Spada is still suffering from unknown engine gremlins. It's relegated to the unpopular corner of the shed for now.

I'm certain it has a new wheel on the front now. And a new tire or two ?

Doesn't rev over 5k rpm. It just coughs and farts and goes nowhere.

So far as I can see, the wiring is sound. Timing is spot on. Cam timing is spot on. There is no leaks in the inlet/head/exhaust. Motor is stock except for shorter pipe. Compression is good. Valve clearances are good. Not sure if its the stock carb, but its about the same size, just a little keihin round slide job. Have tried jets from 105-122, doesn't seem to make a difference..

Obviously I'm missing something, but I can't figure it out..

Fuel, air, compression and er...... ignition might be more than the plug.
but by pass the kill for a start.

I had the same problem when I put the engine in my new bike. Was the carb that had been kicking around on the bench for quite a while. Engine would only rev to mid throttle. Cleaned it and all good.

I had a mainjet come loose (because i didn't tighten it i guess) ran a bit rich over 1/2 throttle surprisingly

ie would run over 1/2 throttle

Put a timing light on it...sounds like it's not advancing.

5K is where its starting to make power and cylinder pressure, so possibly an electrical breakdown under load in the coil, cap, plug or black box.

Dad tells me TZ's sometimes had a similar problem and it was the spring in the kill switch going into sympathetic oscillation at a certain rpm allowing the button to bounce around killing the motor like a rev limiter.

Come to think of it, the kill switch doesn't actually work now. "On" is on and "off" is also on. If the switch is poked, maybe there is another bad connection.

I'll remove the loom (3 wires), strip all the terminals and solder them.
