Hi Fredswat,

Fantastic job you're doing there and the paint job looks ace... 8) 8) 8) 8)
I spotted the back end of a Z1 in one photo, do you have a photo of that to share too?

Here is a picture of the Z1 (Attachment Link)

Cheers, I like that, twin front discs too, genuine UK bike that must be then? Yam strokers and big aircooled Kwacks are the best of best worlds..... 8)

Yes it is a UK bike bought a while back when they were cheap

The ones you have look good and if you'd got RD200 ones from USA they'd have more than likely been the wide'high 337 bars. Nice bars but prob need longer cables for them
There is a great review on the RD200A at
https://www.cyclechaos.com/wiki/Yamaha_RD200/reviews
The guy quotes
The little bike exhibits all the stability and handling talents of a born racer which, strangely enough, it never was originally, unlike the bigger Yamaha strokers, but the 200 has always tended to lurch around a bit, something which has always been simple to resolve by either enjoying the impression it created of real racer skill and bravery in the minds of even the least imaginative riders, or to remove the touring type big handlebar latterly fitted by Yamaha, and replace it with a short, flat one.

This exercise shifted the rider's weight forward and therefore increased his damping effect on the front tyre; simultaneously the shorter handlebar reduced the effect of his reaction to wheel wobble on the wheel itself besides reducing its effect through the bar to him and thus ensured a more stable ride.

Great when I was teenager and only weighed 10st 8lbs but now with the beer pot and stiff joints, I'll still keep the low UK bars  :o. Plus the UK has the steering damper which I loved on windy day driving over the old Severn bridge.

Bit more RD200 progress after a long gap .  Got a replacement seat base in good condition .  Had it powder coated.  I had a go at fitting a new cover.  Not the best results .  I think I will do it again at some point.  Switching to engine reassembly next

Hi Fredswat
On the RD200A.
I looked at similar rear shocks to yours but found the the LH one fouled the chainguard. Have you bounced the rear end yet to check it clears

Bit more progress on the RD200 - Fitted new outer crank bearings and Gearbox bearings.  Getting ready to refit the crank. Some photos thus far.  I am a bit nervous about assembling the engine, it's been a few years since the last one (Kawasaki H1) and that was horizontally split.  Did an Aprilia rs125 a good while ago which was split vertically but it was a single so seemed a lot easier.  I'm sure I will be ok.  It's been a good while since I took the RD200 engine apart so hopefully I remember where it all goes.   * progress aug19 1.jpg (669.31 kB. 1512x2016 - viewed 19 times.)

Hi Fredswat   8)
Looking good.
Did you have the crank rebuilt. I've got a engine for my USA RD200C that was seized (missing its pistons) that I got turning over with telescopic magnet, penetrating fluid and lots of rocking crank. So this will need rebuilding. I have a spare crank but the tolerances are at extreme so would also need rebuild.
If you did, can you pass on their details please.
Thanks
-Mike
