Hi Worzel and welcome to the forum. We have more members around Peterborough too so keep your eyes open.
If you go to the home page there is a very good section on what to do if you have just bought a K bike.
On the coolant, if it is travelling back from the expansion bottle to the cooling system as it cools the sealing may not be a problem. Make sure the expansion bottle is topped up to the max line when cold and that should be it. The radiator fill cap is under the petrol tank and the tank must be lifted a little and slid backwards to access it. At 1985 you should check your fuel pipes, preferably replace them as they are under pressure all the time due to the fuel injection system and they perish. When you go at the tank they are likely to crack and leak. BMW line is cheap, but if you put them back a bit longer you can slide the tank and also raise it without having to disconnect them. This means it is much easier to access the radiator cap if you need [its on the right as you sit on the bike] and the electric box [relays are all in it, its under the back of the tank]. My RT is 1984, your tank is probably held in place by a bolted plate at the rear of the tank, visible when you open the seat. If not then you have the later tank which is held in place by two poppers [like on the side panels] and clips which can be tricky to remove with the result that most leave them off.
There are wiring diagrams on the forum, you need to talk to Crazy Frog for access. Check out threads for the fuel gauge fitting too, others have been there before you.
Did you go for a Clymer manual?
When you get a bit more adventurous think about a trip over this way. Looks like we already have two takers for a trip to Northern Ireland in September. You have a nice route from Peterborough up to Holyhead and across to Dublin........especially if you take the straight line route across Wales...
