Question about V-twin mfg. replica panhead motors
JHSTANG51
Double round of sex on the beach for everyone.
Has anyone here bought one or have any feedback on these motors? I've always
wanted a pan, but shyed away because of weak bottom ends and oiling problems.
I'd love to build a bike with one of these if they working out for folks. Also
interested in any feedback about the replica knuckle motors they make and the
trannys for them both that they also sell Please post your opinions good or
bad.
Thanks,
John H.

I've owned two panheads and several knuckleheads and have had no
unique problems with what you term as being a "weak" lower end. First
off, the knucklehead and panhead 74" lower ends are exactly the same
from 1940 through 1952, and although they changed the right side
pinion shaft on the 1953-54 models, the flywheel and rod assemblies
from 1940-54 are exactly the same..
The big change came in 1955 when they went over to a larger splined
sprocket shaft with dual tapered Timken bearings on the left side and
used 3/16" rollers on the right side pinion shaft through 1957 when
they changed to 1/4" double row rollers on the right and used them
into the shovelheads. Although the left side flywheel casting changed
slightly in 1955 to accomodate a larger taper on the mainshaft, both
side shafts used the same lock nuts from 1940-71 when the left side
sprocket shaft taper and nut were significantly enlarged for 1972..
With the exception of smaller gears and adjustable spring tension for
more pressure, cast iron oil pumps remained basicly the same from
1940-47 when a new cast housing was used from 1948-67 with which the
pressure was set with a fixed piston and spring. Then in 1968, a
completely new pump was designed from aluminum with significantly
larger gears. Ironically, the old knucklehead rocker arms were oiled
through an external tube, and though the 1948-62 panheads were fed
through internal oil passages in the crankcase, cylinder and head
castings, the design went back to the external oil lines on the 1963
panhead and kept it into the shovelheads..
There were further modifications and enhancements throughout the
shovelhead years, but with the exception of the changes already
mentioned here, the lower ends and oiling system changed very little
between the knucklehead, panhead and shovelhead..

Which brings us back to the original question....which was a request for
feedback on the replicas.
Morning, Joe.

I'll bet they are just like any other motor.
It depends on the skill and care in which they are assembled.

I was rebutting his comment regarding alleged weak lower ends an
oiling problems in panheads, with an elaboration on the particulars.
I don't know much about the construction of the repros, but I do know
that they're gonna cost boocoo more than an original panhead..
Goodnight Fins..

others (always consider the source). My thing is this, I can buy an S&S 124
motor for a little under $6000.00 or I can go old school with a replica panhead
motor. I've always loved them and like to be different. If the price is
relatively equal or people have had any bad experiences with them, I'd rather
go with a stroker and new technology. More bang for the buck or the classic pan
look with some tech. updates? I would think that the replica S.T.D. motors
would be cheaper. Just wondering if anyone actually has one and has a comment
on the quality, price, etc. I am in agreement that who built the motor has alot
to do with reliability.

The downside of the repro Pans is the use of foriegn parts like rocker
arms and pedastils (spelling?). The quality of those parts is way
below Harley's standards during their production years.
If I were doing it, I would build a Pan motor that looked stock but
took advantage of some late technology. Like good rigid S&S flywheels
and reverse rotating timing gears that would allow me to run
electronic ignitions produced for 1970-up Shovels and Evo motors. I
have hidden a few late ignitions in Pan distributors.

> i dont have sted return oiling back to the tank. and the oil in the tank is a lot cooler then the motor
capacity that the supply side , else the crankcase would fill up with
oil . Mine have all done what you're describing - one shovel and two Evos .

Pretty much it's shopping in the land of lowered expectations in the way of alloy and material quality, precision of fitment, etc. So it comes down to what your intentions are. If you're going to build this and drive around the block a few times a year, and just look at it the rest of the time, then V-twin will probably fit the bill. If you plan to actually drive this bike cross country and be reliable, I would steer you toward S&S for a modern, new pan.

> i have a return oiling poblem and was wondering if when i up graded the size of my motor by adding longer rods 40over pistons amd used the maching jugs that came with the pistons they were shovel head i put them on a STD KENDDNY CASE WITH REP STD PAM HEADS WITH EXSTERLE OIL LINES . NOW IT DONT HAVE THE STEDY RETURN OIL FLOW IT FLEXS ON OFF ON OFF
So half the discharge to the tank is air.
Terry is spot on!
