cbr 600 f3 regulator?

[skatefreak]

Evening folks.
Well, the battery on the 600 is well and trully fubar.
Will get about 4 starts on it between charging it from the wall which apparently only takes an hour these days lol.

But yes, so battery fubar, thought I would check the regulator as a matter of course what with it being a honda and low and behold, getting about 12.5 @ idle and 13.5 @ 5,000 rpm.

New reg I suspect but was reading a while ago that a GSXR 1000 model of some sort (cant remember which exactly though) is a more reliable option.

Is the regulator buggered and will putting a new battery on there bugger the new one as well?
Would a GSXR1000 'Insert model' regulator be a more reliable alternative to a second hand honda one?

Any thoughts would be much appreciated.

Best regards

If you're looking at a new rectifier, the OEM ones for CBRs are notoriously horrible - I've had two blow on the two CBRs I've owned.

R1 rectifier is the better option. Shindengen one.

Sounds like your battery is gone, I had the same on my CBR, will start a handful of times, but if not started for around two days, won't start at all.

On a few Honda's I had I would have one in with my tools as I knew they will go at some point and I was right.

I have seen people post how to make your own but I'm not up to that.

Found this,
May well be worth printing out for anyone with a hondddaaaa

I'm assuming 13.5 @ 5,000 rpm is the very lower limit, I will follow this flow chart and see what it suggests

PS, the lights get a lot brighter as the engine RPM drops to idle which is the same symptoms my NSR shows when the rec blows so I'm pretty sure its the reg/rec...
Any suggestions as to a more durable replacement? My NSR is on its 2/3'rd in 4 years (and yes, I've checked/changed the stator and checked most other components in that time lol)

PPS, something that may be symptomatic, the bike doesnt like to idle below 1,500, cut out on me a couple of times so have put the idle up to 2,000 and seems happy...

PPS, is the NSR and CBR 600 f3 reg interchangable?
The plug/wires both look exactly the same, resistance between pins as well...
May just try my nsr reg (known good) to trouble shoot?

I got one from germany on ebay as it was recommended to me on the hornet forum, no issues so far through the winter, the previous owner stuck a cbr125 reg/rec on which was tiny and was dead

luckily it didn't do any major electrical damage apart from a melted brake switch which I promptly replaced.

Will see if I can find the ebay link when I get home, came with a new connector block and pins which it happened I needed as the existing block was charred to fook

my last one was from germany also and so far has lasted longer than the last two.
seemed to be going through one a year until the last one.

Robby suggested one in another thread that should last i'll see if i can find it.

Edit: Mosfet Reg / Rec

IF you end up having to replace the reg/rec (which you will at some point even if it's not faulty now) as I said above, get an R1 rectifier (Shindengen FH012AA / FH012AB / FH020AA) and you'll save yourself some grief down the line.

Since replacing the standard GSXR one with an FH012AA MOSFET rectifier, it has been spot on. The rectifier doesn't even get hot like the OEM one.

Well,
Put a new battery on it and had another look today.
The battery has needed charging after using it a couple of times a day.
Today I had another look with a multi meter and it's looking more like the reg being the problem.
@ idle - 12.5v
@ 2,500rpm - 12.8v
@ 5,000rpm - 13.4v

Ebay only yields FH012AA kits from the US.
Could anyone give me a link to a regulator that would be compatible from an R1 or something?

Best regards.

Does anyone know if this will fit the CBR600 f3?
Its a pattern part for the GSXR1000, am just concerned that the connector may not fit.
