These pipes are small diameter 1 1/2".... I guess back in the day, the factory felt the K Model 750cc side valves worked best with these smaller diameter headers? Similar sized to the ports, etc. I always like the big, free flowing straight pipes, but so far, this thing seems extra responsive and hopefully it will help bring back some low end to this thing . . ? Factory stock early Sportster muffler. It's got a set of -60R KR heads on it, and I resleeved the cylinders, new valves, guides, etc. The Delorto PHM38 is my new carb-of-choice (if you don't want to run an M53 Linkert). I haven't really rode it around yet, so I'm sure I'll have some tuning issues coming up. Hopefully not - is always nice ! I added my set of -60 aluminum wheels (I'd been saving for who know what?) and figured I may as well start using some of this stuff.... One thing is for sure, H-D made some pretty neat bikes back with the Ks and early Sportsters. Some of the neatest lookin' if done right.
I bought these years ago outside, on a beautiful summer day in Anamosa at a vintage swap meet. I just thought they were so cool. I like to sell crap to fund my other projects, so I put 'em up for sale. Now they're off to Japan ! I've sold more stuff to the Japanese. Iron Sportster parts, panhead parts, entire motorcycles . . . It used to kinda piss me off they were buying all our American heritage...but after gettin' to know some guys that come to Davenport and chat on-line....I realize how much they dig these vintage Harleys(and Chevelles) as much as we do - and it's ok with me now. It's going to a good place. Sometimes guys are just weird.
I took the drain plug out, and I thought it was empty??? Huh? What the heck? Oh, there it is - all 4 quarts of oil took about 6 hours to drain. A small little string of oil just kept on and on near the end. No lie !
Now I got this thing for a "crusty" early ironhead swingarm bike - with a slightly over stock or springer front end. Short rear fender (maybe with a steel tail-light hiked up?), peanut tank, flaking chrome, vintage seat, maybe a painted frame . . . A bike you wouldn't worry about leaving outside covered with tarp - with a log chain around it. Never wash it (wouldn't want to rinse the grease out). We've had this 1970 ironhead engine with peeling chrome that would make a good mill....
