Motorcycle MPG Guide: Harley-Davidson Big Twins

 

Yes, I know that the early 74 cubic inch V-twins equal 1200 ccs, but their lineage is "Big Twin" so they're in here rather than in "Harley-Davidson Sportsters & Below 1201 cc".

Hal,

I was hoping I could steal some information from you... rather than go through & transcribe the data in your MPG study I was hoping you might drop me a file with the information (( I am writing my thesis paper for my MBA & it would be very useful ... I will or course cite my sources and give you full credit ))
