I bought a 1972 Honda CB 750 brand new in 1972. I had it for 4 years. It was a beautiful machine. It was flawless and would take me anywhere. I enjoyed it so much; the memories will be with me forever. Sold it and bought a new Gold Wing. Honda motorcycles were so dependable and if you took care of them, you would be rewarded with almost all your money back when you sold them. I will remember the memories forever. I wish I had my 750 today. I received so many compliments...they belong to Mr. Honda. Thank you to him.
I'm new here and before I read some of the comments I assumed that the astounding aount of meticulous attention to detail that you are giving this glorious '71 CB750 was your personal motorcycle. Then I noticed one comment says it is for one of your clients. What a fortunate they are to have connected with your shop. I spotted a 1981 CB750 for $1,500 that hasn'trun for 8-10 years and seeing whatyou are doing makes me think twice. You are an awesome machinist. Good on you.
Very kind, thanks. Yes, this is a customer's bike. An 81? Yea, unless you've got some sort of connection to it, like it was like the one you rode on your first date or something, find what you really want to work on and buy that. Cheers.
Enjoy your videos. I am glad you made a stand agains A-holes. Keep up your entertaining and helpful videos. Great job.Bike running probably better than new.
Nah, I don't. Thanks. I was hesitant to even mention it, because I think video creators that talk about that regularly, are sort-of whining about it. I will only mention it that one time. Cheers.
Well, it does have gear driven cams, so.... (ala VFR)... He's working on that ECU issue right now which I'm sure you have seen if you follow him, I'm not sure how he's gonna solve that rotary intake secondary deal with the ECU he has that apparently needs to be flashed and the company that made it, doesn't have any old timers left who know how. Net-sum, he's way, way past me regarding how big his brain is. Cheers and thanks.
I say again, constructive commentary always welcome because, I don't know everything. But I do know when to say no. Same customer is interested in a CBX1000 he's toying with purchasing, asked if I'd work on that, I respectfully declined. The CBX requires someone with very specific knowledge, of which I do not have. Cheers.
Love the machining stuff! You have awesome skills for that stuff, the minute detail is incredible. I don't even notice anything as far as camera stuff, looks great already! Ps. PLEASE wear pants when riding, when I see somebody riding in shorts I get the heebyjeebies😮😮😮 I Know how much it hurts. Quick ride on a dirt bike when I was 12, I learned fast.
Yea, I know. And I do wear full gear when I'm going fast, this wasn't fast, trust me. I was sticking around the neighborhood. But being it's 95 degrees with a heat index of around 103, it is what it is. If I go on the Concours 14, I am fully geared up, because... well, let's just say I engage the hyperdrive way too often. Cheers.
Well, it was at the beginning of what became a really fun time in Japanese motorcycle development. I remember the time very well, the horsepower battles and the marques cranking out a new model in response to one released by the other. During which, they refined everything over time. Cheers.
Hi, I have a CB750 K1 which has a bad idle but run perfectly on the road. This is mainly on carb/cylinder 1 I did not catch why you have been machining a part for the top of the carb. You explained that it could generate a vacuum leak. Was it the case? I have been following your two videos and I was amazed that you solved idle problem with 45 pilot jets. I have been reading a lot on this matter and never seem something outside of 40 pilot jets. Your videos are very interesting and detailled. Many thanks.
OK, first on the top set deal, I have no idea if those replacement "guides" or grommets (more like a guide, now) did anything. The vacuum thing was a guess, a hypothesis, more than anything. I failed to mention that I was even more concerned about dirt and crud getting down in there. It was on my mind, I may have edited it out trying to trim the video down; the answer would be probably not. On the jetting, it's extremely puzzling. I even checked the airbox, twice. First, the original time I pulled it and then, much later in the job, took it off again, checked the sealing gasket between the halves, checked the intake ducts, etc. They're not perfect, but there isn't any gaping holes or cracks. It'd need a pretty substantial opening or space for extra air to come into the airbox to create that situation where I needed to bump the pilot jets up a step. From what I've read, it's usually downward, where guys put smaller ones in. There are absolutely zero vacuum leaks from the typical spots, I checked with brake clean while running. Valves spot-on, compression good, fuel is new, etc. The only thing I can think of that might be is the fact that the exhaust, in my opinion, is louder than what I'd expect it to be. I'm not that familiar with stock CB750's, but even with the baffles installed, maybe somebody gutted the exhaust internals at some point? I'm spit-balling here. I don't know. Or, could the engine have been tinkered with internally at some point, like somebody popped in some performance cams or something? I seriously doubt that, but again, I'm just guessing or brainstorming here. Net sum, I do not know. It runs really well now, so I'm not gonna screw with it any more to prove a theory. lol. Cheers.
I learned early on, machine tools are a necessity working on antique or vintage stuff. But, I do make a lot of things that probably aren't 100% necessary, however, are an improvement (maybe) over what was there. Cheers.

We loved our 1978 CB750. I wish we'd never sold it.
Enjoy your videos. I am glad you made a stand agains A-holes. Keep up your entertaining and helpful videos. Great job.Bike running probably better than new.
Great job on that beautiful bike. Trolls are everywhere, don't let them get under your skin Buddy!
Nah, I don't. Thanks. I was hesitant to even mention it, because I think video creators that talk about that regularly, are sort-of whining about it. I will only mention it that one time. Cheers.
Tom, very nice work. What more can I say. Enjoyed the video and RIDE SAFE OUT THERE!
Allen Millyard called me, he said he needs your help with the Nemesis nightmare. Great content! Looking forward to the new camera setup.
Well, it does have gear driven cams, so.... (ala VFR)... He's working on that ECU issue right now which I'm sure you have seen if you follow him, I'm not sure how he's gonna solve that rotary intake secondary deal with the ECU he has that apparently needs to be flashed and the company that made it, doesn't have any old timers left who know how.

Tom yet another excellent video👍 thanks for sharing. The way you made stuff fit is impressive
Thanks 👍
Love the sound. I think I really want one
The bike sounds great, I'm sure the customer will be very happy. Nice job.
Awesome machining and problem solving you can work on my bikes anyday.🤙
That says a lot, very kind, thanks.
You may not know everything but you come REAL close. Idiots are everywhere, especially online. Please carry on !

great vids man kudos on the work
Nice Honda almost NOS great job done😎👍
Now, that's the way to say it's not absolutely original. Almost NOS. lol.. I'm going to borrow that from you if it's ok. Cheers.
A+
Set up right the SOHC CB750 is a velvet hammer........but with a little too much vibration compared to contemporary bikes.
Well, it was at the beginning of what became a really fun time in Japanese motorcycle development. I remember the time very well, the horsepower battles and the marques cranking out a new model in response to one released by the other. During which, they refined everything over time. Cheers.
" You did the best that you can do" if more people followed that mantra.

@@MotoRestoFL Many thanks for your answer.
The float bowl drain screws on my CB750 have a little rubber o-ring type thing. No sealing washer is needed. Does the parts book say to use a washer?
Yep. Crush washer.
You make me wanna go out, at 71 and buy a lathe. What you do is way beyond. Come on..........
