FINALLY found/purchased my WR-200. Factory manual indicates that compression is adjustable. Bottom of USD forks have plugs w/ recessed hex heads, but no "Clickers" to be turned. Are they under the plugs, or is it possible that some were turned out that WEREN'T adjustable, other than spring rate/oil level? Secondly, Yamaha manual gives this as compression adjustment. RaceTech says in their set-up recommendations that it's rebound-adjustable, but not compression-adjustable. 1st bike that doesn't have conventional:think forks. Which is it?

Under the rubber plugs are the compression adjusters. No rebound adjustment on them. You can change the rebound by using heavier or lighter oil but it then impacts on the compression side. If its way out a revalve is the way to go. They were a great bike in their day:)

TB,
That was cool bike.. I saw very few but one of the things that i thought was wild was the use of a bladder in the Yamaha made Ohlins copy shock..

should have indicated this earlier. There were/are NO RUBBER plugs in the recessed hex-head-shaped holes. This is why I was wondering if it were possible that manufacturer design changes at a later stage eliminated adjustable compression.
Actually what impressed me was the smoothness of the power delivery (broad power band for a 2-stroke) I'm not so hot on loose traction situations and even worse in the mud, if that's possible, and for what it would have cost to change the power curve on an MXer, it was worth the time/effort to find the WR Thanx Jeremy:confused:

TB There should be a slotted brass small screw head up in the hex head holes. Aussie WR200's all had the same style fork on them from late 91 through to the last of them sold in 1999. Great bike. Friend raced them and was very sucessful after adding a pipe and muffler. They have a very smooth power delivery even when fitted with a pipe. Watch the aircleaner. Its tiny and orig ones were pretty poor. Try aftermarket one and clean it often

Thanx ACS. I'll give her another glance in the a.m. Previous owner has a ProCircuit pipe and 304 silencer on it already, and after-market reeds (unk. make/type) Thinking of going to FMF Gnarly w/FMF Ram valve. If you have any knowledge of either, input would be appreciated. If not, thanks again for your help on suspension woes ;)

The Procircuit pipe and 304 were the hot item back then. I'm not sure about the FMF but we used a SPES pipe with a FMF muffler and the bike always went better than the others. Main problem we had was jetting the stock carb. Its a weird one that was near impossible to get jets (needles) for here in Australia. With the pipe open muffler make sure that the carb has much bigger main jet than stock and it needs a richer needle. A lot of guys bolted on the pipe and muffler and went up one size and normally seized them. We went from a 190 main I think to a 280. For the needle I had one machined up from a stock one that was richer across the range. Remember I'm talking about a Australian version so your stock settings may be different. Aussie ones were heavily restricted and super quiet and was road registerable at one stage. I looked for my work sheets on the 200 but I'm sure they went with the bike when it was sold. Good luck. It could be worth while posting in the YZ/RM forum for more info as the 200 was sold pretty broadly across the world and others might have more info

Thanx to both of you (ACS and KTM ) Will try question @ YZ board and see what pops up. Knew I would get into this difficulty buying a 10 yr old machine. Got Hi-Torque Archives test article on the bike, and they seemed to like it, but did not have any aftermarket GOODIES hooked up. Test/report was on the stock bike, pipe, spark arrester and All.
