Hi, I've just signed up and would like to introduce myself... if anyone cares I've been riding bikes since the mid 70's ( started on a Puch VZ50 if anyone remembers them.. ) various BSAs, Triumphs, an amazing RD400, Moto Morini 3 1/2, Dneiper, XS750, KLR250 amongst others, and more recently BMW F650GS. And now I'm also the proud owner of an '81 DT175MX. I live in Bulgaria and love touring and riding trails which we have pretty much free access to here,(hence the DT as the BMW is just too heavy and I'm embarrassed to be overtaken by teeneagers on their dirt bikes). My Mrs and I also happen to run a bike friendly backpacker hostel in case anyone needs a bed or a garage and help in Bulgaria. I'm no mechanic but I'm not totally ignorant either.... not soliciting business but we love it when real travellers call in, even if only for a cuppa. We're kind of on the way to/from Greece and Turkey. Anyway, enough of me. I have a few questions re my new purchase ( ebay from Germany, 650 euros ) It's a 2k4 (1981) and is different from the UK models in some minor aspects (eg wiring), basically in vgc but needs a good service. My manual says 10/30 engine oil for the gearbox. Can I use any old oil or will I end up with clutch slip? Your recommendations please. A local friend suggests ATF for the forks.. any comments? Incidently, the German log book has the cc as 169cc which I really don't understand. Does anyone know anything about this? I look forward to hearing from anyone who has nothing better to do... Thanks, Nick.
