Very nice, at least you should be able to do some miles on that one, it looks like the interstate model with the big tank....

thanks, yeah the big tank is nice, I had a 750 commando back in the day and 100 miles on a tank was it.
Its a nice runner, needs TLC, no oil leaks or electrical problems................yet.
It came with lots of extra seals, gaskets and parts. Almost all stock, except Boyer ign, single carb.
I also have all of the repair paper work since bike was new.
The only bad thing is I had to give up one of my bikes ('76 CB750), financial and room.

Congrats! Looks super clean. How 'bout a ride report, how does it compare to your soon to be forgotten K6?!

that is a nice bike,the 74 850 was the best,yours is a 75 e start ,but I kind of liked the 750s.the single carb mikuni is one of the best mods for a driver,as is the boyer,the response is much better,you can also add an extra plain plate in the clutch which will give a nice light pull,steel tank?bill

I just drove to the bike home, a short distance. I'm going to take it down a frame down and repaint (not tank) and replace a few things. There are some issues, loose bolts here and there leaking forks, cracked tires are 15yrs old (date 0200). An old bike I really don't fell comfortable riding until I know what I got.
The guy I bought from didn't do any maintenance for the ten years he owned it, he hardly rode it. When i say no maintenance I mean no maintenance, never changed the oil or battery, or anything else.
So you ask what did the oil look like, well surprisingly good and and primary case oil was fine also. The orignal owner had a maintenance record.
Ill give a full report when completed.

Yeah the single carb they say is a nice setup. I wish it was a Mikuni but it has a square Ama,l like the one I had on my '76 Bultaco. Yes steel tank. 34mm new Mikuni can had for about $80, might go that route.

Nice...............I had a 750 Commando with the interstate tank. Shook like hell, but was nice at highway speeds

Yes they do shake until about 2K rpm.
My Norton buddy says the 750's were quicker handling than the 850, due to fork geometry. i haven't looked into it but I believe the fork angle was increased.

My friend is working on getting one back on the road tight now. I would recommend going through the transmission because they are notoriously designed and manufactured with a bunch of slop which causes failures- broken teeth and bent shafts. You can bend the shafts back a bit and there is a bushing kit available to tighten up the gearbox, which is highly recommended if you plan on putting any significant miles on the bike.

Thats true, my 70 commando had trans problems, I plan on looking at it. I believe the 850 had less problems, up-dates.

yes the 850s had a lot of upgrades,better swingarm,the 75 had adjustable isolastics,no shimming,the gearbox has some thicker gears too.80mph was criuzing speed on the highway on my 750 with 21 tooth front sprocket.only thing I did not like about 75 is all the extra gear for the electric assist as they were called,they also have a better head steady.steel tank is a good thing!bill

Your right Bill about all you mentioned, Im in a learning curve on the bike and I like it. Last eight years Ive been fixing up or restoring mostly Hondas, Its a nice change.
Ill tell you one thing Its easy to see why these Neanderthals didn't make it in the age of the evolving Japanese bikes.

A friend told me a few years ago that there's kit available to convert the shifter seal from an o ring to a lip seal. Might be worth it if that's a problem area.
