noise as a Clonk, or as Dimond calls it, a Donk, is funny. I have no idea what a Clonk or Donk sounds like.
Doing the seals (you need to do both at the same time, otherwise be prepared to do the whole job again if you only do the leaking one) is fairly time consuming. I'd say at least 2 hours in labour at a shop. They might tell you that the whole front end tupperware has to come off. Not true. You can remove both front forks without removing the front end plastic.

Thank you both, the clonk or Donk is more like a plasticky sound, just like tapping the mud guard with the back of your finger. I know a chap who is a good motorcycle mechanic and cheap, so I will get the things done with him.

Next time you go for a ride gently apply the front brake (right lever only) with out changing speed and see if this makes a difference. Disk brakes are susceptible to picking up dirt,small stones etc. If this changes things there might be some foreign object on one of the front brake pads.

Thank you, NWSSC,
It could be something to do with the front brakes, although they stop fine.
There is not a great deal of pad left on them so maybe they are rattling on the disc as it turns.
I think I will do the pads first and see if that helps, then later on I will book the S/wing in,to get the fork seals done. Other than that I am very happy with the bike.
