Title: refilling coolant in bmw krt 100
Post by: pinhead on August 23, 2016, 06:27:25 PM
Is there anyway of avoiding having to take the fuel tank off to refill the coolant when it has been completely drained?  Owner's manual says the fuel tank has to come off.

Have somebody else take it off for you.

Sure! Ride it on over. I'll be ambulatory by 5am. Coffee at 6. You can reuse the coolant if it's only a year old. For the fuel, get one of these cheapos if you don't like the taste of gasohol and drain the fuel into a clean container. That will make the tank easier to lift. You may as well get used to the removal procedure because it helps when you're replacing cables or wiring food processors and other gadgets onto your bike.

The dirty little secret is that by pulling the clips and lifting the rear of the tank out of the rubber bushings slightly you can pull the tank back far enough to get at the coolant filler.  You don't even have to empty the tank or remove the fairings or seat.  The guys at Motorad who designed this were really clever.

Make sure you disconnect the tank electrical connector and cover the top of the tank with a towel to protect the paint.   Don't pull it back any further than necessary to prevent putting too much strain on the hose connections on the bottom of the tank.  When you get a chance it would be a good idea to replace the old lines with new ones that are 3-4 inches longer to allow more freedom to move.
