Should I adjust my valves, and or sync my throttle bodies?

Its winter time and I can't wait to ride. I've been thinking of adjusting my valves, and syncing my throttle bodies. I'm a little hesitant because I love how my bike runs, and I don't have any perceivable "surge". Should I mess with it? Would I be fixing something that isn't broken?

You can certainly set the valves - but the engine needs to be at a good running temp to do the sync - and the downside of possible condensation in the oil after it cools

Patine is a virtue

Can't see how anything could be hurt by checking the valve clearances. If it's quite and running well you may find they are OK. Well I take that back I almost shoved the timing mark cover inside my wife's engine last time but hopefully your are not as fat fingered and clumsy.
