Good example, but we are talking about outboards here of the vintage the OP is having issues with. Are you a Honda motorcycle fan as well? My better half and I both ride Honda Valkyrie motorcycles. She grew up on nothing but Honda bikes.

You meant to add, of course ... provided that the key switch was still turned to 'ON' ...
You have a good point there!
I remember one time we were pushing a guys car around to try to catch it in gear to start it, it wouldn't start until someone asked him if he had the ignition key turned to on, he forgot that part! #-o :P

The engine ran.
This same engine is made in a rope start, tiller operated configuration. No battery required on that engine and the same ignition system.

The charging system on that engine is totally separate from the ignition system. The charging system has zero to do with ignition.
I gave you the explanation on how the system works in a short version. Read it again. Needs no battery to run.

My first bike was a 1971 Honda CB175. I rode my current bike off the showroom floor one year after I got my discharge (1981). It runs as good today as it did then. No one else has put a wrench to it other than me since the warranty expired. I even gave it it's current paint job myself, but I paid someone else to powder coat the frame and some other misc parts while I had it disassembled.

Yea, it's off topic but it keeps his thread active while we wait to hear back from him. LoL Nice looking bike. Sportster if I'm not mistaken. When I bought my 81, my girlfriend (and future ex wife) had a 1980 "bowling pin" sportster as we called it. I think it was the last year that AMF owned and built harleys.

Jmichael - what model is that in the photo?

My turn......

Lesa on her Vstar 1100 Custom. Nice and comfy ride but low horsepower and buzzed the handlebars above 70-75mph.
Her 1994 Honda Magna V4 would blow it away and not break a sweat doing it. Would also keep up with the Valkyrie pretty well.

Hey Pappy, any truth to this? Never try and start a FITCH or E-Tech outboard with a low battery. It can damage the ECU.

Pappy, that is my 1981 KZ 1000 LTD (K1). I've installed some Kuryakyn grips and different mirrors since that picture was taken, but other than that, it still looks the same. I like the styling of those Valkyrie. Looks like a nice bike for taking long trips.

You would need to know what year the motor is and research whether it has electronic fuel injection or other computer controlled functions. If it's just a carburetor/ magneto motor the battery condition will not affect the running performance. A dead cell in the battery will likewise not affect it. As long as the battery is grounded and can accept the current from the charging circuit, running the motor will not damage it (the fact that the motor was started proves it had a complete circuit).

My guess is you have carb problems unless this is a later model motor with a DC stator type electronic ignition. In that case your problem is that your charging circuit is likely malfunctioning. Once the engine is running the stator should generate more than enough energy to power the ignition unless it is not working correctly.

I had a IMHO very knowledgeable older Gentleman that works in management at a local BRP dealership tell me this.
