Decided to service the master cylinder on the Kwaka - what an easy job it turned out to be
(I was dreading it). Circlip came straight out with the long-nosed pliers, rest of the gubbins just pulled out. The kit was great and, after a mega clean, I reassembled using brake fluid as a lubricant for the new seals. Shoved the spring on the end and in it went - bit of a wiggle to get the circlip back in!! In actual fact, the brake doesn't seem a great deal different from before, although I do think its firmer despite the usual long travel. From what I've read, the length of travel to full brakes varies with bike and manufacturer, but I reckon the Kwaka, as a tourer, doesn't need a gnat's wing of travel to lock the front wheel. Anyhow, I'm pleased it's done and I can forget about it for a while. I may need new caliper pistons next time around, but the old ones are serviceable for my purposes. *Bergs* found the tiny 'pin' hole and used a strand of electrical wire to make sure it was clear.
Next job is to get a decent day to get it hot, then do the carb balancing with my newly acquired gauges. Hoping the weather gets a bit more reasonable as it's very unsettled at present.
Finally, for our Aussie friends, my sons have decided to visit Oz in Feb/Mar next year. They're starting at my sister's in Perth, then to Sydney for week, then to Brisbane and the Gold Coast for a week before coming home (4 weeks in total). Any tips I can give them will be very gratefully received, i,e, places to avoid, places to visit, anything that'll save them money and/or hassle.
