Hi, I recently purchased a 2006 GL1800 (40,000 km, 25,000 m) with a Motortrike kit. I am new to the GL1800 so am looking for some advice on flushing the rad (if necessary) and not sure when to change the differential oil in the trike and what kind to use. Also there is much contraversy on whether there is an inline fuel filter or a filter on the fuel pump on the GL1800.
Any help would be greatly appreciated.
