Bad condenser

Does it have a clutch lever switch that prevents starting the bike without pulling the clutch? And does that switch need cleaned/replaced? Or the contacts of that switch.

Maby u need a multi tool for these little test rides

The last time I walked my motorcycle, I was stopped by the police.

20 secs of actual content stretched over a time wasting 15+min.

Gremlins!!

Still think if not coils, ignition switch and kill switch might be the culprit.

Check for a bad fuse holder or a bad connection at ignition switch

Check the coils?

Back to basics . Charge the Battery , and do a Load Test . Check Battery connections have not corroded , With Instructions from the manual , or the Web , check your charging system . Check coils output , and wiring at both ends . Is there a battery cutoff switch that is failing . . I had similar , start to give it a bit of throttle , and it would cut out , ride steady no problem . One Day I decided to go through everything , put a spanner on the Battery Negative terminal , one hand holding the cable , and the cable came away with the bolt still in the Terminal , what had happened , was the ring terminal had slit , and , when giving it throttle , the vibration caused the two pieces to separate , shut the throttle , vibrations ceased , terminals went back together , engine run O.K .

it’s a strange one i think it’s not gas at all it’s electric ⚡️

I have one and the gears get jammed, are they hard to repair?

Bad earth and battery,coils,points, condensor? Great bike and an awesome video again Eric.

Eric what kind of ignition system does it have? I mean points or CDI.

Love the kz750's....thanks

It’s not running on all the cylinders

That`s one way to save gas!

I bought a new one in 1979. It was a great bike

Oh man, I hope you have recovered alright, pushing that old barge in that heat, not for the faint of heart Eric. It needs a complete tear down of the electrics, and the fuel system before you try to take it for another run.

Cracked main fuse?

Battery and voltage regulator...

the red light is comming and going while u drive....

Is that the twin or the four cylinder ?

Shit happens.......... Dud battery that. Also regulator/rectifer.

What is the red light at the bottom of the instruments? It kept coming on at low revs

Pulse Generators/Coils? If it was on old fashioned Points I would renew the Condensers.

Sounds like fuel starvation, coupled with possibly a charging problem, z750 dont sound like twins (unless it is actually a z750 twin - they did make one), camera sound may not be what you are hearing, but on camera it sounds like it only runs on 2 when it is running, just had a similar problem on my V65 Magna, so I know that sound and feeling. No idea on your electrics, condenser?

Should have gone home as soon as you got it running the first time.

I had 50 yr old kz. The seat pan would collapse slightly grounding out on battery poles . The bike would die just like that

Coil shorting out when it gets warm?

arnold schwarzenegger is The Terminator, Eric is The Turbonator

Coil?

Sounds like Missing a cylinder and Battery is shot and I don't think that bike will run on a total loss of Batt. power! I know How My pool feels on a hot day enjoy, I hope you took out your wallet LOL LOL!

Try to fix a bike first before driving.

Hey great video. Was interesting going on the "diagnostic journey" with you. It definitely sounds like its cutting out fuel then once it sits the bowls fill back up, but also an obvious charging issue as well. Just from my own experience I've had issues with slightly pinched lines and even those cheap inline filters and low amounts of gas. It's just enough of a restriction and not enough weight of the fuel to make it to the carbs as it's running. Let it sit for a minute, then fires back up. Keep up the good work man, it's great seeing the channel grow. Side note: I just saw you got merch! Ordering a shirt 👍😁

I was mistaken for thinking it was a twin. Sounds like the Kawi twin I had, check your coils and the CV slide rubbers.

Sounds like it's only on 2 cylinders as well as the electrical issues, besides a battery issue , might be worth looking at the side stand/clutch cut out switch .

I just bit the bullet and order a Voltage Regulator / Rectifier from common-motors last night. Love that vendor. My wish list there is a long one. In the mean time, Im working on the electrical this weekend. Hope I have better luck... Lol

What about the 750 Kawasaki?

"I'm just getting further from home". Much respect for your tenacity!

I know that pool had to feel good.

I could only hear one cylinder working. Seemed like the other was along for the walk. I would be testing or replacing the coils with something used you have around the shop.

I laughed big when you went into the pool. I tried to think of what might be wrong but every time my idea seemed to be a dead end. Bummer

You bench press motorcycles!

When you get back home charge the battery to full charge and see if it runs any different and check the charging.

Sounds like it's missing on one cylinder or the charging system isn't putting out!

That's gotta be a steam bath even in the shade.

Eric, do you ever stop for a rest? Seems not, which is good for us watching in. Thanks for posting.👍

Quite an informative video 👍 I'm dealing with a similar motorcycle engine ( 2 stroke). The motorcycle was in storage outdoors for 5 years. Now, while revamping it, found the engine seized. Upon opening the head found severe corrosion deposits hardened on the cylinder wall. Moisture could have made its way via exhaust and maybe head gasket. I am soaking the piston and cylinder wall with diesel, WD-40 and 2T oil. After a week, the build-up seems to be loosening and fragmenting... Still a long way to go before I can see the piston moving... Is this good enough? Thanks

Just replace the Brake light / Ign. Switch assembly also. I dropped that teeny tiny spring in the Hi/Low beam switch!!! I could not find it. Next day I pushed a big magnet around the floor and got it!! Huzzah. It was tricky putting all back together.
