Fitted a 1/4 Action throttle from a 1988 KX80. The throttle tube is a larger diameter, much more comfortable and has been invaluable as an upgrade. I had to modify my 'Genuine' throttle cable by cutting back a bit of outer sheath. XT600 brake lever is a great swap, and I use a little shorty alloy clutch lever of a 85cc on there.

Needed to replace the original headlight cluster.

Missed out on a decent Yamaha WR400 headlight.(Perfect shape) Got one of a Aprilia RX, had to do some wiring for this. Needed to be painted white of course. Its worse than the DT headlight.. but, got the look.

If your into DTRs. Then the DT200R (3ET) is the one to have. I couldn't find much information on these (YZ) wheel upgrades I've seen. I wanted alloy wheels on it like the 200. So after some research and a failed attempt at getting a set of WR200 wheels, I concluded that 1988-94 Yamaha YZ wheels have the same size rear hub as the DT. Straight swap. For the front, had to be 1987'-1988' because they ran similar sized rotors back then. However the hubs are about 10mm wider on the YZ, So I chose some YZ 1986' front spacers, looked similar proportion to match a DT fork in the pictures. If your going to swap to a YZ wheel, I gave up trying to fit the Speedo drive back on and took it off. Took of the clocks. Then fitted a bicycle wired speedo, just for an MOT really.. its crap and does not register the pick up past 60 mph or so. Minor price to pay. A vapour unit out of the budget. Don't need idiot lights for wheelies.

Yamaha built the 1986-1988 YZs with Gold anodised rims and man.. wish I could find a back one. The front is a 1988- the back of a 1994. MX was starting to use 19" rear wheels for better drive and handling back in the early 90s. Yamaha were on this on the YZ range. Bigger wheel does throw the gearing off slightly on acceleration. Got a big dutty knobbly on the back and you really loose out on power if you have to nip along the road.

The rear shock is crap on any DTR, or at least mine was. Did some googling' and a man in Australia agreed with me, and I had to copy his idea for myself. The DT uses the same shock to linkage fixing as 87-88' YZs Shipped a 1987' Yamaha YZ490 Rear shocker that bolts right in! Its even got Yamaha's 'B.A.S.S' system on it. Which is rubbish.. but cool anyway. When fitting it, the top damper mount on a YZ frame is different, apparently much narrower than the DT frame, so you will need to use the bearing with it's fixed spacer off the DT shock and replace the YZ one with it. I actually used two big cable ties instead just to stop any lateral movement under compression. Anyway I now have Adjustable spring rate, Damping settings and Rebound settings. It will sit pretty high on a firm setting. 4-5cm lift. I also stuck with my short Dog-bones,3cm riser ones. It gives the shock better clearance from the swing arm, its a tight fit.

I cannot find the thread any more, but here are the pictures on the suspension modifications

I already replaced the battery with a capacitor from '2strokeracelab' - check it out. The shock is bigger than the DT unit, longer and a fatter spring with of course,with a piggyback reservoir. So there is no room for the battery. It is also no going back as there is the tab which the battery tray is bolted to on the frame, which has to be cut off for the shock to be accepted properly. I also cut the side cover apart. Bit easier to get a flat head in for adjustment and gives me access to the Yamy Tool kit.

I use 15w Fork oil and it makes the best of the standard forks. I do own a very nice set of 1991' WR200 Kayaba Forks. I chose them because the WR yoke had an Ignition mount. They are just the right forks for it. But I don't want to modify the frame to accept the WR stem. I'm looking at having the Stem pressed from the WR yoke, and getting it machined down with an extended thread which would allow me to just use the original top cap and ball bearing race on the DT. Need to model it in 3D first.

I'm at University currently so I just stock pile things at the moment. But future updates; Installing a Twin radiator configuration from the DT200R(3ET) - Got all the goodies now. I've also got a 'Ignitech DCCDPI2' on the way. The 3RM' really needs ignition modification before anything else. And the fiendishly unfriendly, how do I horse anything bigger than a 30mm Carburettor? plans to Original Air box configuration at some point,

It does not need to be big, I have drilled out the Air box already with good results with some Jetting and Pipecross Airfilter fitted. But I do have a Keihin PWK 36 that would be alot of fun.

Picked up a very nice Yamaha TZR125RR (3MB00-P-Y2) Barrel ages ago. (The real deal Y3 Belgarda' has eluded me) Just a display piece at the moment. Interested to hear about any Porting experiences.

Thanks
