Assuming its a laterish version, 1lt of 10w40 engine oil, 85ml 10wt fork oil, DR8ESL plug, .002" on inlet and exhaust. If its ex aussie post the rear brake drum will be rooted from all the stop starts, and some uncaring riders would smash them through the gears causing a little crack in part of the selector mechanism, which is easily replaced under the clutch cover. Other things to look out for , the heat proof buffer under the exhaust guards get worn from vibrations an fall out causing the exhaust guard to rattle like crazy, and the rubber over the clutch adjuster on the clutch cover goes missing with regularity. Don't take off the chrome rear rack, as this forms part of the airbox and they run like shit without them.

cheers Bill, its the bike they had in the warehouse apparently so its well looked after. done bugger all work and very tidy for a postie. puppets never been near this one ;D

sil has put a pit bike muffler on it as the original had rusted away from sitting around. its a bit loud and pops and back fires on a closed throttle.

I dropped the needle clip and that improved it but its on the bottom clip, needs the next needle and that aint gunna happen im guessing. next will be to repack the muffler and attack from that end.

Postie bike fork oil, reminds me of a mate getting a roadworthy on his postie bike. Got knocked back for leaking fork seals but didn't want to spend a single dollar on this thing, mechanic said "go home and drain all the oil out and degrease it, can't leak if there is no oil in there", I rode it once, went through a gutter and almost snapped my wrists.

took her for a spin then drained the oil, pulled the front wheel..like absolute new in here, drained 1 fork by pulling the damper bolt out.

will get the other tomorrow  hoping its like the first 1...tap with the nylon hammer and undid by hand...so nice to work on an oldbike that's not rusted, seized, rooted and difficult to work on.
