Great video your enjoying the bike even though it has teething issues that can be sorted .. Should have shouted for a spring compressor got a few here grab one when your about .. 👍👍
Old bikes , always fun of surprises. Never underestimate their ability to confound and exasperate you . But always worth it in the end . New valve guides and a seat cut . Not a huge deal for a guy with your ability . Piston looked very oily , might wanna check breather , I'm not familiar with Norton singles , so I might be talking out my arse . Sometimes I use two gaskets on rocker covers , each one Wellsealed to metal surface and copper coat between them . Better than grease which melts and runs away , I find . But I love copper coat , especially on toast .
Copper is proper. A popular fraise with local plumbers. I could just let it leak and buy shares in an oil company. And you are right, the piston is a bit oily. I prefer to dip chips (fries) in my copper slip as I'm not a big toast eater.
Due to the scarcity of quality old 'do-er upper' bikes that haven't been restored by now, this has become a good series although a shame some details go unrecorded. Please get rid of those very 'unNorton' blue sponge/flannel(!) tank mounts and the ht lead. I would do some research before opening up the inlet tract, sometimes velocity is more important on a mildly tuned engine than a percieved improvement by enlargement.
What's wrong with the blue flannel??? Just think how bad the ht lead would look without the flannel to take your eye from it. Don't worry about the inlet port, optimal cross section area is normally between 75% and 78% of the valve diameter. As standard these heads are only 62.5%. Norton left plenty on the table. You are right about the importance of velocity. The exhaust port on the other hand, is far too big. Thank you for watching.
