Any love for the Norton 16H ?

Postby speirmoor » Mon Aug 07, 2017 8:25 am

The more I see them the more I like them. Does anyone here have one? It seems they were never imported in to the USA in any significant numbers but have been brought in by enthusiasts. Canada may have gotten a few as the were used in the military by some of the Commonwealth nations.

Something like this?
Definitely a case of making haste at leisurely rate, they slow down at the sight of a hill.
A hoot to ride though, just not on a busy road.

Thats the oil tell tale, sprung loaded pin which pops up when the engine is running, shows there is oil pressure.
Supposed to pop down again due to the spring once the engine stops but often needs a little help.

If memory serves correctly, I think the 16H was specifically designed for military dispatch riders and only made it into the consumer market after the war. The market was flooded with sales of the dispatch rider's bikes at much lower prices that new factory bikes, so the 16H wasn't a big seller when new on the consumer market.

One of my colleagues at work had one one of the military ones in the late 1950s and let me ride a few times. My 150 Vespa was quicker!

The 16H was a civilian model introduced in 1921.

http://www.nortonownersclub.org/models/ ... side-valve
Over 100,000 of the WD version of the 16H were manufactured before and during the 2nd. World War. The chosen design was based on the 1937 civilian 16H with open valve gear, the higher clearance trials frame, a crankcase shield, buffer stops on the forks and lower overall gearing.

They are rare in the USA. I guess they were never imported in any great numbers here. Some suggest Canada may have gotten some in to their military? I've yet to see one in the flesh.

OK, do you need to machine the valve cut out in the piston deeper :?:

Fitting an OHC engine to a 16H might make it fly.

Seeing its the same chassis / running gear as the Grand Prix suckers pre war , if itd fly thatd be good .

Apparently there were a few tweaked ones about that wernt slugs .
The Japanese response to ' styling ' , was to add more .

The OHC and ES2's had the cradle frame (frame tubes wrap under the crankcases) whereas the sidevalve and model 18's had the diamond frame (frame bolts front and back to the crankcases).
But the sidevalve can be made to go, there is a good article by Paul Greet on the VintageNorton website outlining mods he has done to good effect - for a usable road bike.

i thought the standard ES2 piston was flat topped... so would have thought not... its the duration or dwell whivh gives longer valve openings ... no harm in getting the plasticine out to see how close the inlet valve is on full lift..
