Nice bike. Had one myself a few years back. It was a great bush bike.
Nice to hear from someone who had one. You got any pics of it or useful info that i might need? A seat cover is one thing im thinking about at the mo. Will probably end up taking it to an upholsterer and paying the price. Nev used a good one i think.
to look at yes engine wise no dt200r 3et 33bhp dt200wr 3xp 33bhp the 3xp has a longer 1st gear 2mm bigger carb 2 extra ports a nikel plated barrel and a diffrent right hand engine cover with no oil pump and is only a little bit quicker off the mark than the 3et
All the DT200R's and DT200WR's in the exploded parts lists have an oil pump showing. the first ever DT200 to come out of production, was in 1988 as a DT200R, this was the 2YY1 model, and was made for the French market, and the later 2YY1, again a DT200R, produced in 1989 for the European market, the DT200R 3ET1 was also made in 1988 but for the Japanese market. The first DT200WR was the 3XP1 produced in 1991 for the Japanese market, as was the (3XP3,1992), (3XP4 1993),ending with the 3XP5 in 1994. not showing the difference in barrels regards to nicosil plating but the DT200WR 3XP head and barrels all had the same 3XP-11311-00 head and barrels, whereas the 3ET1 and the 2YY1 both shared the same 3ET-11311-00 barrel, but for some reason differed with the heads as the 2YY1 DT200R used a 3CJ-11111-00 head, and the 3ET DT200R used 2 types of heads the 3ET-11111-01, and the 3ET-11111-00.
Oh aye the carbs, the 3XP Carb may have been bigger, but is totally different to the 3ET Carb, the 3ET looks like a flat slide Mikuni, whereas the 3XP Carb looked like the half flat slide half round bit like the Dellorto/Keihin ones

No worries I'll tell you what I know. It's a great bike. A real step up from the DT200R; especially the suspension. If you get it going well I gaurantee you will not be dissapointed compared with a DT125R or DT200R in the bush (hope that's not sacrilige to say that here!). Once you get them sorted they are very close to a match for the modern 200 cc 2 bangers. The bike was sold in Australia as the WR200R, premix only. I've seen bikes overseas variously named WR200R or DT200WR. Photos of the DT200WR normally seem to show bikes that have oil injection and DT stickers while the WR seems to be premix with WR stickers but there appears to be some exceptions (possibly engine swaps?). It may be that the DT200WR has the DT engine and the WR frame and suspension. They also sold them somewhere with red plastics and black frame / seat which really looks the goods.
Plastics and tanks are unavailable off the shelf aftermarket. Yamaha may do them but to give you an idea last time I looked for a pair of fork sliders they were obselete. Most other parts (including seat covers, engine rebuild kits, brake overhaul kits, bearings, seals etc are all available freely new of EBay; especially EBay US. I think there is a set of brand new white radiator guards on US EBay right now.
Your bike looks like a premix model. It is missing a plate that goes over the oil injector pump housing on the right hand side of the engine. The engine is basically a DT200R motor and most parts are interchangeable. The main difference is the DT200R has a cast iron liner in the barrel and the WR200R barrel is Nikosil plated. There may be some differences in porting, ignition timing and power valve timing, not really certain but the CDI and voltage regulators are different as you have found out. As far as I am aware the WR stands for wide ratio but more in the sense that the bike was marketed as a road legal motorcrosser with wide ratio gear box to compete with the KTM of the day and the Suzuki RMX250 which was selling in bucketloads (even better bike). I suspect the WR and DT200R gear ratios would be very similar if not the same. The WR also does have a larger more tunable pumper carbie than the DT and different airbox. The real gem from that era is the YZ250WR which is a true road legal 2 stroke motocross bike with wide ratio box. If you ever see one of them grab it.
The suspension on mine was done by the guy who previously had it but I suspect they are basic dampening rod forks. If so they can be well sorted with progressive springs and/or a Racetech catridge emulator. If they are more modern forks than that even better. The shock is far superior to the, let's be honest, journeyman DT200R one. There is a handy link for rebuilding the rear shock below.
