Check those links, there's some cool stuff on GPZ (EX) 500 racebikes.
Domènec says... Many thanks, that's given me a few ideas. I really like the Airtech seat unit in the first link. I'm quite lucky to have a European 'E' model with twin front discs, so my braking will be miles better than a normal GPZ. I've already prepared a set of clocks in a new housing, minus speedo with the glass blacked out altogether. I think I'll be able to save about 15 kilos in weight by junking unneeded road gear, the headlight alone weighs about 3 kilos. Just got to make some rearsets now and a few little bits like clip-on brackets and an exhaust link pipe to take a Micron carbon end can I have spare. You'll find me in the workshop if you need me.

It is easy to try and easy to recover if it doesn't help (just use some of the spare tupperware plastic ;-) unit in the first link. Er, you *didn't* know the Airtech site? www.airtech-streamlining.com BTW, check the Yamaha YZF '92 fairing, that could be my trackdays' fairing for the 'ace. a set of clocks in a new housing, minus speedo with the glass blacked out altogether. I think I'll be able to save about 15 kilos in weight by junking unneeded road gear, the headlight alone weighs about 3 kilos. Notice that the Brazilian exahusts save themselves more than 3 kilos. Another way to save weight: - Start engine, but requires something to start the bike, a-la-motoGP. I'd keep it, when you get out of the track and the bike stops, it helps getting on the track again and not waiting for someone to pull you back to the pits. - Battery and "alternador" (English?) Use a mopped battery, much lighter. There are also "alternador"s for racebikes which produce strictly the current required by the engine (no lights, etc) and are lighter (in weight and brackets and an exhaust link pipe to take a Micron carbon end can I have spare. You'll find me in the workshop if you need me. Pictures and work reports will be welcome. My GPZ "B" now is just a frame with the engine... and feels like rather than using it for GPZ "A" spares I'll try to get it running. Nice to see the price of used bike parts in eBay and how they can fit in a "on-demand" 500 racebike (yes, a used CBR is cheaper and faster, but what the hell, not as much as funny
Domènec says... That's a good tip that I may take advantage of. I know of Air-Tech from my days owning Yamaha RDs, they make some really nice bodywork for those. They are very expensive though, and shipping glass fibre fairings and panels to the UK might not be successful. Nice. I think using a 2-1 exhaust system will save me alot more than 3kg. My micron can weighs half that of a standard unit, and I'll only have one of them. I'd like to keep all the standard electrical ancilleries. I'll keep you updated with progress
