Hi Gentlemen,

I've managed to get the KE100 to start, I simply replaced the spark plug and all is good.

I still have no battery connected however.

My main concern has now moved to the fork legs however. I have been trying for a couple of days to part the stanchion from the fork leg lower. According to the Haynes manual, once the spring, top cap and oil are removed, you should just be able to pull the stanchion out from the lower. However, I have been frustrated so far.

G tried to pull the stanchion out too, and we even tried pulling it like a huge cracker. There is no bolt on the bottom of the leg, it just has the spindle hole welded on, as a piece of tube. There are no ways for it to come apart, as the end cap is also welded on.

So, I can surmise then that the Haynes manual is correct, and the damping consists of the spring floating in oil, but I can't get the stanchion out!

I need to change the fork seal as they are leaking heavily. I have also tried drilling a hole in the seal and pulling at it with a screwdriver and other tools. No luck.

Any thoughts on this? Smile

Indeed I have. And there is a smooth bit of metal which looks like a crosshead screw. However the edges are smooth so I seriously doubt that any tool would get a purchase on it.

I have to say that the flash on my phone was very useful for looking at that.

In the Haynes manual it just shows an end cap, o ring, stanchion, bush, spring, and lower, not including the fork seal, the fork seal washer and the circlip.

There is no damper or damper rod, and the manual explains that you need to use the 'slide hammer action' of the stanchion against the fork seal to remove it. However I've had the leg in a vice and pulled as hard as I could and the damn thing wouldn't come apart, so I'll entertain any suggestions at this point!

No Cir-clip holding the seal in place? No bolt / allen key hidden in the depths of fork leg ?

Bit of an aside, but it wouldn't be the first time a Haynes manual isn't quite correct. According to my manual, my '95 CBR should have one type of front fork; but it hasn't. I spoke to the people who work at Chiswick Honda and they say that type of suspension was only added to the '97 models and onwards.

Take what you say with a pinch of salt, and in my experience you should always back up your Haynes with a proper service manual for your exact make and model.

Thumbs Up

Well the suspense is over.

I got the fork apart and the Haynes manual was quite correct; I drilled a small hole in the fork seal and then it came out using 'slide hammer action'.

There is a damper rod in the bottom, but the stanchion has nothing at the bottom to hold the damper rod. Its just a rod the shape of a needle valve and must work by forcing the oil past the rim of the valve and the inside of the stanchion. Its basic, but hopefully effective.

I now need to do the other leg, and I'm laughing!

There was a circlip and washer over the fork seal (or so I'd guess, they were gone when I saw it.)

Correct.

And judging by how difficult it was to remove the fork seal, I don't think there is any danger of the fork legs coming apart any time soon.
