Tim,
To be honest mate, I don't think I'm riding anywhere near the full capabilities of the bike! There's a lad from somewhere up hear that I've seen on a couple of trackdays with a 748R and he's always the quickest thing out there. Gets reeled in on the straights by the bigger bikes but as soon as it's into the twisties he's off like a rat up a drainpipe. So, I really need to learn to get the most out of what I've got now before going for more power. Let's face it, where's the fun (or skill) in going fast in a straight line!?
With that in mind, the next stage is forks and shock off to K-Tech for some fettling.
As for brake light switch, I guess the easiest option is pressure switch in banjo bolt although I've just seen that Yoyodyne in the states are now doing a kit that lets you retain the OEM switch with the radial pumps. Don't know if anyone in the UK is doing the kit though.
