The first two pics are the actual pictures off ebay, which were coupled with a really terrible description of the bike and truth be told the old girl was in a mighty sorry state.
This picture was taken at least two years later as it already shows Ms. Braaaaaap with the XT600 frontend and panniers. At about this time I did a lot of miles on a by then already very, very tired stock XT500 engine with an absolutely unknown amount of miles on the piston.
What you see here is a manual ignition advancer. Nifty piece of kit, rather hassle free if lubed regularly there's not much to go wrong, right? Well, don't cheat and only look at the first picture to spot the missing part...
The last thing on the list was a very, very stiff throttle. It turned out, that with the TM36 installed, you have to use the correct combination of holes on the throttle-butterfly or the closer will tighten up before the opener cable. Ultimately a DR600 throttle grip and new cables will solve this issue.
And... ain't she pretty? Well, yes that exhaust's gotta go rather sooner than later. As I have a way more elegant replacement waithing for its turn.
