I'm not aware of any?.. I'm only using a dropseat rear mated to a 1948 front for my Pan motor because I like the rigids 3 degree forward tilt of the motor. Love how that looks!! I believe all the...

Awesome man!.. Thanks for the tutorial, pics

It's hard to find data this complete for an individual runner H-D so it was interesting running it through PipeMax

Based on how easy...

never mind, got it

Hoping somebody can list their specs

I probably have it in an old catalog somewhere but try to find it :(

You might be interested in an interview with the man who developed the software.

It's suggesting that if I do everything right I can expect?.. as I have it configured now, pretty damn good for...

Alan Sputhe knew how to make his "polyspherical bathtub chamber design" work, no probs, and it looks like the valves have been splayed even more than on a stock shovelhead

Nothing more brutal or...

Ha, no!.. just a fan of his channel

I've never found a need for anything more than pipemax. It's easy to manipulate for very accurate results if you understand a few fundamentals... I first...

Fore sure!.. and since 2007 4 1/4 inch stroke is the shortest available from the factory IIRC. How quickly a thread can go off the rails here. I was talking about smaller bores, not stroke!!

How would any of us know anything at all now if it wasn't for youtube... right, some of us don't!! Best thing we could do for America is shut down all those babysitting services we call (schools) and...

Was that at least a few decades ago?..

Doug is retired now but I'm sure he learned a lot from doing it wrong way back then.

I think people are getting hung up on the word "bathtub", maybe...

Some of you may have guessed I've been exploring the possibilities for a 4 1/4 inch stroked 61 Pan, 61 to 74 inches. Before somebody says I'm doing it all wrong and I need to go with a bigger bore...

Thanks man!.. This thread helped me date a frame also. I received it with the head lopped off, all covered in thick, shitty candy orange paint. Based on what I was told and how it compared to others...

For some reason I can't access this site at the moment, but it's referring to your "3K" stamp

edit: I got in :)

Yes, you are correct!.. It would have been just behind the pin (where the pin should be) in the first recessed area just above the top of the backbone, a raised digit 5mm tall. What year do you think...

It's either late 62, 63 or 64... that's it!.. 1963??

Edit: there is a two digit die number on the right of the steering head also... 35 = 1962

35 or 36 = 1963... 37 or 38 =1964

I think that's expected (number inside on the right) if the exact same forging was used on both sides?

Your frame is absolutely genuine!.. Best to compare pics of your frame and one completely original (uncut) to determine exactly what was trimmed off.

Your frame is post late 1962. Some question as to when the number flip happened late 62 or beginning 63

edit; those hacked off bits are available from the aftermarket to restore your frame

I'll look in the book and tell you exactly, back in a minute

The frame is for real according to Palmer... My numbers are right side up and on the left. I don't have the book open so I can't say if your frame is early or later with any certainty, just that it's...

You are much braver man than I am to run the front tire offset from the headstock center. Harley finds it acceptable to dog-track the rear though. How much?

I'm worried you may encounter alignment issues attempting to place the rear tire dead center in the frame (perfectly aligned with the front tire)

Only referring to the far right #pic here. Nothing there looks like my 48 cases do . The pad on my case is exactly 0.100 proud of the case, belly number 148-2178

I guess Doug is retired now.

I ran his Evo HQ-0024 Rumble Stick in the Pan simulation and lost a few hp & ft lbs. I tried it at 10.5:1 also but still didn't recover the losses. And it made the...
