One Mans Junk.... '72 CS5E (RD200) Build.
- Thread starter Jim
- Start date
My first bike was a '74 Kawasaki S-1 250, I remember that feeling well!Yeah, more so the pre-reed valve engines. The reeds spread the power band out and lowered it. Made it "feel" faster.
Pre-reeds it'll act dead 'till comes up on the pipes. If you've never ridden an old narrow band two stroke, you'll be in for a treat.

That's the funny part Bob, of all the RD's Yamaha made.... 80, 125, 200, 250, 350, 400....Yeah….plus it’d be a hell of a lot easier to kick start that that BSA Victor of yours!
Of all of 'em, the little 200 was the only one that was standard with an electric start.
Including the cush drive rubbers and sprocket carrier?
The shoes are the same for the RD200 and the XT500. So that might just work. What's the rim diameter Jack?
The good news is looks like you have the original brake backing plate so you can get an idea of the axle size.
LT2 yamaha may be a good match on some of the axle spacers etc. I have one of those also if you need measurements.

Same electric start as the 125 dirt bike. reversed the connection to the alternator to make it spin. Never worked on the one I used to ride .
What about the cush/sprocket adaptor?
Hey Jim. You better hurry! The 2022 Kansas City ALL 2-Stroke Rally is August 13th at Johnny Ray`s Drive in. See You There.
August 6th is the 10th anniversary Commemorative Air Force Plane & KCVJMC bike show at the New Century Air Center. If It`s under 200 degrees in the shade I`ll probably take the Last Tracker to that one.
September 10th is the VJMC show at Donnell`s Motorcycles. That one is always a good show.

Well, I made a few 350 sets a gazillion yrs ago. I reckon I got one more left in me...
I think there are some proven patterns on line.
If memory serves me correctly.

Thinkin' out loud..... @RustiePyles is a better welder than I've ever been or will ever be.... last I heard, he was needin' paint. I smell a trade.....
I'll bend 'em up and tack 'em... let the master do his magic.

Finding a rear wheel with all the spacers etc will be tough.
A swap comes down to axle width and diameter.
I suggested the LT2 wheel because it uses the old style 4 biskit damper and I think the center spacer #7 is the same as the rd suggesting the same axle diameter.

Not too concerned with spacers. I can scrounge or turn my own on the Atlas
Axle is .5865" (14.9mm)

Swingarm axle plates are a RCH over 8"
Making your own pipes for it should be easy . Copy the GYT kit pipe for the LT2/ Mx100
I'll go out to the barn in the morning and measure. I think the rim is toast but would make it easy to ship.
The ke100 carbs 26.2 inlet size

just shy of 15 on my plastic HF caliper in the dark and somewhere around 7and a bit inches.
Would at least make it a roll around project. You might have to scrounge a RD axle.
The only concerns are head and base gaskets, crankcase seals availability. I don't think I would go into the bottom end . If there problems there done deal. otherwise clean up the bores and see if it will run. It sure would wake up the neighborhood.
The RD200 dates back to the dawn of time. The first bikes of this design was introduced in 67. The 75 RD200B was the end of the line.

I've got the axle. Let me know what you want for. PM on the way.
