I have owned this MkIII Norton 850 since the mid-1980's, and put most of the miles on it.  It has matching numbers (Chassis = 330265 and Engine =330365)  and remained original (with the exception of a Honda seat) during my ownership.  It has been regularly maintained, and has had a couple of professional valve jobs, and a rebuilt transmission.  In 1996, the transmission main shaft was rebuilt with roller bearings,  and the gas tank was professionally sealed.  Since then, the Amal carburetors have been rebuilt as needed. 

During that time the electric start never worked.  All electric starter parts seem to be there, but I think that it is missing a gear in the primary chain case).  Even so, it always started on the first or second kick when properly primed, so I never bothered with it and disabled the starter button. 

It has a Barnett clutch which has never slipped.  The muffler to exhaust pipe connection has been welded.  The speedometer glass has a crack.  The tires are old, and the rims have some corrosion. 

In 2000, I installed a Boyer electronic ignition and it ran beautifully.  Due to the press of events, it has not run since 2003.  In 2010, I had the tank and body work painted metallic red, and started working to get it running again.  That is when I discovered that it had no spark.  The lights, blinkers, etc. were fine, but no spark.  It has been kicked over periodically to circulate the oil.

Currently, the bike kicks over nicely and has full compression.  I'm selling this fine motorcycle AS IS with my collection of miscellaneous Norton parts, manual, some special tools, decals, etc.

Shipping is local pickup.  Otherwise, the buyer is fully responsible for all shipping arrangements and costs.  I will assist in whatever ways I can.
