I'm not sure you could call it a build yet. this thread has so far been used for information gathering. Which I am extremely grateful to you guys for bearing with me. One more week though and I will have this old bruiser in several pieces.

I am currently hunting around for a detailed/accurate guide on dual disc. I probably wont have time while I am home to do this, but would like more stopping power. I cant tell if its the type of brakes on the bike or if I have some sort of malfunction but its kind of terrifying slowing down in a hurry from high speeds.

I guess ebay is killing off motorcycle salvage yards, as the two I knew about growing up in Midland are gone. The closest one is three hours away. If they respond to my parts request we might be picking up the parts for the dual disc on my way home.

Anyway, back to studying. I have to be able to explain the impact of the united nations high commission on refugees in the morning. very exciting.

Anti - where is that closest salvage yard? There was one in SA until recently, think it shut down.

By the way, there is a guy on eBay in San Marcos that sells a lot of CB parts:

And someone in Austin:

I know of one in seguin. I can pm you his info if you want. He isnt online and I dont know if he would want me posting his phone number in the open. He has quite a bit of parts for all types of 70s bikes. He has a 73ish cb750 he restored to show room quality that is very sharp.

I will send the guys you posted a pm. I am looking for the parts I listed and also am interested in a 77/8 F tank. Seems the cheapest way to get a longer boxier tank.

The one that is three hours away is in abilene. its about half way in between austin and midland, so three hours from both here and where I will be for the rest of the month.

There also is a MC boneyard in Belton (60 miles north of Austin) right next to the Stillhouse Hollow Reservoir dam. It specializes in vintage bikes. If anyone needs an email address for Pete, the owner, pm me and I'll provide it.

Got the bike to midland. Skins all dried out. Not used to the desert anymore. Getting a game plan worked out. hopefully have the seat made wednesday, bike has to stay together until then to get it to the metal shop for measuring and fitting.

I should have picked up tires before I left. There are only two bike shops here and they are the big places that dont really have good prices. I cant seem to find a place that has bt45 TT in stock online. tried dennis kirk, bike bandit, motorcycle superstore, etc.

Anyone order tires recently?

plan on doing some buffing and figuring out how to flush brakes, clean the garage, organize tools.

apparently this is what nearly everyone does. Noobtastic. I think I am getting pirelli sport demon. BT45s are backup plan.

I dont have a picture right now, but spent today getting old paint off the engine and polishing. I am using a cheapo drill kit from HF. It came with a white bar of polish and a red one. So far just used white. I dont think its possible to really clean this bike without disassembling it and doing each piece. might take a power washer to it, delicately. hopefully wednesday seat. cant do any of the other planned things until its on.

Yes, that is what I will do [haven't mounted 'em yet].

What are you doing in Midland??

Mine and my girlfriends family are from midland. So I am taking the opportunity to use her parents garage that they dont use. Only downside is all the dust out here. Not sure how painting is going to go.

got the mockup of the seat made. I thought we were going to have to cut the frame, but the test fit was pretty comfortable as it is. had to lose the helmet hooks though. My dad cut them off, smooth as butter.


now the cowl sits pretty close to the existing brace. This also lets me keep the grab bar. LED lights arent in yet, I thought Dime City was a good price, but the price was per LED light. They better be really nice at almost $60 for four. I thought I could pick up a 3in LED brake light at the truck stop or autozone, but no dice. I doubt it will get here in time now. might have to extend my time at home.

Sunday we're going to get the seat made out of higher gauge metal, 22, and hopefully knock out the fork seals and steering bearings.

About to order the tires. I polished some of the engine as well, but no pics.

I'm pretty sure you know...the higher the guage number, the thinner the metal.

Good progress!

brain malfunction. I did know that. The gauge were actually going to be using is so thick I cant cut it myself with the shears or the giant table press. I am pretty frail though. Ill post some pics of the machines in the shop. The newest one is from 76. I am pretty sure the spot welder is older than my dad.

