Info on 91 KDX250SR

[RFJ_His_Son]

Hi all,
I just bought a 91 KDX250SR, and am looking for any info on servicing/tuning/accessories/suppliers for this bike. Took it offroad straight from the store, great fun, but awful tyres, so tyres, renthals and barkbusters getting fitted at the weekend.
Questions
what is the capacity of the autolube thing?
what is the fuel tank capacity?
anyone else trailride around Mansfield Notts?

thanks in advance
