I just picked my first KDX yesterday, a very nice looking 1980 KDX 175. Some of you may have seen it on **** last week, I ended up driving about 5 hours one way to pick it up so I was releived to see that it is in as good shape as the pics look. It also came with 2 shop manuals and the original title! I just need to get a few basics for it and it will be ready to go. It runs great but I plan on getting new tires and chain before I ride it too much. This is my first 2 stroke since my Tri Moto 125 when I was about 12. The guy I bought it off was mixing it 20-1 but that seems a little much, I read in some of the fourms that 32-1 will be fine, does everybody agree? I am not sure when the top end was done last but it has plenty of compression and starts right up so I am going to leave it alone for now. It feels great to be back on 2 wheels again after riding quads for years!
