Well, guys, after 18 months of gestation, I received my first three production heads on Friday. I didn't know they were coming so early so the photo is crap and doesn't do the thing justice. This particular head is going on my '73 850 Roadster this week. I should be riding it next weekend.
The heads are absolutely beautiful. A piece of functional art. Specs are as follows;
6061 T6 aluminium
All standard Norton parts will fit right on.
Externally identical to a standard Norton head, except the finish quality, which is exceptional.
Ports designed by James Comstock.
Phosphor bronze valve guides
Seats suitable for unleaded (of course)
850 heads available now, 750 heads in next batch of ten
Lighter than standard head
Stronger than standard head
CNC machined, including combustion chambers for identical volumes.
Satin blasted external finish
More meat around exhaust ports
Half inch valve guides on both 850 and 750 heads. The larger factory 5/8 ths guides on the 850 being unneccesarily large.
Valve seals included
See Mick Hemmings in the UK, Matt at Colorado Norton Works in the US and Ben at British Imports in Perth, Western Australia on (08 9375 9755).
The rest of the world can contact any of these three gentlemen, as they will be the only distributors. Dealers, contact these gents for pricing.
Any questions, ask away.........
