Or if nothing else is damaged, just remove it and use the manual decomp lever.

You weren't kidding about excess sealant..........it's even in the cam bearing!

Can you post more photos of the build? That looks interesting!

Cheers

I asked that question myself last year and got an answer along the lines of "he's doing fine down by the river".

The video doesn't show the hole in the camshaft. I was on several forums with a build thread but got fed up of being told it wouldn't work or it would be dangerous, so I took them down. I can post photos if I work out how to do it. Lol. The camshaft needs replacing so I'm thinking of going with the rallye cam for a bit of extra poke. Id really like to work out what has caused this and avoid it in the future though.

Ive ordered a new camshaft and bearings from the local ktm garage aswel as water pump seals.

this is what the bike looks like at the moment, I'll start a seperate build thread and link it, im not going to hijack this one.

A quick update, a short tale of woe, and a couple of things to watch for. After putting everything back together I had a hell of a time getting it to fire up.

I love the AntiGravity battery I put in last year. The bike sat for 8 months (August to April) without charging and the battery cranked and cranked. It would almost catch but never come to life. Only a few false starts and backfires through the exhaust.

Finally, using a little ether I got it going and it ran well when warm but felt a little bit down on power. It was a bitch to fire up when cold. I ran the Desert 100 this way but it was time to figure out why it was so hard to wake up in the morning.

Thinking the old gas may have plugged a jet I went through the carburetor. No better. Time to take the valve cover back off and see what is going on.

It turns out that the timing chain had slipped one tooth on the cam sprocket while I was working on it. The cam was slightly retarded so the exhaust valves were open a bit on the first part of the compression stroke.

Here's one something to look out for. With the timing chain tensioner out there is enough slack in the system to allow the mark on the cam to align with the top of the head like it is supposed to (rotated counter clockwise viewed from the port side) even with the chain off a tooth. So when you align up all the marks, check to make sure the front side of the timing chain is under tension, not the back.

Another mistake I made was to put too many shims on the water pump side of the rocker arm when setting play on the shaft. Only one 1 mm shim on the water pump side and then add or remove shims on the other side to get the correct play. Otherwise the rocker will make contact on part of the action.

I am a happy camper now that I have my wheels back and it's running properly.

Cheers.
