Topic: CB400F charging system

[ttr400]

Just wondering does the CB550 Charging system put out more power than the CB400F system.

The reason I ask is would the 550 stator be an upgrade over the 400F system.

Thanks Kevin

i was comparing a 350 stator against a 500/550 one a while ago and i think they are the same,they test the same,fit into each others cover the same but the lead is different thats all,heres the thread.

Thanks Dave.  I must have missed that thread.
But yes also discovered that the 550 stator fits into the 400/350F cover.

Just wondering if it puts out more power..

The published specs for the two systems (400 and 550) are the same. 150W @ 5000RPM

Some published specs for the CB500 have it making 200 Watts.  I rather think that is a misprint.  But, I haven't tested that one for output.

Lloyd, do you have specs for the 350f?

I've not personally tested for maximum alternator output.  I'm just pleased when they recharge the battery and run the lights.   

Here are the specs, I'm able to glean from my many manuals:
