Re: Alternator on oldwing
I don't know and can't definitively say because I have never ridden a bike without a rotor.
With questions like this... everyone of us has an idea and an opinion, but the ones backed up with actual numbers are
the only ones actually valid. Everything else is a guess.
I'd bet that there are some math geniuses out there with the talent to calculate the actual effects. (it ain't me)
This topic is especially interesting to me as I have been seriously weighing the pros and cons of removing all that stuff from
one of my race engines and trying to free up some h.p.

Re: Alternator on oldwing
Here are some internal photos of the stator/rotor install:
Can't use the engine with the rotor installed. You can use the engine with the stator removed.
I have the alt mod installed. The alternator is designed to turn clockwise as viewed from the front of the bike. I have read that there are alternators that turn in a counterclockwise rotation.
This is the finished install of the alt mod on my '85: These are the bracakets I made from 1" angle, lots of hack saw and file work, and had welded at a local welding shop: The crank pulley is from an early model Honda Prelude power steering pump. The alternator pulley can be changed as needed to get the ratio to your liking.
I started with a crank pulley spacer made up of three 1/8 inch thick washers and two small bearings that had a shft bore of 10 mm. I went to the local fastener store for a longer crank bolt. I have since replaced this spacer with a piece of aluminum round stock that I drilled out the centre to 10mm. Thinking it's approximately 1 1/8" long.
You can see the rotor bolt that you use to turn the engine. The bolt is turned clockwise, and the engine turns counterclockwise, or a slooking from the front of the negine - the rotor bolt turns counterclockwise, the engine turns clockwise.Can't use the engine with the rotor installed.

Re: Alternator on oldwing
That's an extensive and very details rich presentation of your work!
I reckon you may have meant to say this, though?
Can't use the starter motor without the rotor installed.

Re: Alternator on oldwing
This is the first time I have seen an external alternator on a GL1000 and while I find it interesting, to me it makes more sense just to fix the original if it goes bad. It looks like installing an external one would be just as hard as fixing the original. Plus, the external one distracts from the beautiful engine. It isn't that difficult to remove the engine and do the job correctly.

Re: Alternator on oldwing
I disagree. It is less work then pulling the engine by a long shot. And it is an upgrade to a charging system that is marginal at best, if you have any added accessories that draw power. And as you can see in my avatar, it blends into the design of the bike very well.

Re: Alternator on oldwing
Meant to say "can't use the engine without the rotor installed". See that you caught me on this - bit of a typing slip.

Re: Alternator on oldwing
Have a couple of pics that are from the 2017 IBR. A young fellow dressed up his GL1000 for the race. Did very well. It is a lovely piece of work:
I think this is from a thread on this forum."When writing the Story of your life, don't let anyone else hold the pen."

Re: Alternator on oldwing
That is a fine looking bike! The Alt setup looks very professional. Must have access to a machine shop looking at those brackets

Re: Alternator on oldwing
There are a few more pics showing CNC machining and such. If a person takes their time, can make a good looking install.

Re: Alternator on oldwing
The alternator rotor also functions as the engine's flywheel. On the CX family it is mounted on the crankshaft so this is more obvious.

Re: Alternator on oldwing
An alternator doesn’t care which way it turns. It creates an alternating current that is converted to DC by the rectifier bridge which is not effected by direction of rotation.
