Generator output??
« on: October 06, 2018, 10:11:56 PM »
Hello.
After reading comments on here regarding the weaknesses in the Cb750k charging system regarding headlight build wattages.
I'm wondering if there is any difference in output between the early K models & the F models?
I ask this because I used to use 100w/65w H4 bulbs in my old F1 without any charging problems. I did a lot of night riding at that time as the bike was my only transport.
Your comments would be appreciated.
Sean.

I wonder why the Auto needed different genny.
Did they have a larger output?
Was it the same fitment as the others?
Would fitting the Auto genny to the other models be a worthwhile upgrade?

The field coil in the CB750K is rated at 190watt (less 19w running) net power 171watt. As  the CB750A f/coil is rated at 250watt (less 40w running) net power 210watts.
They are interchangeable, not sure why Honda fitted a higher wattage coil in the CB750A...increased battery size?

Increased battery size and no kickstart backup.

They DO have a kickstart, but it lives under the seat.
If it's got tits or wheels, it's hassle, if it's got both, RUN!!!

Probably doesn't rev so freely either being automatic...
So doesn't get the higher voltages so often....Just a thought

I stand corrected then, and doffs his hat to the gent in the corner.
