1970 Honda CB

CB750-1027703

Rebuilt, Rebuildable & Reconstructed

1970 CB750 K0. Engine #CB750E-10277119; frame #CB750-1027703 I have no title for the bike... I am required to complete the title field in the ad, but there will be no title provided with the bike. Bike has a PA Special Plate under the seat indicating it is "RECON". I examined the bike and found no evidence of frame damage, though I am no expert on these bikes. See photos. It handled normally during a brief test ride. The bike was stored for the last 30+ years in an unheated, but dry storage garage. It was not running when I purchased it, but it now runs and drives. THE BROWN TANK SHOWN IN THE PHOTOS IS NOT INCLUDED IN THE SALE OF THE BIKE. IT WAS ONLY USED TO GET THE BIKE RUNNING. INCLUDED WITH THE SALE OF THE BIKE IS THE BLACK "DRAGON" TANK THAT IS SHOWN IN THE PHOTOS. The black tank has some fuel residue in it. I did not fill it with gas to test for leaks, though it appears to have little rust, and I see no evidence of rust holes or fuel leakage. I wasn't sure what was in the tank, and didn't want to contaminate the carbs with whatever is in the gas tank, so I used a clean tank that I have in my parts stash. The brown tank will be listed separately. The bike starts with the electric and kick start, runs and shifts through all gears normally. Clutch action is normal, and the transmission doesn't jump out of any gears. I rode the bike up to 30mph on a short test ride. Front and rear brakes work. There are no abnormal engine noises... no valve tick or knocking or piston slap. Some cam chain noise, but seems normal... no chain slapping sounds. Some smoke on startup, but clears once it has warmed up a bit. Some interesting period aftermarket parts included with the bike: HOOKER HEADERS AND MUFFLER; HENRY ABE CAST ALUMINUM WHEELS, POSSIBLE BARNETT CLUTCH, HELLA H4 HEADLIGHT The bike was not running when I bought it. I cleaned the carbs and bench synchronized them. carbs look to be in good condition internally. Cylinder #1 carb leaks. It probably needs a new needle valve and seat... brass float has no fluid inside and no pinholes. None of the other carbs leak fuel. I cleaned and statically set the breaker points so that the bike would start and run. Prior to starting the bike, I drained the oil tank and sump, flushed the oil tank with kerosene to remove sludge, and removed the oil filter housing to clean it. I refilled the oil tank with oil, then ran the starter with the plugs out to get the oil system primed. I did not remove the sump plate or replace the oil filter. I did not run the bike much, but the buyer will probably want to do a full fluid, filter and sump screen cleaning, as this bike probably has sludge buildup due to sitting for so long. The bike had a bad wiring harness. I replaced the harness with a used CB750 K1 harness that is unaltered and known to be sound. This K1 harness was pulled off of a running K1 that was being restored due to the fact the black sheathing or housing was cracked and brittle, but wiring is sound... no chafing on wires. I did not modify the main harness when I installed it, besides wrapping the cracked sheathing with electrical tape to prevent chafing to the wires. I had to add bullet terminals to the headlight leads and the horn and high/low beam wires from the switches so that I could plug into the main harness without alteration, as these wires had been cut previously. All electrical functions including gauges work, with the exception of turn signals, which were removed by previous owner. Original terminals are there on the switch leads and main harness, as well as the flasher, so should easy to hook up signals. Other mechanical issues... possible helicoil in #2 cylinder or stripped. #2 plug threads in easily and doesn't feel like it is cross threaded. It will bottom out, but doesn't snug up. Plug #2 backs out of the hole normally. All other sparkplugs are normal. Carb #1 leaks as previously mentioned. There is damage to right side cylinder head fins from a tipover/crash... see photo. No airbox. No centerstand. Some parts chrome plated and plating is peeling. The bike is running, but obviously needs additional parts and labor to be roadworthy. I am selling as is, and have done my best to explain flaws that I know of, as well as give an accurate depiction of the bike in the photos.

On Mar-02-14 at 08:18:07 PST, seller added the following information: To clarify to the many who have asked questions as well as "informed" me of what this bike is or isn't... it is definitely not a sandcast CB750. Sandcast refers to the engines that had parts that were literally cast in sand molds. These are the early 1969 CB750 KO. This bike does not fall into that time period of production in 1969. However, what I have is a 1970 K0. This K0 has many parts in common with the 1969 Sandcast K0s, and these parts were only common to 1969 through early 1970 K0. Later 1970 production bikes were the CB750 K1. Parts on this bike common only to K0 models (sandcast or not) include top triple tree, oil tank, seat and probably other items. Side panels are gone on mine, but those are also K0 only items if they were there. By using the word "sandcast", I'm merely trying to point out that this bike could be useful to someone that needs parts for a sandcast, or that has a general interest in the early CB750s. The unintended result is that I have aroused suspicion that I am trying to dupe someone into bidding on my misleading them to believe it is a sandcast bike. This was not my intention, but I suppose there are those naïve enough to part with a minimum of $1800 in a keystroke or two without knowing much about vintage bikes. Hope this additional information clarifies what this bike is or isn't. People have also asked "what is the VIN?" I listed the frame # and engine #. However, the bike as a recon plate... I don't know what the DMV would consider the VIN, if one were to register a bike with a recon plate, and I have no title for the bike for reference. The original VIN is useful in identifying the model of the bike, which is 1970 CB750 K0. Note that my bike has "non-matching" frame and engine #s. That is the way Honda built bikes in the 1960s and 1970s... the numbers were "non-matching" from the factory. Here is a great source of information on this subject: http://www.hondachopper.com/engine/engine_timeline/timeline.html I gave a description of the bike that is accurate and honest, and posted a lot of photos, and have now given you additional information that I hope you find useful in making a decision on whether or not to bid on this bike.