Stock the engine is very quiet and smooth just like the DT but it is easy to get it going. Firstly Boysen do a full power block for it. That with a good exhaust really gets it going. As well as your pipe, you can get FMF pipes, Pro Skill (at least a DT200 one which could be easily modified with a bit of heat) and Pro Ciruit used to do one. The Pro Circuit platimum series expansion chamber and 304 silencer is the pick for power. They come up on Ebay occasionally. If you do get one make sure they include the flange that bolts over the exhaust port. A lot of guys in Aus used to take the snorkle out of the airbox and drill holes (you can get plugs with foam from Ballards in Aus to insert into the holes). It made the bike a bit more powerfull, a lot louder and more finicky to jet. I had the snorkle out of mine for a while and ended up putting in back in. The last thing you can do before resorting to machining with both the DT200R and WR200R is remove the drive gear to the balancer. You need to remove the clutch cover and clutch assembly to get at it. The bike will vibrate a lot more but it really makes a huge difference to the throttle response and if you use it for the bush or track you'll hardly notice. I did it to mine and the thought of putting it back in never even crossed my mind - it hauled arse!
One last thing, maybe you guys can help me with this but I have heard that Maddog Engineering in the US do a 240 kit for both the DT200R and WR200. I have heard that the piston in the DT200R and DT230 are the same ?? If so, I'm assuming this kit might be based on a DT230 crank??
I'm also sure that the DT200WR all had the same carb shape as the one one the right, seeing as I have all the exploded diagrams here in front of me, basically if it was a DT200WR it was a 3XP, whether or not it was 3XP1, 3XP3, 3XP4, or 3XP5, any other bike was just classed as a DT200R, models for the DT200R were the 3ET1 and 2YY1. Carburetter wise like I say they all had the same shape carb, but part code they differed as the 3XP1 was 3XP-14101-01-00, and the 3XP3,4,5 was 3XP-14101-10-00, now whether or not that was size difference or not I don't know.
The WR200 made only 4 models the WR200RD 4BF1,1992, made for North America, the WR200RE 4BF2 1993 again made for North America, the WR200 4BF3 1994, made for Europe, and the WR200RG 4BF4 1995, again made for Europe, all these had the same shape carb as the DT200WR 3XP carb, but with the model code 4BF-14101-00-00
Interesting. I'm sure DeeTee's DT200WR had a tm28ss on and mine also came with a tm28ss carb on it as well. I wonder if the inlets are the same size as the 125 then as mine has no stub for the oil and some definitly ran pre mix where as others werent fitted. I'm going to be setting up the oil pump and so will need to fit a dtr inlet with the stub.
What site is it your getting all the explodeds from nev?
The WR carbie doesn't have the coolant routed through it from the head like a DT200R either from memory. You'll also need to change the throttle cable as you probably know because the DT200R cable splits into two - one to the carbie, the other to the injector pump. I'm assuming a DT200WR (with oil injector) would be set up in a similar way. I reckon a DT200R reed block with the oil inlet in the front would most likely fit as well.
Right, so its not the same carb as is in the picture on the right, the Mikuni TM SS which is the given carb for both 3XP's and the 230 Lanzas then, but the same as the Mikuni Flat Slide on the left picture, albeit much bigger as it's a 34mm. It's just that I've found a Jap website for setting up the carb, just need to establish the original size on the bike.

From looking up about this lanza carb all I could find at first was the dt200 runs the same tm28 as the 125 I was going yo try the 28 on this 230 but desided not to lol
the one on the right is a d slid if im correct thats what should of been on the lanza and the wr200 but rare as **** lmao so i just got a normall flat side the dt 200 should be running a up jetted tm 28
Well the carb that i got and thought was a TM30SS appears not to be. This is the D slide carb that apparenetly came from a YZ125. Has the plunger style choke as opposed to the lever and the internals look quite different.
Right then I reckon I've sussed it now, the MIKUNI TM28 SS was fitted on the DT200R (3ET1, 2YY1 models)as the parts picture on the left of the two carbs earlier show, the TM 28 SS was a normal 'Flat slide'.
The DT200WR (all 3XP models) and the DT 230 LANZA (all 4 4TP models) had the Mikuni TMX or TMS series carb, all having the 'D' slide
Thats sounds about right to me. Yeah thats the breakdown parts list i found nev. Matches up to the one i have here.
This one wasnt from a WR200 or DT200WR though, it was from a YZ125 1989 model. I just bought it cos i thought it was a tm30ss which was what was used on the DT200WR / WR200.
I guess someone has seen the DT200R has the tm28ss and bought one thinking the wr used the same.
I'm gonna use one of my 32mm dellortos for mine i think. Probably sell this TMX35.
Well I'd say all depends on if you've had the barrel ported etc. If you have everything else just standard then not much more than standard. I'm gonna put a 32mm dellorto on my DT200WR but thats ported differently to the dt200r. I'd probably try something like that though, maybe a tm30ss but you'll never find one.
