Beautiful, painstaking work, but I can't see how long it can last if the bikes are ridden. I know I can't keep my bikes so nice. Hell, I just fisished a frame-up restoration of a '68 FLHFB, and when we were loading it onto a trailer to take it home the trailer came off the hitch, wheelied up, and the loading dock tore up the rear fender!

I was curious about the slots in the valve heads, so I did a little search on Harley flatheads and ran across a manual for the 45. Looking at the specs, it had 5 to 1 compression ratio. Right when my little brain started to wonder why they used so little compression, I read a couple of lines down in the spec sheet and there was the recommended fuel octane listed.... 72 octane or higher!! SEVENTY TWO!! We are so spoiled with our modern fuels and oils! That little 45 put out 6.05 horsepower. But there's no telling how much torque that little fella made!.... I never did figure out what the "screwdriver slots" were in the valves :) Old engines are amazing!
@pacificmike9501
Жыл бұрын
Those slots will help use a driver when hand lapping those valves to their seats. The way to raise the compression is to lessen the size of the combustion chamber. On a flathead, that will limit the flow of the air/fuel mixture. You either get compression or flow. Take your pick. You can't have both. Go for the flow. When flying down the road, you won't miss high compression, but lots of flow makes it go. Or, build an overhead valve motor. We'll be getting into this more.

I believe what you are alluding to in your explanation of why a flathead can race is you are describing volumetric efficiency. Not only are you limited by compression ratio but you also have a 180 degree directional change for flow. If you use the big wrist pin flywheels and you are maxed out on your bore you will have almost 90 inches of flathead power. Great video my friend. Later bro.

Hey Mike. Is the transmission a 3 speed or can you make it a 4 or 5 or even a 6 speed?
@pacificmike9501

All of those Big Twin transmissions were four speeds from 36-79. Then came five speeds. There were 4 speeds in solid mounts and 5 speeds in rubber mounts. The only exceptions were 3 speeds with a reverse for Big Twins equipped with sidecars. There are no other gears sets I know of that can be installed to turn them into anything else. When they say 5 or 6 in a four, they mean a 5 or 6 speed transmission that will fit in place of the original 4 speed.

Hi Mike, do you ever get problems, (like we do with some British bikes) with these motors wet sumping with the gear driven oil pumps?

Once in a while. I don't do it often enough to be proficient. Quite often, I have Truitt and Osborne build the flywheel assembly and then I install it. I love new flywheels, shafts and rods.

Hi mike, You mentioned putting sleeves in your cylinders if needed. I’m looking to put sleeves in my ironhead cylinders. Just wanting to know are they safe once installed. By that I mean not coming loose in the bore.

I've used them alot. In fact, I'm running them in two bikes now. I believe them to be better and wear longer than the cylinders without sleeves. But, they must be done by a competent machinist. I normally send the to "L.A. Sleeve."

Mike I have watched a bunch of your videos and have learned a lot. I recently inherited a old sportster that has a 45 magnum engine in it. I can't find much information on this engine, can you suggest someone that may be able to help? Thanks in advance
@pacificmike9501

A "Magnum 45" is basically a 45" Flathead Harley with a 900 S Sportster overhead valve topend. There was a magazine article many years ago where Mr. Smith of "Custom Cycle Engineering" built such a beast and it showed all the details. This was somewhere in the very early 80's. We built one in the shop I worked in at the time. Check with "Cusom Cycle Engineering." They are a manufacturer of parts in California and still in business. Nice people. They can most likely get you all the information you need.
