Welcome!

From the beginning? really? I look back sometimes and am amazed what we've covered. This bike has gone thru many iterations since i got it in 1974. Each was a relatively short term "build" as we say today. There were always shortcuts or things not quite according to plan.  Nothing wrong with that.

So many happy miles and years went by.

Now that I'm older and have other bikes to ride, and have a friend that keeps us on course, we are building this the way we want. If you're not at that point yet, don't feel bad about skipping this or that to get it done and get on the road. Riding is the main goal.

We do hope to get this done this decade. And besides riding it, I'll enter it in some local shows and such for fun. I'd like to take it to the dragstrip too.

So, today I found pieces to make a great fuel line adapter at ACE hardware. It'll be brass and should work fine.

While i was down sick, I wordked up 3 3 ring binders. 1 with the Honda parts book I use and Honda Servcice Bulletins. I filled one with receipts dating back to 1999 on this project. And the third is all the install sheets for the different parts I've bot, and articles and tip sheets and printouts from forums, etc. on assembling this critter.

No update this weekend, out of town on R&R.

Hey MC, if you're doing this bike totally stock and NOS, why not just buy NOS side covers?  They seem to be available everywhere for 750s and I'd hate to see you go with 37 yo side covers that are so delicate when you can have new, relatively flexible and durable ones.

Folks with 650s don't have that option; our side covers are unobtanium nos these days, so I want to live through you vicariously. ;)

Thanks for the ideas. I'm not committed to totally stock, so that's not an issue.  They are the original side covers, so that's one sentimental reason. I did review the offerings at eBay and the left side covers were either the wrong year with different shaped emblems,or they had a crack in them like mine where the first weld job is. That was a common area to crack. The one i did find that was worth having was going for nearly $100, as i would expect it would. A $40 repair is fair to me.  I'll Just need to be careful with my removal technique. I had just installed new rubber frame grommets and they were holding on real tight.

Motogrid.com has them at $80 to $107 but listed "unavailable".  There is an aftermarket supplier, but I've heard mixed reviews about fit and I don't think they have the emblem detents.

Yamiya has them as a set only for $300. They probably are actually new repros and hence "soft", but too pricey.  They also have finned aluminum ones for $450 a set. Way cool.

According to Owen, even a NOS side cover would be brittle unless it had been sealed in a bag, as its time, not exposure that ruins them. Time to outgas the polymers that keep them flexible.

650s are an interesting situation. I didn't even know they existed until i joined here.  :)

Carpy has metal side covers for $100. each. Steel stamping.

Lucky, why the hell do you keep dredging up 2+ year old posts. Also it seems you are completely oblivious to the fact that this forum is full of extremely knowledgeable people who obviously know a hell of a lot more than you give them credit for. Most everything is solved in days around here and its not surprising considering the massive knowledge base and the fact that we have the likes of Jay {ape engineering}, Mark {m3 racing} Mike Rieck  { head specialist extraordinare}, all Honda 750/4 experts from the 1970's through till now, and just about every CB750 expert on the planet are members here... Try and keep up to date man....

Came home from Pokagon State Park a day early. It was the wife's call and we had a good time. Homesick for her new kitty. So Bruce and I got to work this AM.

First mocked up the new cables. A bit of a problem here. And some clarification from the gallery. The speedo cable comes up from the right side but must cross to the left. Where does the cross take place? The way I've got it seems awful tight.



Then the tach cable they sent me is a good 3 inches too long, so it would loop way out. So that's got to go back.

The clutch cable fits awful tight, but that's my fault. I told them 3" shorter and probably would have been better off at 1.5" But it seems to work OK.

Then the A throttle cable also works OK, but it 1.5 in too short. I told them to go 4" shorter. Had to hook it up without the quickthrottle. Which leaves a open space on the end of the bar.  Still it will work for startup purposes. Pulls and snaps shut smoothly.



Luckily if I decide to have new ones made, Bruce pointed out, we can use the current ones on the next project which will have lower bars. Or I'm sure someone would buy them from me at a discount.

Bought a clutch cover from ebay for the purpose of getting the clutch lifter. Mine would probably be fine but has 75K miles on it with obvious wear marks. The newer eBay one comes off a bike the seller said has 7500 miles on it. It certainly looks like new. The adjuster slot doesn't have any marks on it at all, indicating the clutch may never have been adjusted!


