Main function of the carpet Ted is put there for the build, giving the frame and engine protection from getting the paint scuffed off. Great for protecting all the components, chrome etc. Now that the bike is rolling the carpet will be removed until the next build. 👍

Lovely bike. I was to comment on those blinkers, but then I read Bryan's comment. I couldn't beat him. :D
Shame about the US frying pan indicators

Have you got a red carpet for "Launch Day" when the bike is finished?

So here’s the confession - after filling the carbs with fuel and quickly discovering I hadn’t closed No3 carb drain screw 😡 I pressed starter button and turned over to nothing more than banging and cracking and misfire I quickly realised something is not right. I kind of ran out of time and left it til later in the day buying myself some thinking time. My instinct was to check valve timing which I did and resulted in the realisation that they were not set right. I had set the valves when I assembled the top end but had set the valves on the exhaust TDC stroke and not the compression TDC 🫢. Anybody tried that? Just me then! After setting them correctly all is well, fired up immediately and running well maybe try a carb sync see what like when I give it a right heat up. Slight leak at camshaft end cap mounting bracket. Is these aluminium sealing washers still available?

I always find the first 20+ miles on a rebuilt engine a nervous/fraught time. Especially on a 2-stroke, Best have a change of underwear tucked into the tool kit as well.

First start up rides always fills me with apprension, I remember one of my early runs on the 400 during its two cylinders only period (plug leads not in correct order) as I'm going up a fair hill the engine started to die. I pulled onto the pavement to look on my phone for breakdown recovery. That's when I turned the petrol tap to R, it flooded a carb, tarmac was stained, I thought for a moment it was engine oil. Rocked the bike, rode home on 2 cylinders. Wow was it a different bike when I switched the leads. Rookie mistake left coil to one &  two, right coil to three & four. I beat myself up with that mistake.
