I drag raced air cooled VW's for many years. Lightened flywheels had a significant difference on a street driven race car. VW crankshafts are much heavier than a Honda crank. Surprised to hear it makes no difference on bike, but did in a car.

Not sure if VW cranks are counterweighted. I'm pretty sure the CB's cranks have huge counterweights.

The stock VW cranks were Not fully counter-weighted. They were statically balanced, but with out counter-weights would flex above 5K RPM, wiping out the main bearings, and/or the case and crank. From memory the 750 crank was as heavy, if not heavier than a stock VW crank. The VW flywheel, on the other hand, was MUCH heavier than a 750 rotor, with much of the mass located in a diameter 2-3 times larger.

Agreed. There are differences. Merely stating a fact that it had a significant effect on our street driven race cars, and our flywheels were NOT lightened by half, as this new CB rotor is. (and with so many people running pods, they already have an idle issue.) Sorry if the comment seemed to throw water on the excitement of a 32amp rotor. Not my intent!

For those who don't have EFI or heated grips,20amp is it enough to keep the electric start?

Have we discussed what affect the extra extra amps will do to our existing gauge of wiring on the rest of the bike?

I'm not versed on this like anders or TT but my take is that say for example a turn signal will only DRAW so much juice so it's wiring SHOULD be ok unless a short were to occur? But, what about the wiring from/to the alternator, rectifier, regulator, etc? Is the WHOLE system an on-demand thing only and will not fry existing wiring UNLESS there is a full 32amp demand? At what point in the system would the demand be distributed from? IE where would those 32amps go to as a single power source before being distributed throughout the bike to each demand? And would that part of the wiring also need to be upgraded? Sounds to me that this could require a possible solution.

Hi Jerry,
The three wires from the stator connect to the gray plug on the reg. the black plug connects to the battery there are no other wire. If you kick over the motor with the key off it will produce voltage. I hope this helps.

Now that I don't have to fiddle with the cover I am interested. I was looking into just having a stock unit rewound, this looks better.

I think Jerry really wants to know if the stock wiring harness is up to the upgraded charging system....

The stock system puts out around 17 amps and discharges at idle. The upgrade system produces voltage if the motor is turning key on or off.

I'm expecting around 14 volts at idle witch means higher voltage to the coils. Bike will run with a dead battery. Yes it sound be able to kick

start using a battery eliminator / capacitor will need to eb tested.

It doesn't in any way connect to the bikes wiring it connects to the BATTERY ONLY it will in no way do anything to bikes wiring.

Everybody should be running a separate relay with upgraded gauge to the coils anyway.

This system will work very well IMO. Truthfully ....a "slimmer" cover is just about achieving a look right? Cutting it down saves about 30 grams of weight (maybe). I mean....have any of you fellas dragged the alt cover lately.

Well as you know there are a lot of buggered covers around that were 750 dynocovers.. And they get buggered every time. It gets laid down on that side..We like modding our bikes and looking different.. A no lose situation.
And it can be batteryless.. Even better..

Jerry Rxman Griffin aka MuthaF'er · « **Reply #65 on:** February 10, 2013, 04:34:46 PM »

Well then I guess we need to see a picture of Anders girlfriend!?

Retro had my back on that. I was wondering where all that additional power would initially go and how would it get there ie larger wiring and to where. Heavier gauge wires to the battery so the extra juice doesn't melt them then the individual demand of the existing circuits being handling by it's existing wires. More demand therefore not handled by existing wiring but rather with new circuits thus protecting our precious unavailable wiring harness. Therefore a non-issue.

Cool, I got it

alternectomy?=the act of changing an alternators gender from electro magnetic field to permanent whilst upping the output.

I guess I've been away from the forum too long. I've got to keep an eye on this thread. I give a vote on a 500/550 kit.
