A buddy of mine bought this RD200 a year or so ago, and never got around to doing anything with it (needs some assembly). He doesn't want to mess with it...so now it's mine! Future Lake Erie Loop contender right here, folks. Should be fun.
On a side note, does anyone know what lubricant should be in the crankcase on these?
10/40
Um, this a 2 stroke, the crank is lubed by pre-mix oil in the fuel, or this one may have an oil injection system, my RD 350 and 400 did. I used casterol out-board motor 2 cycle lube in the injection system on both of mine with no problems, YMMV. The gear box and clutch probably use 10w40.

I'm aware of the oil injection system, or "autolube" as the FSM describes it. The cylinders draw from the side cover reservoir; there's a dipstick in the crankcase that I assume is for gearbox lubrication, but may be shared. The FSM is really vague so I figured I'd ask here. So 10w40 is golden for the crankcase/gearbox?
10w30 or 40 is fine for the gearbox. it is not shared with the crankcase. make sure your injection oil is for air cooled engines, as its designed to burn at the higher temps that air cooled engines run at.
On my rd250 and 350 I run Yamalube in the oil injection system and phillips 20-50 aviation grade straight mineral oil in the gear box. Stay away from friction modifiers in the gear box.
That thing is cool!
I might have to check out this Erie Loop event. I don't think I'm up for the haul, but I've got the bike...
Thanks for posting your score!

Progress being made on the bike. The fuel petcock was jam-packed with dead beetle carcasses - EWWWWW! Fuel actually flows again. I've tightened up all the bolts and gone through the wiring, seems OK, I primed the oil pump and tried to start it yesterday but I'm only getting spark in one cylinder. I forgot how much I hate points, going through those tonight after work.
Since the stock airbox is missing (filters are NLA anyway) and the stock exhausts are totally knackered, I'm going to have to jet the carbs on this thing by trial and error. It should be a screamer when it's done, but man, what a pain in the ass!

Nor anything as sweet smelling

Cool little bike!
