It is satisfying to note that the Dunelt is making good, striking out as it does on new and hitherto untried lines, and yet with a definite reason for its divorce from Dame Convention. To combine power for sidecar-work with a low initial cost is the raison d'être of this machine, and we think that the makers have achieved their aim.
Cooling, or perhaps more correctly overheating, the inherent bugbear of the big two-stroke engine as a type, has been overcome by using a two diameter piston, allowing, a 50% greater charge than is ordinarily possible, and providing a flow of air round the piston trunk. Numerous little details have been improved since last year. The compression release valve now has a flexible tubing connection to the main exhaust pipe. The adoption of split roller-bearing big ends is the only internal modification of importance. Two thumbscrews allow the primary chain cover to be quickly detached, while all hubs have knock-out spindles. The cylinder, it will be remembered, lies almost diagonally in the frame, which certainly keeps the large, somewhat bare, outline from obtruding in the super aesthetic eye.
The machine immediately impresses one as sound and sturdy, yet compact and symmetrical. Evidently the lessons of the last Six Days Trials where the Dunelt gained two "golds" have not been lost on the designers.
