1928 jdl

[exeric]

Mark, are the JDL cylinders different than the standard JD cylinders; and are they the same as JDH cylinders? If any of this is true, what makes a JDL cylinder different?

Probably not a factory racer if it's a JDL. That's just a standard road model with some sporty options like smaller wheels, narrow tanks etc. Factory racers would probably have been an FH or FDH engine.
That's not to say that some privateer didn't use that engine to make a racer at some point.

A friend of mine found a 1928 JDL....he thinks it may be a factory racer. My question is....did they make a factory racer in 28, and if so could someone post some pics of one.
I'm sorry I cant give any more info....but I haven't seen it. Any help would be greatly be appreciated.
Thanks,
