Fitted the Safari tank to my FE450 between Xmas and New Years. Not quite straight forward, but that was more due to the fact I am running B&B Offroad radiator guards and case saver. Had to file some off the bottom of the louvres on the radiator guards and I added another layer of fuel hose as added protection when I ran the fuel line around the outside of the case saver.
Will be going for a big ride on Monday to try out the new rig. Will get back to you to let you know how it all works out.
If you succeed at first...don't look surprised!!
More enthusiasm than ability!!
