It was the best Harley I ever had with thunder heads and N20- and my favorite HD of all time. They were really disrespected by the HD guys when I had mine back in 82-84. My stock Z1 would beat it most of the time though, even with the N20. Once Honda invented the inline four with the integrated trans, HD could never compete again in any sort of racing without major handicaps. Only Vtwin to hold it's own after that against four bangers have been ducatis.
Interesting fun fact- one of my favorite Italian bikes was a company started by HD called MV Augusta. The 312 2+2 M/V goes 200mph bone stock off the show room floor, and is race ready "privateer" right off the bat. It is a 100k dollar motorcycle. To make a honda competitive with it, you have to spend about that much LOL.
