....dush! ...got as far as removing the engine cover and then realised the long alan keys were at work....so couldn't remove the air filter cover.
I did try turning the ignition to position 2 with the bonnet up and the UBP sounds smooth and sweet so it will make a reasonable emergency spare when I swap it out. Just have to remember to carry the tools I need to do the business along with the old pump.....that's where a space saver spare wheel comes into its own.
...ouch! bad accident at the end of GP2....at least I haven't been centre punched by a 600cc bike..I hope his luck quickly improves.
