The knuckle & panhead motors of today benefit from advances in technology. Modern replica knuckle cylinder heads now have the later 1954-1965 O-ring intake manifold, that eliminates the troublesome (leaking) large-hex "plumber nuts" of 1936-1953. Over the last 35 years the aftermarket Harley parts for the 1936-64 OHV Big Twin motors have leveled-off into less choice, but higher quality. The 1954-57 rigid frames that will be returning to market, all have fixtures welded or brazed for the immediate fastening of parts to frame.

Creating this book was a mountain of work for me, with most of the mechanical facts provided by Mark Stettler. I "brained" the Panhead cover-gasket procedure and some other tips, but the push rod adjustment, motor fit and clearances are all from Stettley.
Mark "Stett" Stettler has worked on motorcycles for forty years (and not all of them on Harleys). An M.M.I. graduate, (Phoenix, AZ.) he was Top Student in his first (7) clinics (scoring Perfect, in both 2 and 4 Stroke Performance). He was Top Graduate in the Early Model Class, scoring the highest score in the history of M.M.I., on the Early Model Final (i.e.; top 99%-tile); and top Graduate in his class in Late Model Electives #410, Stett was hired three weeks before graduation by San Diego H-D. He stayed with the dealership for four years as an engine builder and machinist; during which time he completed all (per full week) required Update Classes, in Milwaukee and Phoenix (i.e. Engine 1 & 2, Chassis & Suspension and Electrical Systems). I list his levels of technical knowledge because, in my opinion, mechanical discipline is a developed skill.
Mark opened "Stetts Iron Horse Ranch" in El Cajon, California, in 1997, as a factory certified H-D Master Technician. Over the past two years, Stett’s crewed with well-known "Bonnie" Truett (of Truett & Osborn fame) and built motors for the AHDRA Race Team entry "Nasty Habit," for rider and owner Kinzie Bolson. All mechanical facts in this owner’s guide have withstood scrutiny and we welcome any suggestions. (A government engineer/enthusiast uses our book in his lecture circuit, and took the time to review the information and questioned us, as to whether or not there was an "applied force" not calculated [in our zero correction] for a torque wrench "foot adapter". The engineer was going to contact us if his own textbooks proved an error, but all facts remain unchallenged to this date).
Our clearances for valve stem to guide bores are tighter than OEM clearances, because modern valve machining is capable of creating a more exact fit. Earlier valve operations relied on loose valve stem to guide tolerances, as the in-line boring equipment of the 1940's and '50's was not as precise, and the valve needed to "find" its' seat. The end result of yesteryear did not produce as accurate an in-line assembly, once the procedure was completed.From the Author:
Page 50: Do not tap the oil pump check ball with a brass drift as suggested. A seat-burnishing tool is being developed elsewhere.
Page 108: To set the points, put the centerline of the fiber-rider at the highest point of either cam lobe.
Page 139: Torque the (4) "Bestway" seal plate bolts criss-cross to 20-ft. lbs.
Page 155: The gear puller is available from Pep Boys Auto Parts. Manufactured by Performance Tools, Kent, WA. - Part # W139 or a 3-1/2" (smaller version) puller, part # W140.
Page 268: Under the Snap-On adapter (foot): This is because the foot is at 90 degrees to "the head of the torque wrench," and not "the head of the bolt".
Service Tips: Linkert carburetors that flood with gas can have float or float valve problems, but also look for casting slag left in the interior of the float bowl, that can snag the offset (cork) float (if gas-logged and swollen), which will keep the needle from seating. Remove the rough area with a Dremel® burr.
If you own an original, or you're building a V-Twin (Tedd Cycle) Replica Knuckle, you will also need the H-D (OEM) 1940-1947 service manual. If you own an original, or you're building a V-Twin Replica Panhead, you will also need the H-D (OEM) 1959-1969 service manual and the Clymers Panhead manual. And, for general reference you will also need the Bruce Palmer H-D Restoration book. The above mentioned service manuals are available through Kick-Start M/C Parts, (616) 245-8991.
