Hey Bruce , welcome from sunny Dartmoor .
Always good to see a fellow Brit here !
Great site this with great people .
The pitting on your forks are most likely stone chips , more often than not caused by keeping up with sports bikes , not to worry unless they start affecting the seals !
As for the plastic ? Take her for a good run , the hotter the exhausts get the more brittle the burnt plastic will become and you will be able to pick it off . Just don't be tempted to use anything abrasive !
Enjoy the buzz .
