Rare

If you are running a CV carb and you are looking for the right parts to tune it this is where you want to go: https://www.cv-performance.com/
I put a CV on my Iron Head and could not get it dialed in. Jason shimmed the needle which helped a lot but it still isn’t where it needs to be. I ordered parts from CVP and initially they f-d up the order. I called and left a message and within 20 minutes got a call back from the owner Ken. Ken apologized for the mistake and sent out the correct part asap. He seemed so cool I asked for some free tuning advice which he happily offered and shipped me an additional needle to try out and see if it would help solve the ongoing problem. All he wanted in return was feedback on how the part worked and for me to let friends know about CVP. I rarely run into people like Ken in the general market place. He does good business. And all the CVP parts are made in the US. Thanks Ken.

’62 Triumph Rebuild Begins

I picked up this ’62 Triumph pre-unit chopper about three or four years ago. It came to me via the good karma express. If you want the long version (and my friends know that is always my preferred route!), go here: ’62 Triumph Find

I intended to restore it just as it sits and ride it down to Maryland to show the man that built it. I couldn’t wait to see the look on his face after having heard stories about how much fun he had building and riding this bike back in ’67. Sadly, I received an email from his wife on Friday that he had passed. I was very sad to hear the news and bummed that I couldn’t make good on my intentions.

A couple weeks before I’d already decided this would be the next project. After a fiendish rush of shop improvements over the last month, I’m ready.

We tore into it last night. Frank, Bill and Sergei helped me carry it down from the second floor via the stairs. It is heavier than it looks. We then went through the boxes and bins of parts to save everything that was metal and discard all the cracked acorns and shredded paper from the squirrels who’d made this their home for a while. Amazingly, it seems that every single piece to this bike is present. Many will need some serious cleanup and plating. I’m sure some of it will have to get chucked.

I don’t like choppers at all. But this one is just so damned cool I’m gonna have to leave it just like it is. Shitty steering and gallons of Bondo be damned.

After stripping the motor and back wheel from the frame we set about rubbing out the paint with compound, then hand glaze. I think it came out great. Paint stays.

Thanks everyone for your help last night. It was a good time. This bike’s story continues just like it began. . . with a group of friends working together and plenty of cold beer. Chet would be proud.

Mocked up the day I got it.

Big ole' mess in the back of my truck

Cleaned up nice, eh? Tasteful stripes too.

What is a Greasy Gringo?

I thought it would be easy to describe. And I guess if we were to be perfectly literal, it would be. But there’s something more. An underlying ethos so inseparable from identity as to be defining in itself. So pervasive as to be woven into the fabric of every fold of existence. The red thread in the dark wool suit only evident under close examination. Look closely and it’s everywhere. Pay no attention and it doesn’t exist.

Ever gone to dinner with your wife or girlfriend whilst your mind was a million miles away analyzing and solving a mechanical issue you’ve been working on?

Lain awake nights making step-by-step plans for what you’ll do next time you’re at the workshop until the alarm goes off?

Learned to participate in casual conversation while simultaneously working on something else in your mind, giving not a clue?

Attended a business meeting in a suit and tie with grease in your fingerprints that could not be scrubbed out?

Made detailed sketches of parts and specialty tools that you’d like to make in notebooks, napkins and scrap paper. Saved them in your wallet interminably until you improve the idea and eventually create them?

Taken calls from friends Saturday nights asking you to come out and you’re in the shop and tell them you can’t make it?

Stopped to help a broke down motorist on your way to an important event and taken the time to explain troubleshooting methodology to the barely interested as you fixed their car intuitively? While the rest of the people in your car roll their eyes, not understanding the sickness?

You get the idea.

This is no flash in the pan.

I’ve been suffering or benefiting, depending on one’s perspective, from this mindset since I was six years old and disassembled completely the first bicycle I’d ever gotten by 2pm on Christmas day. My parents, not being able to find me, finally made their way out to the garage to discover me elbow deep in parts and my dad’s tools. They threatened “You’d best have that back together by bedtime or you’ll never get another bike from us again”. I was dismissive, and confident that I’d have it done in time, even then. Of course a few unnecessary parts remained when I was done. That’s no cutesy cover-up. They added nothing to the function of the machine. A few years later I figured out that a hacksaw could cut metal and whole new world opened up to me. I cut some sections out of a couple aluminum lawn chairs we had and made two foot long fork extensions to that same bike. I jammed them on the forks of the bright yellow Huffy and used existing holes in the tubes to bolt on the wheel. Sketchy as hell. And fun! The first couple ramp jumps (if you could see the dodgy crap we assembled as ramps in the neighborhood) proved that modification to be, let’s say, temporary at best. But it didn’t stop me.

Obsession. Useful if you can harness it. At the same time a detriment that can haunt you. Its kissing cousin, perfectionism, amplifies the effects. Perfection paralysis. I also call it Magnum Opus Syndrome. Know what it is? Ever have it? Only perfect is good enough. You can guess where that one might lead. Mostly towards more thinking than doing. But these same traits can also bring meaningful innovation and gainful employment. Everyone’s got something reckon with. I consider myself lucky to have been saddled with these.

Drum Brake Redux

For one reason or another I am always fixing the crappiest, clapped out parts, Partly because I’ve sold all the good ones or I’m broke when it comes to buying motorcycle parts and have the tools to fix them. This drum brake hub was no different. The rim and spokes went to the scrap yard.

Chucked in the lathe ready to take a cut on the braking surface.

 

Close up of the severe rusting

Any time I have a wheel apart like this I like to resurface the drum because there is no other way to do it. This particular hub is made of aluminum with a cast iron ring pressed into it for the shoes to ride on. Years of sitting have severely rusted the cast iron part and corroded the aluminum. After taking about .020 off the surface it was looking like something useable again and a  final cut made it workable again.

After the cuts and cleaning

Spent the next few hours polishing and painting the hub before lacing it to a new SUN rim. There is a lot of info on building wheels on the net but the one I prefer is by a guy named “Sheldon Wheels Brown” He builds bicycle wheels but his info is superior to all else. Find him here. A few things to watch out for, Motorcycle wheels often have different length spokes and cross patterns in the same wheel. Meaning you can have up to 4 different spokes per wheel. This wheels spokes were the same length but the inners and outers had different lengths from the elbow to the butt end. You should try building your own wheels some time it’s fun and easy.

Looking fine

Happy New Year!

RD motor build

Went down to the shop on christmas day eve for some motor building fun. I have been collecting the parts and I needed over the last few weeks. Here it is to enjoy

Cases back and bare from getting the "treatment"

Trans in and endplays checked and set

Clutch side

Bearings on crank and seals installed

All together now

Oil pump rebuild

In the FACTORY YAMAHA manual there is a section about the autolube oil injection system. In this section it tells you how to adjust the pump stroke and remove and install it. It also says the pump is a precision machined part and is unserviceable and if needed it should be replaced with a new pump. Well that was 40 years ago and the NOS pump supply has dried up.  As you can see there are no less than 40 parts in this small pump. its about 2 inches square in size.

Heres the workings

I forgot to bring my camera to take some pictures so we are reeling on the diagrams. I ordered a new seal kit fromlast week and it arrived yesterday. Kit comes with 3 oil seals 2 pump gaskets and some new screws. Theres not much info I have found about rebuilding these pumps on the interwebs.

all the many parts

I worked on this thing for a solid 4 hours and had it apart and together at least 15 times before I had it working where I was happy with it.

setting the stroke

Last thing to do is bench test it with some oil and set the pump stroke for Idle conditions. Sorry again for the lack of pics today.
