Time to go back on the engine. High spots knocked off from head and piston. New exhaust valves lapped in and fitted. Piston lightly blast cleaned on top.

Assembled the engine, some difference in compression now when the valves shut tight.

There were no markings on the cam sprocket but I put the lobes lika a V, intake and exhaust lobes on equal distance from center with piston at TDC. This aligns the cam sprocket bolts with the cam cover case split.

Kicked the motor for quite som time but couldn't get it to start.

I have spark and the plug is gapped to 0.7 mm. Spark serms fine but I have only tested with no plug installed. Coil is new but I have not measured the stator DC resistance.

Pulled the carb just for the sake of it although I had already cleaned it. The o-ring at the choke jet is kind of hard, how much does this influence. And look at the attached photo, should there be a jet or a plug below the inlet valve (below as in the photo)? The hole is threaded. And how much should the slide be open (idle adjutment screw). I have the mixture screw two turns out from bottom and needle at second groove from bottom. This is the PHM38.

Just checked with a flashlight and the threaded hole with nothing in it is a blind hole.

Pilot is 52, needle K32, emulsion tube AB265, choke jet 45 and main jet 180.

Did I read somewhere that there should be another jet under the pilot jet? I don't have one.

The jet you are referring to is called the CDI jet. Some carbs came with them. Some did not. It is generally considered helpful for starting if you add the jet if yours did not come with one.

What method did you use to determine TDC?

Tdc found by using an indicator clock in the spark plug hole. Tdc matches a mark on the flywheel with a mark on the right engine case. Cam chain fully streched on the "pull" side (streched on both sides really since it's a new chain).

You may try pouring a little gas down the spark plug hole. If it runs for a bit its probably a fuel issue.

Lean the bike all the way over to the left to get fuel to the petcock side. Don't rely on the fuel pump on a first start up and / or fill the tank to the brim to insure fuel gets over to the left side.

Make sure your fuel cap vent hose is unobstructed.

You probably did this but if the pilot jet is plugged, even a little bit, it probably won't start. Use a torch cleaner to ream out the crud in the jet. The holes are so small and the old fuel gets so hard that sometimes it not a bad idea to just get a new pilot jet to rule out that issue.
