Sitting around won't cause any build up of sludge.
Back to the boots.... I bought my K1200RS in November one year, and took it out a couple of times ... hadn't been on a bike in years so didn't wan't to start using it in the Scottish winter. Test runs were fine but gear change a little stiff compared to my last bike (Honda).
Took it out for a third and supposedly longer run... well I'd got new leathers and boots, so why not.... 1st 2nd 1st 2nd and NO 3rd (or 4th etc)
Tried it on centre stand .. worked fine
Tried it on th e road
parked it up for the winter after a couple of more attempts..
Come early Spring I had finally twigged that on the first two runs I had ordinary shoes on.. took the bike out again with shoes on , gears were fine (well, notchy, but all there).
Discovered that the pegs and levers were in the lower position and the gear lever had a 1.5" lower extension which meant the angle, with boots that prevented ankle pivot, was such that lifting the lever didn't pivot.
The gear lever geometry is the worst bit of engineering on an otherwise excellent bike.
Removing the extension, changing the oil and putting in greased lightning means my gearchange is acceptable with boots on and excellent with shoes or ankle boots (or racing boots).
The gear box should be run in by about 25-30,000 miles and after that there should be very little to accumulate and contaminate the oil compared to running in. Should be a magnetic collector on the drain, but as long as the oil is clean and changed regularly you should have no problems with laying up the bike for months at a time..
Similarly the engine oil will be fine if it is clean and changed regularly, and after maybe 20,000 miles or so I would recommend fully synthetic oil. Bear in mind that because the gearbox is separate from the engine, and the clutch is dry, you should be OK with synthetic oil graded for cars rather than the horrendously expensive bike grade oil (In My Opinion...and thats what I use..).
