I think it looks great and is just what I wanted. Bikes running alright still a little stumble at 3.5k but I’ve got another needle clip position to try in the future. The front sprocket oil seal is now doing its job since tapping it into place but will keep an eye on it, just getting some drips from one of thof oil hoses which I’ll look at getting repaired when I change the oil.
Since replacing the washers on the fuel tap with dowty style ones as recommended by Bryan I’m not getting any more leakage through the petcock, I am however still getting overflowing carb bowls when the fuel tap is left on, just dribbles out. Have tested the brass overflow pipes for cracks and they’re all good, have swapped the replacement float valves with oem ones but still no joy. Pushing the floats up by hand stops the flow of fuel when the bowls are off

That is a great looking bike you should be proud of, been away a lot myself and need to complete mine, been on the back burner now for nearly 2 years, just the wiring, fuel system to redo, poss a new tank as mine as the pin hole syndrome and needs re-stripped. This has given me the jump start again to do mine. Thanks for sharing your build.

The drive seal wasn’t sitting flat as it should and was leaking at the bottom where it protruded out slightly. Unsure whether it wasn’t lined up correctly when I closed the cases or not but it’s not leaked for the first 50 miles until now. I even put a smear of hondabond on it as recommended in hondamans book so perhaps this held back the oil until now.
Rightly or wrongly I carefully tapped it back in flush and it doesn’t seem to leak any more. Am unable to ride as the seats with the upholsterer but fingers crossed it’s fine

Well, from looking at the picture I would say that either your drive seal is fitted backwards (inside/out) or mine is... I have no leak but perhaps I've just been lucky!

Hello chaps.
Well, unfortunately due a new family and other ongoing projects I’ve started thinking about selling the bike. Breaks me a bit knowing that the blood sweat and tears that went into the bike will never truly be reflected in the value.
What do you guys think the bike is worth?
I’ve not been on it for 6 months, there was a problem with the battery not always charging properly, front brake despite having a rebuild isn’t quite right (could just be it needs rebleeeing) and I never truly got the jetting nailed.
Oh and I went abroad for 6 months totally left fuel in it ;D
Basically I’ve zero time for tinkering so going to shift it instead
