Husaberg project

It seemed a good idea at the time - I've just bought a 94 Husaberg 350 as a project, thats it spread over the garage floor. First job was to strip it down, check the frame for cracks and get it powder coated. Sure enough there are a number of cracks, tho' nothing major and it will be an easy weld job. I'm pretty worried about the motor, there was no coolant in the radiator and I know it has been run just before I got it.
Dave Clarke Racing seems to have plenty of parts for this model but I can't find much info. Any pointers as to where I can find specs, details etc would be great.
