Re: For all you reg/rec experts...

You guys are making me laugh!

The track bike is a vfr400, and I have the idle set at about 1200 rpm. I'm crediting the high idle voltage to the fact that the bike doesn't pull current for the headlights....

Either way, I think it is fine.

Re: For all you reg/rec experts...

For the 9r they call for 1100 +-100 rpms.
I have bare essentials when comes to my electricals. So only headlight tail light and phone charger still 12.9 at 1k
I love my idle the way it is. Sounds like a beast. Kinda like its camed out lol
So ill live with it. I have thousands of miles issue free always chargeing and hasn't left me stranded hundreds miles from home. Lol
I wouldn't like it if mine was chargeing 14.5+ volts at idle.. just seems high in my opinion. But I'm no electrical engineer or anything so what do I know :-) but really

No sorry I was referring to vfr mans bikes idle.

Wasn't trying be "douche" blade, lol. Just got a migraine at the moment. Directed it towards wrong person.

Hope your reg holds up for ya Vfrman time will tell
thanks for shareing why ya did, may help others in future!
No worries :-)
But you need to raise the idle speed, 1000RPM is too low, and 12.9V is too low.

J/W blade did you set his idle for him? So you kno its at a stock idle adjustment? If not then I can wait for vfrman to reply thanks! Hence me asking him for his idle setting. Not hey blade whats his idle at?

The idle speed is totally relevant to the line of questions Iv asked! To the higher voltage at idle than normal.


Idle speed should not be that low, 1200RPM at least. If you are idling below that then it would explain why yours is barely charging.
I assumed you asked about my own track bike since you didn't specify whom you were asking.

Being at idle and already cranking out same voltage as what should be around 5k seems funny.. as long as reg will put up with it it'll be fine
we all know honda can't build one to withstand it lmao

Curious what your idle speed is at being a track bike.

I would want a minimum of 13.2V at idle, but 14V is better.
Idle is stock, why wouldn't it be? The engine doesn't drop under 7000rpm on the track so idle speed is irrelevant.
The engine is totally stock, but I don't run a charging system on the track.

Hope she holds up for ya! :-)

Keep us updated.

That's what it should be making, the battery still needs charging at idle.

Re: For all you reg/rec experts...

I tested the reg/rec today. 14.76 volts at idle and 14.83 at 5k rpm. I'm calling that a win.

Re: For all you reg/rec experts...

So have you tested it and get good volt numbers.

See its on a track bike. Lets us know how it holds up to the conditions

Re: For all you reg/rec experts...

OK. Got it all installed today...and after blowing the main fuse, all is good. FYI, blk/white is ground and blk/blue is +ve...oops.

So, here we go...Ideally I would like a better mounting place, but I'm thinking of making some vents in the track plastic allow some air in.









And with the tail on...




And here is the TINY stock unit in the stock location...

Re: For all you reg/rec experts...

Exactly. That 6th wire is to turn on the headlights on the Kawi. So I'll just ignore it.

Re: For all you reg/rec experts...

But isn't that for the kawi? And its going on the honda? So holds no relevance other than kawi is weird lol
Good to know for future reference tho, I didn't know they did that.

Let us no how the install goes. Should be easy. No fires should happen lol atleast I would hope not
