This 1948 FL is a done deal. real bad shape when it came in many moons ago. . . but now it should be a runner ! Runs a stock "H" grind Victory camshaft with fresh lower end, cylinders and heads. All pretty correct 1948 parts. The 1st year of the Panhead for the motor company.
May as well do the transmission while yer at it . . . correct date code case.
Super Nut ! Check your clutch hub fitment. Needs an 11T speedo drive. I leave the top loose so the owner can pour some oil over the gears. I recommend Bel-Ray Hypoid 85w-140.
For the clutch hub nut: I pressed in a new rubber seal, then put the old-style washers,
spring and snap ring on top to keep it original looking . . . Still runs '48 style oem pushrod ! The tank-shift-rod-lever was welded up and redrilled proper diameter.
I bought these (all rusty and locked up) at the Sturgis Swap Meet years ago. I carried them all the way on my bike - restored them with new shafts, etc. I tried to sell them, nobody wanted 'em . . . so I just found a set of cases (that need some welding) . . . so I may as well build a little motor. I got cylinders, heads, transmission parts, all the special parts that are 52-53 only, like clutch hub clutch basket, kicker shaft and gear, transmission shafts . . . on and on. There's hardly one part that will fit on a 52-53 K Model AND an ironhead Sportster. The cylinder base nuts ! That's about it . . .
Wait: The connecting rods are the same, wrist pins and clips. If you think of something else, let me know and I'll explain why it won't work.
The ol' 1952 K has pretty much the same chassis - with 1/2 the power. It's my favorite motorcycle. The K and KH were only made a few years for street use - but H-D pumped out the KRs all the way through 1969. The KRs were successful 'cause the flat power band kept the rear tire from spinning. They stayed hooked up and moving forward.
The Delorto "Pumper" carbs work great on side-valves . . .
Firestone (Coker) repop tire with stock muffler and shocks. Early XLCH rims.
-52 Casting Number (NOT -52A) It won't work on a Sportster with one-piece shaft/generator idler gear. This is for the K Model engine only (maybe a 1957 XL still had an idler shaft (like a 45 or a big twin)?
Last month I went to the Yucatan and stayed in Valladolid for a few days, then hiked Ek Balam and went to few cenotes. I like to stay near Punta Sur (on the south end)of Isla Mujeres too. This gal at Playa Norte was doing maintenance on her scooter in the street. Fixing corroded connections, making sure the lights worked, etc. She bought it new, it was stolen a few times, lost for almost 6 months on one occasion, but she always got it back. Nice gal. Everyone I meet in Quintana Roo and Yucatan are nice. Someday I'll take my WLA down there and get lost for a few years. I love it there.
