The K13 handles low rpm's like a charm and I do not have to manage low speeds with a slipping clutch, hence the clutch does not squeal.
Does this make any sense ?
From my knowledge of the CA CHP patrol bikes, in 1997 when they began using them, they were smoking the clutches into a glaze from slipping them. Something they learned to do and it carried over from their Kawasaki days. They had to re-learn "Not to slip the clutch."
Maybe it applies to the squealing ones out their now? Someone riding and slipping them and glazing them up?
Of course the R1xxxRT-P are dry clutches, but they still managed to bugger the first ones up in 600 miles or less by slipping them.
You could be onto something as the original K1200 were a fit to ride in slow traffic with the airbox idle-control circuit fighting any resemblance of a normal and smooth idle. Wouldn't surprise me in the least if the clutches are glazed as a result. What BMW did was enlarge some oil port in an attempt to cool the plates and allow a bit more slippage.
Of course on the new 1300's, that will never happen since they cannot start at times, or just stall out where subsequent use of the clutch is pretty much useless.