Soooo, we got the front end disassembled. I was expecting some rust under the fork ears, but what we found was disheartening to say the least. No money for new tubes right now. But they are on the wishlist.

not a good pic


this is how we had to leave her


I plan on making a pedestrian slicer while my dad is working on the seat. seems easy enough.


you can kind of tell how some of my amateur polishing went.

still a ways to go

and heres one of my nephew and the new puppy he got for christmas



tomorrow we are reassembling everything and installing the new seals and all balls bearings. Tonight, I have to derust the tubes some and then fill in the largest of the pits and burrs with jbweld and sand them smooth. There is a link somewhere around here and it seemed to work for that guy. One of the tubes has a fairly large pit and the fluid was grey and smelled horrible. apparently the fork ears had filled with water at some point and so rust on them is pretty terrible. I will get some pics in a while when I go to clean and sand them. I am probably going to paint the uppers of the tubes black to hide the major pits. Going to use the universal fork ears to replace the old ones.

the seat and handlebars should be finished this week as well. We got clubmans and I have some flatter bars that we will swap if I dont like the feel. new pirelli tires should be here by thursday.

slightly disappointed with the tubes, but it seems like it will work out.

You see what I ran into with the rusty tubes.  The polishing takes practice and you can always go at it again later.  I run Pirelli's on my 800lb'der and I have been pleased with them.  What's funny is Bridgestones are horrid on my 800lb'der but seem to work out ok on these bikes. People in the forum for that bike can't get them off fast enough.  Must be a weight thing.

Ive read a few reviews for the pirelli sport touring and they're all equivalent to the bt45s. They seem to be a little stickier and so dont last quite as long.

The polishing is kind of fun to see a difference. I got most of the paint off the sides of the engine I plan on getting it off the front when I go to change the oil.

I cant find it, but I read a how to on how to cover up the top of the tubes. They sell a chrome pipe cover at home depot for covering up pvc. It slides snugly over the tubes in between the trees. I cant find the link, should have bookmarked it, but it will look a lot better than mine. there are some pretty serious pits on these.

Theyre soaking in evaporust right now. Mostly to see how well the chemical works. I think I am going to spray them with rustoleum and then go get that pipe cover in the morning.

Here is what those sleeves look like on the bike. I think it pulls it off pretty well. Looks nicer than just the rustoleum covering up all the pits. I like the new ears too. Took some banging on them to get them to go over the sleeves I made.


and this is the seat as it will be. I wanted it to go lower and cover more of the frame, but beggars cant be choosers. My dad made it up during the day when he had down time at work.


A few hiccups. We didnt have anything to measure the ATF for the forks. and I turned the key to see if I had any power, none. I assume the headlight just hanging there for two days pulled wires loose. No idea which ones it might be. But it looks like thats what Ill be doing tomorrow.

My dad doesnt think he will have time to do the handlebars with me. I might just get the holes drilled and then try it myself, or just run them outside the bars.

Waiting on tires, turn signals, and integrated brake light. hopefully theyre here by friday, have to go to el paso to see my stepdad and all next week my dad will be out of town on business.

Tomorrow I am going to try to see if I can spray my practice tank with the paint gun. Never done that before.

Slightly disappointed, thought more would be done by now. I need a damn garage at home. I guess at this point is just to get everything wired up and roadworthy so I can take it home.

At least you got some things done.  That cafe seat looks a little on the thin side.  Wonder if a cover will help.

The metal is pretty thick, so hopefully thats enough. I wanted it to extend down the sides more to cover the frame, but I wasnt there today when he put the pieces together. Too late at this point. I am thinking about getting some other kind of rubber to replace what was on the frame for the last seat. That might lower it a half inch or so. Cant really say, it may have just been sitting on there weird. we were mostly focusing on how to get the whole front end together.

It was actually much more simple than I imagined to get it it all apart and back together. heres hoping nothing comes loose at high speeds.
