Need your help Hondamatic 750 owners

[birdmannn101]

Finally got this 76 CB750A with a 78 wire harness and 78 indicator running after cleaning the carbs. I asked earlier if the rear wheel spun in Neutral and some people said, "Yes." It starts in Neutral with the side kickstand down. Wheel spins and can't be stopped with your foot. Apply gas and the wheel spins faster (like it might be in "L" gear). Raise side stand and pull shift lever up and it goes into "L" and the wheel stops. Add throttle and wheel stays stationary. Pull shift lever up again and it goes into "H" gear, wheels starts spinning and will go faster if you add throttle. Drop the side stand and it goes back to Neutral and wheel keeps spinning.

I wouldn't worry about what the bike dies while on the center stand. If you are stopped and put it in neutral, does the bike try to move forward on its own? If not, leave it.

Considering that Tools owns about half the A bikes in the world, he does not seem to be concerned about it either. I think you should be ok.

While not autos, my 78 does this and so does my 06 yamaha.

Well, I just took it for a test drive and it drives great in Neutral and "H"  In "L" it doesn't go anywhere.  So, what your saying is to drive it in either Neutral or "H?"  The bike creeps forward in Neutral.

If yours does the same thing I won't worry about it and just drive it.

Thanks for getting back to me,

NOW you have an issue. if the bike tries to go forward in neutral or will outright go, then something is messed up.

My guess is that there is something with the neutral indicator switch and that the tranny is fine. the light is turning on at the wrong time.

[TOOLS1]

 I do not know how the shifting mechanism could be so messed up that neutral and low could be switched. You know when the kickstand is put down the bike automatically goes into neutral. On the shift pattern, neutral is on the bottom, then up one to low, then up another to high.

When the kickstand is put down the bike automatically goes into neutral and starts creeping forward. If I open the throttle it moves right along.  My shift pattern while on the center stand - If I shift down it's neutral on the bottom (wheel spinning), one up to Low (wheel snaps to stationary and no movement), then up to High (wheel starts spinning again).

Do you think the guy who had it before me changed something to accommodate his handicapped side car?

If you were me ... where would you start looking?  Pull the torque converter cover off?

[TOOLS1]

Torque converter would have nothing to do with the gears so to say. It just drives the transmission. Also there is nothing inside the transmission that would prevent the wheel from spinning in gear, or even neutral. I cannot think of anything that would switch the gear pattern. Does the cover on the left side where the shifter is show any signs of being removed in the past? Does the bike not move when it is in the "Low" position?

Nope, the cover on the left side of the bike doesn't show any signs of tampering. 

No, the bike does not move when it is in "Low" position. 

I guess the side stand is okay since it puts the bike in neutral, turns on the neutral lamp and allows the starter to start the bike.  Maybe what I need to look at is how could the bike be started while still in gear?  Would the changing relay have anything to do with this?

[birdmannn101]

Okay, I have decided that this handicapped, wheelchair bound, sidecar driver has altered the transmission so that he does everything from the sidecar and doesn't need to reach anything on the left side of the bike while he is in the sidecar.  He has this rigged to "think" it is in Neutral with the neutral light so he can start the engine.  Actually, it is in LOW according to the engine and electrically in Neutral.  He also has it rigged this way so all he needs to do after starting the bike is to roll the throttle and away he goes.

Now, since he has passed away and I don't know who rigged this for him, I don't know how to bring it back to normal so I guess I'll just ride it this way.
