I have an '84 KX500 in the shed if anyone wants a project. It's mostly all there including a new set of plastics from Nightmare Racing and a set of decals. It will probably run although it feels a little down on compression, the front wheel has a massive dent, the pipe is in a couple of peices and it has the wrong shock in it. It's a non reservoir shock which works well and could be used no problems, it's just not right for the model. The seat foam has been cut lower. The frame is a bit yuk, but there's a really good frame to go with the bike as well. It'll be a long time before I get to it, so if anyone wants it $2k, non negotiable. You should end up with a nice race ready bike for under $5K. I also have some other projects which can go if anyone is interested: 1981 KTM250GS, 1981 KTM390GS, 1974 Husky SC125, 1974 KX125, 1976 KTM125MC5, 1978 Montesa VB360, 1979 CR250R, 1976 CR250M2, 1974 Montesa VR250. There are also a couple which are half done but will be expensive: 1979 Honda CR250R (360 kitted) & 1977 Suzuki RM370 MotoX Fox replica. There's the other one as well Paul, if you're still interested.
Cheers,
K
