Two legends came to see today, one for the last time.

First, some young vets that I am fond of came in to pick up a sweet bike that got a few upgrades, we talked about motorcycles, guns, and so on. Somewhere in the conversation, I needed to tell them a story about a much older veteran, and good, old friend, THE Legendary Jerry Spence.

I said to them, "Wait! He's like Beetlejuice! If I say his name three times, he will come in this week!"

Well I s**t you not, friends. Later that day, BOOM!!!! There he was. He was coming to see me on his way to do something very important. He was taking an old friend's remains to spread down Hwy 81. This was the desire of our friend, Malcolm "Pappy" Foster.

I first heard of Pappy when I was rebuilding the first motor that I ever rebuilt in a real motorcycle shop (Bryan's Harley-Davidson), the right way, under the somewhat watchful eye of Bill Hicks - my first real mentor. I was excited to do the job, and very eager. It's all I wanted to be: a motor builder, like Bill.

I was very excited to see that someone had stamped the coil bind (point where the valve springs are completely collapsed and bad things happen) up in the top of the heads. Why would someone do this? To experiment with different cams and know what they could and couldn't put in.

"Bill, look!" I said excitedly.

"Yeah, that's Malcolm Foster. He thinks he's God's gift to motor building."

Bill and Malcolm were not friendly, it would seem. Hmmm.

On the inside, and front motor mount toes, it was stamped: BUILT BY PAPPY

At the time, he was in a federal hotel, and not free to do whatever he wanted to, if you know what I mean.

Not so long after the Shovelhead, I did a 47 FL motor for Tom Oas. That's the way dealerships were, back then. A few years later, I was working at a Biker's Dream franchise that was later to become Super Bikes. In walked a guy that looked like one of the Fabulous Furry Freak Brothers. He had a S&S Super B in one hand, and a L series (first S&S carburetor) in the other.

He said - in a Louisiana accent, "Yeah brother, I just got out of the joint, and I'm just out trying to raise some money, trying to sell some motorsickle parts."

"What do you want for that side bowl?" I asked. That's the L series, by the way.

"Man, I'd take $100 bill for that." he answered.

I pulled out my purple Velcro wallet and pulled out $100.

"My name's Pappy, by the way." He said, smiling.

"You're Malcolm Foster!" I said, probably eagerly.

He was taken aback that I knew his real name. I explained that I had rebuilt one of his motors a few years back, and how impressed I was. He relaxed, smiled, and we began talking.

The next time he came, he had more parts, and his good friend, Jerry Spence. Not long after that day, we hired him. Jerry Spence became a regular, and I grew to love them both quickly. I think it was 1995.

Malcom came from a time that performance parts were few, and a guy had to figure out a way to make, massage, and modify parts to go fast. He was really more a biker scientist. He kept meticulous notes of everything he did to every motor. He was brilliant. If he loved you, you were in. If he didn't, man you better not cross him, because you'd be on the ground, bleeding fast. He was the absolute genuine article. He was in California during the chopper birth, in magazines, and a member of a club that I will not mention. He had stories of biker lore and adventures that he, Raymond, and Flash had. I couldn't get enough of them. He punched the boss in the face one day, and that was the end of his employment with us. Sad day.

Years later, we opened this shop. I had become a motor builder. Who was I a next door neighbor with? His son, little Caleb. One day, during that first winter here, Jerry brought him to see me and the shop. We bought a few bags of Braum's burgers, and spent several hours laughing, reminiscing, talking about motorcycles, etc. it was a great day, and became a great memory. He died in 2025. He was born in 1941.

Today, Jerry brought his ashes in, a few pictures, and we reminisced. He put his box on my police seat tool creaper that I made working at Bryan's. He used to sit on it when I wasn't using it when we worked together.

I would love to hear his voice, and see his smile as he told me one more story about Raymond, Flash, and himself, and call me brother.

The picture in the shop is at Willie Looper's Chopper Stockade on May Ave. There he is, porting some heads.

