1990 KDX200SR

Post by hi-def » 06:07 am Aug 26 2020

Hi all, kdxrider has been a good source of info for me so thought I'd sign up and show you my bike.

After having a KX125 years ago I knew I wanted another bright green two stroke.
Then I saw this one and had to grab it.

It's a Japanese market 1990 KDX200SR (G2), it runs ok and appears to be fairly original.

After cleaning it up I got on to what needed attention - mainly just a sticky throttle, weak brakes and leaking fuel tap, not too bad so far.
I even reinstated the road gear, speedo, signals, mirrors and headlight and thankfully it all worked even the ac flasher unit.

I knew I'd need to check the engine, especially the KIPS valves but only got as far as removing the lefthand cover when I found the first issue, lots of oily muck in the cover due to the almost non-existent crank seal.
So that is where I'm at, I have a full seal kit and will throw new bearings, rod, piston and rings in it and probably some new powervalves I imagine :grin:

Welcome to kdxrider.net!

Thanks for signing up and posting pics of a bike many of us have never seen. It looks good!

Check to see if the three indentations behind the stator plate are leaking.

Welcome and congrats on the new bike. We didn't get the SR in the states, so we are always happy to see one surface and see whats the same/different/unique, etc.

It's an interesting one for sure, USD forks, metal tank, oil injection, 28mm carb, no battery but all the lights, pillion footpegs...
They weren't sold here either but we have a big used import industry with vehicles from Japan so a few made it over, not many though.

Finding a matched pair of road legal tyres has been tricky, mostly with the 19" rear, there isn't much of a market here for them. Finally found the Michelin Trackers which seem to fit the bill.

I have the Japanese owners manual for the bike (in Japanese of course :) ) if anyone needs any info
