First week of January i'll be taking it in for a poke-about.
Will be:
- Checking plugs
- Checking choke/s
- Replacing air filter with a K&N
- Replacing oil and filter
- Checking state of carbs/clean
- Balancing said carbs
- Checking 02 levels.
Treat yourself for Xmas and add a fuel filter to that list for an extra few quid. 
I presume your calipers are okay and not sticking/binding as well, 'cos that certainly wouldn't help matters?
Ahh yes. I shall add that.
Callipers are good. I serviced them Very recently (less than a month ago).