So we took off the clutch cover for the third time to swap out the parts. Feels good to have them in there.

Looking at the coils, they really don't fit the brackets cleanly. So we opened up the flanges with the Dremel so the coils would lay flat. I ran with them in a tiny bind forever and ever. So this is just one of those unnecessary steps that no one will ever see, that makes me feel better about it. Put them together with stainless buttonheads, from ACE hardware.


So it goes.   :)

Also, earlier in the week, I think i solved my fuel line problem. ACE hardware had a nice selection of brass tube flange fittings. I got 2 pieces that will thread together, one end for each size hose. Pretty large internal passages, larger than i'd had run before. The clear is the larger size from the carbs. Then it reduces to the 5.5mm clear braid into the petcock.


The amount of brass that will actually show is about an inch. Should be flexible enough to make the bends necessary.

Another good shop morning:
During the week i talked with MotionPro about the cables. The tach cable they sent me is 27 inches long. (measuring the outer sheath and permanent endings, not the spinning nut). It sticks way out in front of the triple. The one I had been running was 24" long but its gray, so must be off a different model. I need to confirm the length of a black CB750 tach cable (center digits 449) so i can get MP to adjust this cable length. Johnnie tells me his K4 cable (449) is 24.25 long. Can anyone else confirm this so I have something to go to MP with?

The clutch cable was slightly shorter than I'd asked for but its 2 inches shorter than i need, same with the throttle. So my bad.   :(   I'll get new ones made and use these on the next project or sell them to a cafe builder.

Picked up some various chrome hardware bits from ACE, they're getting pretty used to seeing me.

Installed the coils with wires. Took a few tries to figure out the drill. Turns out the left coil is removed, the rt coil on the brackets with wires, then bolt the lft coil down.

Mocked up the APE Frame rail kit so we could see where the harness and throttles were going to run. All these parts look stockish, but each has a slight change and you never know how they might interfere. Ex: The Andrews Coils have the Ig wires dropping straight down, rather than straight forward like stock,  requiring 90° and 30° fittings.


Got all the left side wiring done and the tranny cover and sprocket cover on.


Bout ready to put the pipe on.

G'Day Ron, you might need to seal the threads on those brass fittings, just to guarantee that you won't have any leaks. I used the same fittings to extend the hoses on a tank I had so I could remove the tank and place it on a stand and synch my carbs, and it weeped gas all over my hot engine. Cheers, Terry. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Teflon tape should be fine for sealing the threads; Does gas react with teflon tape?

Worst case...make the joint permanent by fluxing both threaded portions and then wicking solder into the joint once you've heated up really well.

Yeah, I had the same thoughts about Teflon tape, and I think I'd solder them. Cheers, Terry. ;D

In another thread there was a discussion of using Teflon tape on a bolt that was plugging an errant hole in a case on a 550. Seems the white plumbers tape, while having a high enough temp tolerance, 550° F, (that doesn't matter in the fuel issue, but it mattered in the other thread as it was being used on an engine part) the white stuff may not tolerate petroleum products. Too bad as i have a drawer full of the white rolls. Seems every plumbing project I do, and i do several each year on rental houses, comes with a roll of white Teflon tape.

So on that thread we discovered there are different colors of TT. The yellow tolerates petroleum products. So I'll probably just get a roll of that. If it leaks I've got all winter to solder it.

The threads are of the tapered variety and truth be, the white would probably do it.

MC, beware of using the white Teflon tape in gasoline systems. The benzene in gasoline does not directly effect the Teflon polymer, but it does tend to slowly dissolve the bonding agent in the tape. The end result is a white goo substance and a possible leak. The yellow Teflon tape is for natural/propane gas systems, not for gasoline. A much better and safe choice for a thread sealant is Permatex Aviation Form-A-Gasket Sealant Liquid, Permatex part #80019 as it won’t break down when exposed to gasoline.

+1 on the Permatex.  I tried using both the white & yellow TT on the bolt that secures my oil filter adapter, leaked eventually both times.  Was given some of the Permatex, no seepage, problem solved.

You know, one of things I like about this forum is that with all the collective experience available, there's no longer any need to fcuk something up in isolation. I think of some of the problems I had on my early "pre-internet" builds that left me scratching my head and wasting money on products that just didn't fix the problem, that I just don't have any more due to the input of members here who've had the same problems and found a fix. It sure does make building bikes a less daunting task! Cheers, Terry. ;D
