As has happened to many other folks, I've had problems with cooling on my K1300S, especially when in hot weather and slow riding in European towns with their 30kph speed limits - it's not long before the temp climbs and the fan kicks in - and when it gets that far I get quite nervous about it overheating.
My radiator is new (and yes, it was vacuum filled) coolant is the BMW stuff that must contain a fair amount of gold particles or something, given how much it costs. I don't think there's anything wrong with the bike, other than poor design. So I'm thinking about adding some extra cooling - a radiator would be tricky as there's nowhere to put one, but I think I can squeeze in a small additional oil cooler under the headlight somewhere. Has anyone tried this? And can any of you lot see any problems with doing this? I'm thinking it'll add some extra cooling capacity (not much, but I don't think it needs much extra capacity - a little bit extra should help, in any case), and it's still thermostatically controlled if I run the lines off the existing oil cooler.
Any thoughts before I waste approx £150 and a LOT of time?
Thanks!
