1955 AJS Model 18CS Desert Sled Scrambler

After several months of chasing this AJS I finally was able to purchase it and introduce myself to the world of the Big British Single. This will be something new to me as I have always been more of a Twin Cylinder enthusiast. 


This is 1955 Model 18CS, a 500cc OHV Single. The CS stands for Competition Spring Frame.


Shipped from the factory as ready to go racers, they were very successful in both Scrambling and Desert events. This bike was registered for the street with the addition of a Head Lamp and Sparto Tail Lamp although there is not one wire on the bike! Purely to stop getting hassle from the man whilst out riding on the street I am sure. 


The CS Models were built in the AJS Race shop, basic Model 18's were taken off the production line and were given the business to produced a highly tuned thumper. Only around 200 CS's were produced   each year.


Love the hand painted graphics on the Alloy Tank, originally it would of been black with gold decal and lining.


Spark provided by a Lucas Racing Magnetos, a beautiful item, green tag and all.


Competition Oil Tank bares the decal from the original dealer who sold it new, Hunter Miller Motorcycles of Bellflower, California, mainly a BSA dealer.


I have a receipt dating from 1965 for some engine work including a new Alpha Crank Pin and Bearing as well as a used "H" Camshaft. 1965 Being the last year the bike was registered, it had been in the back of a garage until I pulled it out this March, 2014. 


Attempts to start it were set back with the clutch slipping every time I kicked it over on the compression stroke. Removed the plates and soaked them for a while, reinstalled, adjusted and job done.


After removing the Amal Monobloc 389 Carburetor for cleaning and the installation of a new spark plug and several kicks later, the old bike fired back into life filling the nearby vicinity with plumes of white smoke. After draining the sump and adding fresh oil I was able to go for ride. The motor sounds great, very quiet and smooth with tons of power.


Will be looking forward to riding this over some fire trails in the near future. Until then I will be searching for some Dunlop Trials Universals.....
