I've been working on one of my 800's:
Fitted Power Commander and uploaded a tweaked map - there's something really geeky about having a laptop hooked up to an old air-cooled 2vlv twin and seeing my neighbour's eyes out on stalks (he's a Max Power car freak with an Escort Cosworth - I've just outblinged him).
Fitted spoke alloy Marchesinis.
Fitted cast-iron fully-floating Brembos.
Fitted 4-pad calipers robbed off a 998.
Installed K&N filter with a cutaway air box
Fitted DP rearsets
Now I'm just waiting for my pipes and next week it's the Ohlins and refurbed fully-adjustable Showa forks with Ohlins springs.
