Got the chain off - and very very stiff it is. The master link was really really tight , not due to rust but due to a bit of metal deformation on the pins. No idea how they managed that, or if it was just a really old chain.
Decided not to clean the chain, but get a new one.
So new RK 520 chain on the way.

Cleaned the back sprocket and started on the front sprocket area.
VERY gunged with old crud and oil and lube.

Sir Blue Henry · 11-27-2012, 10:50 PM

Still busy cleaning all the gunge from anywhere near the chain area. looking better.

IMHO you should replace the sprockets too. If the pins on the old chain are deformed, the sprockets are worn too. Spend the money now and avoid the headache.

Sir Blue Henry · 11-28-2012, 08:12 PM

well - i might have to do that, but just looking be eye, I must say they look pretty good, but then not sure how good my eye is hey.
I will put up pics

Being a cheap ass KLR kind of guy, I hang on to old sprockets and have been known to go through the pile and pick the best to stick on the bike to finish the season. Usually the season will be winter , because if springs on the way it's time for longer term solutions.
From the look of your sprockets, I'd put them on , even in the spring.

When your chains and sprokets are really done , weld them up for repurposeing.

New chain on. Tried again to start - no luck.
Checked the spark again and saw it was weak and not sparking correctly over the point.
New D8EA plug

test again - no spark
started checking wiring and then found one of the wires from the battery which has been soldered onto a small black component has come off.
and i have no idea what that small component is?

Sir Blue Henry · 12-02-2012, 10:08 AM

There you can see the little component just to the right of the battery - with the solder joint on 1 side visible

Sir Blue Henry · 12-02-2012, 03:33 PM

Never mind - turned out to be a 20A fuse. Just havnt seen that type before.
soldered back on and ready to try out

Sir Blue Henry · 12-02-2012, 03:36 PM

Got if firing over a little - only when pushing it.
tried many times and each time it was sounding a bit better, 1 pop, 2 pops, 5 pops
figured it responded best with full choke but no throttle.

after about 12 pushes all in all, i got it idling, but dies as soon as any throttle was applied.
at this point it then responded to the starter starting it.

I let it idle for 5 minutes, gradually testing to see if choke could go back in, and eventually yes and then it responded to throttle.

Sir Blue Henry · 12-02-2012, 03:40 PM

went to end of the road - very nice
came back - got my helmet and went for an awesome 10km ride
took it up to 100km/h
what a fun ride!
so happy it runs like a dream.
Just a bit sorry its not one of those bikes you get on start and ride away - like my fj1200, but its more fun.
It isnt going to out accelerate anything - except maybe old folks on mobility scooters - just kidding - no it goes fine but it is just a single 250 four-stroke, but for what it is its exactly what i want, a light, narrow, simple air cooled bike.

That was such a great ride. will do another ride later

Sir Blue Henry · 12-02-2012, 10:42 PM

Did another 10km - very nice ride - didn't quite make it over 100km'h but still it went well.
after riding my fj1200 for an hour that was quite a change, but the little bike is fun. A 2-stroke would be nippier but anyway - all good. Now to start taking it apart for a cleanup.