The picture of Jerry was him heading out the door today to send him down Hwy 81 in the wind, where he belongs.

I am the wind. That's sometimes what I say when I am on the road alone. He's in it now. Rest in peace, brother Pappy. You are the wind.

Joe Panhead Angelo's dream Panhead.

What kind of a guy is Joe? Friday before last, just walked in and gave me a fretless bass that he put together for me.

The stakes are raised, people. People have brought me tools, fi****ms, motorcycle parts, one guy even gave me a 1967 XLCH. But musical instruments? Joe knows my real language.

Thanks Joe Angelo!!!

Joe's 1951 Frankenpan little stroker.

I seem to have lost a lot of the pictures, but this is my old friend Joe Morrow's. Early o-ring heads with Shovel seats and a lot of welding (previously done), early S&S 4 1/2" arm flywheels, S&S pistons, Kibblewhite valves, Sifton solids with springs (helps Pans not lose oil pressure at the rockers), Andrews cam, and a lot more. Somewhere earlier on our page you will see some case repair and mating.

Labor of love. I love Panheads, but MAN do they work me over!!! It came out tight, solid, and beautiful!

My favorite rocker covers, favorite push rod covers, favorite gear case cover. I believe it is getting a two throat S&S carburetor.

Thanks Joe!!!

First seat with the new machine. To say I am very pleased is a huge understatement. They are from Joe's 51, and some heavy hands had definitely been in there, but the machine made very quick, neat, and precise work out of it. Can't wait to do more!!! Matt's Sportster Evo heads are already on it.

Playing with the new toy.

This is a Winnona cylinder head seat and guide machine, but man does it shine for a lot of the "drill press" like work I would normally do in the milling machine. Because of the multi-angle, floating air table, setup is a breeze.

Normally, I would my Jim's fixture to drill out this broken exhaust stud. The customer had already tried drilling, and was pretty off center, I used my Jim's tool to make the stud hole level, and used it to find center of the hole it's, then plunge cut with a 1/4" end mill sticking way out of that ginormous chuck to make the damaged stud flat on the end, so I could switch to a drill and drill it out. It was cutting so well, I just kept going until the chuck was in the way.

Since this is a video, Facebook won't let me add pictures. I'll put some in the comments. I love this machine!!!!

Frankenstein Aftermarket Panhead Transmission

This one started off as a lot of aftermarket parts. It had a long list of bad assembly problems, parts that didn't go together, a wallered out hole in the case where the main drive gear race goes, and SO much more.

We first machined out the egged out race area until it was true, then made a tool to hold the race to machine down a sleeve, then made a sleeve, then pressed it together with 620 Loctite, machined it down to as thin as I was comfortable with, then machined the case for an interference fit, then put the case in the oven for an hour, more 620, and pressed it in.

THEN lapped the race. If you look in the picture of the race with lapping compound on it, you will notice a shiny spot at the bottom. That means it isn't round yet, and we gotta keep lapping.

After it is round, it is measuring and math time, then put in the 44 or 43 bearings (depends if they are oversized), and measure each one. THEN put em in, check endplay, and assemble the mainshaft side.

After fitting the countershaft bearings, it's time to check the endplay. .003". Nope. Too tight for my liking. I like em loose like .010" to .013". Problem: it already has the thinnest variable thickness thrust washer they make, and I sure don't want it thinner. Solution! Surface grind the countershaft cluster.008". Assemble, check, BOOM!

Next we put in the new shifter forks and set up the centering. Finally, the rest can go together.

Sunnen hone the new kicker bushings, and send it!

I wish this one went as easy as that all sounds. So many parts that were made by a lot of different people. So much together, apart, together, apart. Really wore me out!!!

In the end, we have a very tight, very solid four speed with quality (Andrews, Eastern, and Jim's parts. So long as it stays full with the right oil, the primary and rear chain stay adjusted correctly, and not too tight, the clutch is adjusted correctly, and it isn't badly abused, it should last a long, long time.

Now back to Joe's Panhead motor!!!!
