Impressive lineup to say the least. Always thought one would grace my collection, but it hasn't happened.....yet. Funny thing happened when I first started watching the video...call me crazy but I could smell the Honda showroom where I bought my first CB 1972. :!:

I love my 77 supersport but my oldest brother thought I was nuts for choosing a sohc Honda 750. He was already in college when they first came out in 69 and he claimed you couldn't take them past 6k rpm or else the cam chain would come apart and rip the engine block in 2. I though he was nuts because right around 5k to 6k rpm is when mine starts to really turn on in fact when I took it to the drag strip a couple years ago I blew a shift so bad the tach went well past 10 rpm, it floated the valves alright but cam chain was still intact and I never read any mention of it on the 750 site I go to either so I asked the question about it on the site. I guess the early ones actually were notorious for throwing cam chains but I guess Honda addressed that issue early on because it's pretty much unheard of now unless the bike has been severely abused.

I'm conflicted. On the one hand, I own a '72 CB750K that, while in pieces, has a lot of potential. On the other, I don't want to get too attached, because I'm probably going to sell it to fund other hobbies.

I'll take a look at the vid once I get off work, though. Should be interesting.
1997 Valkyrie- Light Cutomization, but Too Busy Riding
1980 KZ1300- Bike's Haunted
1976 GL1000 (Yellow)- It Runs (Poorly) and Doesn't Leak (Mostly)
1974 Velosolex 3800- Better Than Walking
1972 CB750- Broke the Chain And Ate the Motor
1969 CT90- The Most Fun You Can Have on 90ccs.
1965 CA77 Dream- Needs a Full Teardown, but Complete

All advice I give is only valid until an expert corrects me.

By accident I ended up with the first cb750 sold here, my favorite shop owner built it and the second one (he still owns), from the crate. They are 4,000 serial numbers apart and the other one I ride is another 4,000 numbers higher so it may be the third one sold here. We know all the owners of mine, the Grandson of the first owner asked recently to purchase it if I ever sell.

I'm a big fan of the 750F, one I believe is my old one sold well at Mecum in Vegas. I did the double front discs, I scalloped a front tire practicing panic stops. That GL is sweet too.

The biggest issue that has been preventing me from purchasing a more modern bike for my wife and I to tour with is the fact that in order to do so would mean I'd probably have to sell my 77 750F to scrape up enough money to buy one. That is a big problem because I like my 750 a bunch and don't want to sell it.

I think the early bikes were more well known for throwing the drive chain through the case. There was even a recall on it. The battery overflow dumped acid on the chain, they changed three things and punched the engine case with 3 dots to show the recalls had been done. They even made a guide to help get the drive chain out of the engine case when it broke. Results are mixed on that one.
I agree on the modern bike issue and I can buy these, pay cash and spend as I go on them. My wife complained about the 750's once. I mentioned I could be a new Harley guy with a payment book and depreciation. Instead I'm building value into my old bikes. Keeps me out of the bars and She likes riding on the gl1000 even more than riding the 69 750. I built a lowered K0 for her to try this spring. drag bike seat, dropped forks and lowering blocks, 836 kit, cam and a Yoshi header. OK, it's for me to take to the drag strip. Don't tell her.

Thanks Wingnut, that article answered a question I had on valve guide honing. No one on the sohc4 site could tell me that a 6mm hone is used after the .259 reamer on a 750 valve guide. I'm going to bookmark that one.
