This is a pretty offering.  The rider in the video should be flogged.

 If it has the close ratio transmission , just keeping it running in 1st gear is a pretty good feat . Carb has no idle circuit and the megaphone means it won't pull at low revs , getting it going fast enough in the parking lot to clear its throat means probably 35 MPH .

I've seen these go for upwards of $35,000.

Because the engines are available new now, who knows how high this one will go?

I bought this 1948 350 Manx a couple months ago ,,,,,, not street legal of course but because the previous owner who had it for 3 yrs. never tried to start it there was no way I was going to let that happen to me. Why have it ,, No kicker ,, just bump it or roller starters ,,,,,, found a friend who has one and he lives out in the country with a nice long newly paved road ...... we figured out how to start it and now I can say I've ridden and own a Norton Manx ..
It's loud and light weight ,,,,, brakes suck ,,,, and won't idle with the remote needle type carb but it likes to spin up the rev's

I expect there's gobs of legalities & red tape & concerns about old tires and such, but one would think that even a tame tour or pass along the front straight of the actual Indianapolis Motor Speedway would have been a no-brainer for the test ride marketing video....

Super cool bike, even if trying to street ride it is akin to doing the same with a real XR750.

Oh she sounds ready to rock. A shame there was not enough room to come on the cam. Barely had the clutch fully disengaged with that tall gearing. (The brits thought of it that way back then. Makes sense to me.) Another 500 rpm and she would have started to sing.

 Some absolutely useless information about the Manx motor . In the repair manual the torque spec for the crankpin nut stated something like "weld a one and 1/2 inch socket to the end of a 6 foot long bar" . Read somewhere that the average Englishman in the 1950s weighed 150 LBs , meaning the torque spec was 900 lbs feet  :shocked:

I always used the straw, TDC and a piece of cigarette tissue in the points with the lever on full retard on mine.  Seemed to work. <shrug>

Nice  :thumb:


My Dad had one of these back in the '50s (before I was born), unfortunately he got rid of it shortly after marrying my Mother as it was 'decided' that racing was not for a married man, especially after a crash landed him in hospital.


I don't suppose he got a lot for it back then, if only he'd kept it and left it to me...   :sad:
