imrotting: This is a race bike & tuned for the track only. The Amal GP carb has no idle circuit. Therefore, unless the throttle is held open I assume the engine will die even if it is at working temperature.
I suppose it was the practice then that the riders would bump-start the bike & leap aboard in one motion. If that is right I would have thought the bikes would have been warmed up in the pits to ensure they would fire the instant the clutch was dropped.
@NJPurling The AMAL GP carburettor did have an idle circuit via the 'Pilot Screw', though the valve overlap on a Manx Norton meant there wasn't much point in trying to use it.
notice no low end torque thanks to the open pipe. Straight pipes are great for high end horsepower but you lose any low end thanks to the lack of back pressure. Still sounds amazing though. I can see why some people have decided to make Manx-esque bikes out of the thumper 500 Yamahas and whatnot.
My old bike, late frame, 54 motor, 7R gearbox, bacon slicers on the front hub because it`s cracked! Ray Petty rebuilt the top end in 1984, sold it in the late `90s, regretted it ever since……

Thanks for sharing :D
Beautiful Bike.
There aren't many bikes that look as 'right' as this.
@imrotting You've clearly never ridden a Manx; they are not noted for their ability to tick over…
Not the original front brakes ….
nice Yamaha FS1 in the background

I had and raced one of those back in the 70's. The sounds of a grid full leaving the line at Brands Hatch was music to my ears.
I'm pretty sure that fs1e in the background just shit itself
if the engiine number is 11um53 then thats my dads old bike!!
That, and a VERY appreciative crowd going nuts about the bike. Goes to show that not any performance will go well without the appropiate setting.
it pootled round the track like a caged wild thing longing to be free on the open road
manx,ajs 7r,bsa dbd34gs,matchless g50 real bikes for real bikers,

sounds like my old Ducati 450 single. I'd love to ride that thing one more time.
Well I like the sound and I like this old bike but: it's much ado about nothing … nevertheless: Thumbs up!
please bring these days back again
I used to watch Ray Petty building his Manx Norton's years ago.
