Let's see your CB750

[XMark]

My 82 C with Hondaline outfit. Bought non-running last summer. Cleaned carbs, replaced wires and plugs. Replaced fuel lines, filter, cleaned tank and rebuilt petcock. Timing checked. Runs but not well. Rebuilt forks. New tire on the back. Doing valves and bodywork this winter.

Yes I plan to do that but I guess I have to post 5 or six times before I can start a dedicated post. Thanks for the heads up about the other forum.

I forgot about that rule. Pics always make good posts and that looks like an otherwise super nice bike.

Old school cool!

Here's mine today
Seat is now fitted, busy connecting up the wiring inside the headlamp, hope there's room for the headlight when I'm done!

Ok guys, let's see your CB750s! My project Honda CB750 isn't much to look at, but I'll start.

Travis keep the faith, that particular shade of sh*t brown seems to have been popular in the US? Check out my poop brown US 1970 K0 imported here to UK before and after. Only 14,000 miles on the clock and from the state of the engine Id say correct, story goes the owner stripped the sump plug and oil filter threads on the last service and it sat for 45 years, very possible as who can strip the rear wheel spindle!.Sweet engine pulls 125mph.

The replacement tank I bought for my '79 Ltd bike was a shade of poop brown.

I rode it like that for a whole summer before I got it fixed. Actually just got it running again yesterday.

I'm really starting to like this era of the CB. Almost picked up an abandoned early 900F a while back. Guy didn't follow thru on the title so I let it go.

back in 2010 as i was working on a friends Harley in his garage and guy came up to me and asked if i work on motorcycles and if so would i like to buy one for $50.00
at the time i was saving up for a ride and asked where it was.
he told me his dad passed away and he was cleaning out his garage knew there was a motorcycle in it and saw me and asked.
i paid him the 50.00 and we walked to the first garage and we both dug it out and got it to my friends garage with 2 more tires for the front anf 2 for the rear and saddle bags and trunk and cowling.
it was held up in a milk crake.
it was a 1977 Honda CB750K with omly 1200 miles on her and a custom paint job.
8 days and 8hrs each day and a cost of $1000.00 i had a ride.
while finishing her I received a call from my adopted mom son telling me she passed away 1 week before I was to visit her in new york.
and so she has had her name ever since. "EDITH"
still have her and work on her every now and then.

Recently acquired a new one.. a K6 in Burnt Orange (I think it's called). The K2 is happy with the new companion
The K6 needs some TLC, it has been parked for a few years, but is cleaning up OK.. Other than the engine, which has been (badly) painted black previously, and flaking now. Really not sure whether to spend a bunch of time on it and get the black off (I'd prefer that) or just touch the black and put up with it..

 

[pickleknuckles]

Last ride of the year. Put 140mi on the K4 the other day.

Nice looking bike.
I have a few questions.
How does that shift mechanism work?
Did you have to remove the chain guard to accommodate the chain? It took several hours of modifying mine, but I finally got it to work.
What chain lube do you use?
With the bike standing perfectly vertical, what is the distance between the lowest point of the centerstand and the ground?

Thanks!

The shifter and brake work really well. It's a complete Tarozzi setup.

No, I just didn't put the chain guard back on. I restored it and even had it powder coated but decided not to use it for aesthetic reasons.
Its a DID VX3 530 x-ring chain and I'm using Maxima products (Cleaner, MPPL, and Chain Guard) to lube it. ...though I haven't touched it since I put it on at the beginning of the season.

Are you asking for a measurement between the ground and center stand when it is in the up position?
My bike is lowered a bit with custom Hagon rear shocks, and the trees lowered on the fork legs so any numbers will be specific to my setup.

Hi:
Thanks for getting back to me. And for sharing the information.
Yes, when the Centerstand is in the up position. Another way to measure could be: The distance between the closest to the chain part of the Centerstand (when it's up) and the chain, when the Shocks are fully extended.
Since I don't have the mufflers to rest the centerstand on (like it did with the stock mufflers) I use a steel bar to prevent the centerstand from hitting the chain. I'm trying to figure out if I've got the centerstand resting about the orriginal height from the ground. I actually have 2 1/2 inches longer Forks than stock. But that far back on the bike, it's raised a lot less.
I have a similar O-ring chain. It took a lot of work to widen the chain guard so that it wouldn't rub against the wider chain. It was complicated by the fatter 510 X 16 inch rear Rim And tire that is Laced to the rear hub.
Does your chain lube fling off the chain onto the bike at higher speeds without the chain guard to contain it?

Here's a list of the modifications that I've made on the bike.

I had the Valve Cover Chrome Plated (Required Engine Removal)
Installed Pull-Back Handlebars
Installed Crossover TT Pipes
Installed Kickstand Stop Bar To Set Kickstand Height
Painted Tank, Front Fender, And Side Covers With Silver-Mist Pearl Paint
Installed Oil Cooler

Installed A Shinko 10 SR712F 100X90X19" Tire On The Front Wheel
Welded A Larger, Thicker Plate On The Kickstand
Installed An O-Ring Chain
Installed LED Headlight, Signal Lights, And Taillight

I highly recommend going to an electronic Ignition, if you haven't yet. I installed mine in the mid 80s. I set it to the stock setting, then I advanced it 2 or 3 degrees until it idled the fastest and smoothest. I haven't had to adjust it since then.

Gotcha. Yeah, I can measure it at some point this week. My exhaust is the early no-no style from Yamiya and the center stand hits the rubber stopper in what I assume is the correct location, so while ground to stand wouldn't be stock, the chain to stand will be.

My bike already had a Dynatek ignition on it when I bought it in the early/mid '90s and I've never had to mess w it. Ever. It's been rock solid for the past 30+ years.

2002 Honda nighthawk CB750 on the final stage! Taken almost 2 years but I'm meticulous that way. Lol. Before and after pics. Just got a 1980 Honda CX500 custom I'll be starting soon. I'll post back process pics as well. Very nice bikes on here. Build your bikes my friends!

Nice old bikes! Unfortunately, there's still a long way to go until the season starts again. Now 50 cm of snow and minus 6 in Stockholm so a lot of time in the garage. My K2 was finished in 2023. Now winter project with a very bad K0. Wishing you all a happy new year! /Thomas
