FZRSupport: the FZROnline Archive

Hey all, I just wanted to chime in and say for posterity that I installed a MOSFET regulator in my FZR after going through 2 new replacements which failed quickly. The MOSFET along with a good to-engine ground (12 gauge) and a to-battery positive (12 gauge) *directly* from the regulator output resul...

Ok yeah just to be clear the R6 type are also listed as stock for later model years; get that kind of regulator, not the smaller 4 pin kind.

I would suggest getting one of those connectors from Don linked above + stock regulator for a plug and play replacement.

And from my experience...buy a regulator from a place that will take returns. You may be buying a 15+ year old product...

One that claimed to be stock from ebay. I connected the regulator directly to the positive of the battery which helped but then measured the voltage drop and it was .5 volts being lost from the regulator to the battery just due to using too small of a wire. I'm gonna get a mosfet and solder plugs on...

Also keep in mind that you probably could wire up many 5 wire regulators. The three white wires are universal AC from the stator, the black is ground, the red is positive. I actually just burned up another one and am gonna try a mostfet... Also I recommend wiring the negative terminal from the regul...

I took it for a 45 minute test and it was basically pegged at 14.2 the whole way. Looks good to me all though I will be going through it much more. Don thanks a lot for your help, if you pm me a paypal I can send a small thank you.

It'll be done but I'm crazy busy so I'm hoping to delay a month or so. I will keep putting the effort into this bike but I'd like to use it as a semi-daily while working on it.

Am I ok to ride it for the time being with a voltage meter? I know you will wash your hands of an assessment of any risk inherent in your advise but I'm just looking for context...reliability is questionable at this point until I wire up a new harness myself? 18 year old harness, I agree...But I'm n...

I have seen a bit of corrosion = resistance = voltage drop = melt wires before, let me tell you :P I am now using a brand new battery to eliminate variables (luckily these things are plentiful for me :P) Here's my question now: ok, second new regulator: according to this flowchart https://www.electr...

Ok well this last one peaked at 13.05 volts at idle and dropped as I revved. On the last one I didn't see 17 volts for more than a few seconds before I shut it down...but this current regulator already got quite warm in less than a minute. Seems too fast... Yeah I think something is shorting, but ba...

It's a 1996. there is an extra ground wire coming from the stator side of the plug that is supposed to attach like a washer to a bolt....i attached this direcly to the voltage regulator bolt that goes through the body.

Just left for work agai, I can upload pics in 4-5 hours... it's this one http://www.ebay.com/itm/261312407704?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 5 pins like stock. Also I will be testing with a different battery today; i am not totally familiar with all the failure modes of this lead...

Update:
The second new regulator did the same thing as my original. I think it's a wiring/other issue. Could it be my stator?

So this second new regulator puts out 13 volts at idle and drops into the 12's on revving.

I used the stock wiring harness plug directly. The black wire is grounded to the negative terminal and frame. How do you say cheapie in Chinese? :mrgreen: I have some old Ducati one that I might wire up...the shipping wait is agonizing but I don't want to risk running it as total loss if there are a...

Hi all, I'm am extremely happy to say that after a 6 year haitus, I'm back on a motorcycle. I bought an FZR with 37K miles, great feeling engine and transmission. Super cheap. The guy who had it said that it developed a stutter at high rpms when he was riding it daily. I noticed (I work at a motorcy...
