Having trouble searching/finding for this info. I am going to add some heated gear to my list of electronics and can't find out how much extra alternator power is available.
Anyone got a good link or the info?

I did see that somewhere a couple of years ago before I did my mods. I can't remember where, sorry. Without mods (RR wiring, RR upgrade) there wasn't much available for heated gear, especially if you had other electrical accessories, which is why I did the mods.
Cheers, Richard

Is this the kit?
Triumph T2500676 Harness
and FH020AA Package deal.
How much trouble was it to install, and what does it buy me? I thought the stator was the big issue.

i've heard of stators needing to be changed, but it hasn't been an issue for any p-twin owners i know. the r/r is pretty common.
i got the one where you do all the cutting and making the connections yourself. it was really easy, but then, i'm pretty used to this kinda stuff. the old one's harness had to be cut to get it off the bike because of how it routed through the frame and engine mounts. i also got the mounting bracket. it's been about a year and my memory's pretty shot, but i think the bracket mounts where the old one did and and the new one to that. the two units have different mounting holes. you could probably utilize one of the original holes and drill/tap a new one, but i just sprung for the bracket. it's snug, but pretty secure.

I can do it I just don't have time these days. If it can be purchased as a plug and play kit with the bracket, I will. Otherwise, I 'll take it to a friends and let him do it.  I will have this upgrade done very shortly either way though.
Does anyone know for sure if the kit he sells is a drop in as far as wiring goes? Not too worried about the mounting.

I replaced my rectifier once and found out, should have done stator also.Stator went bad next.
Got a new stator and a rectifier with 3 foot wire. Move it to ftont of bike below oil cooler, It was getting to hot in area in front of rear wheel.
Friend who is a mechanic suggested that alot of riders who have problems. Put where it can get better cooling.
Aot of mfg. put rect, in wierd places and the get to hot and go bad.

That's the one. Back when I did mine before Roadstercycle offered the wiring harness and I made mine up from Eastern Beaver. That Triumph harness looks like our plugs so should be a plug and play. 3' should be plenty long enough - shouldn't need the extended harness. You will have to make a mounting plate because the bolt holes don't line up with ours - but the mounting plate is dead simple - just a flat piece of metal with three bolt holes. Two holes the same as the existing mount and one for the new RR bolt hole that DOESN'T line up with the stock bolt hole. I mounted my RR east/west instead of north/south like the stock RR so that my cables plug in on the side nearest the battery.
Cheers, Richard

27 amps or 324 watts. I can run with driving lights on and a heated vest plugged in without overloading the system.

So, just to clarity, the recommended solution is to install the upgraded RR AND modify the wiring? I'm also having problems with my charging system and ordered the upgrade kit, but want to know if I should also plan on modifying the wiring when it shows up.

The wire is the real deal. I'd do that if only one choice had I.

What Moe said. Wiring is the first step. If you already got the upgrade RR you definitely want the upgraded wiring to go with it - it's usually part of the package from Roadster Cycles anyway.

Got the kit. I see now that the heavy duty wiring is included. Having to add on the circuit breaker and battery connection myself, so not quite plug & play, but pretty close.

Did this mod last summer after years of charging issues, you will not be disappointed
One thing I recall was having to fab a bracket to mount the RR as the holes are not an exact fit. I used a nice thick piece of aluminum, easy to cut and stays relatively cool.

Yeah, I sprang for the mounting plate from Roadster. Got her all wired up tonight and I noticed the difference as soon as she fired up. Big thanks to everyone who helped me figure this one out.

They have a mounting bracket? I don't recall that, or I was too cheap to splurge 
Glad to hear you got r done

I added the separate wire from the R/R to the battery several years ago with positive results, but with my Gerbings heated jacket liner, pant liners and gloves running at a high power level, it is possible to exceed the alternator's available output and discharge (ask me how I know) the battery. At 80 mph (my interstate crusing speed), the engine is using a higher percentage of the available power for the ignition system in relation to the max (around 3000 or so RPMs)alternator output. Therefore, the faster you rev the engine (using more ignition current) above the rpms that the alternator maxes out, you actually have less available power for accessories. Early BAs/Speedys like my '02 suffer more than later ones that came with an upgraded stator. So far, I have not sprung for the later stator. Our beloved bikes don't have much charging power for stuff. Heated clothing for two up riding would surely kill your battery. I have just learned to deal with it. Add the wattages of the headlight, taillight and ignition system, then subtract from the max available alternator wattage posted earlier in this thread and you have the power available to recharge the battery from starting loads and to power your accessories. When the battery voltage drops below the ignition system's minimum threshold, the bike will cut off, even while you are riding at speed.

I just bought the super kit from roadster cycles and for the life of me I am having the most difficult time mounting and connecting the damn adapter. I find that my stock airbox is in the way of feeding the cables through or the fit of adapter is so snug that I cannot get to the plugs. This is driving me insane can someone offer me some guidance so I can get this done.
Ride hard, ride fast, see the road in front of you and never worry about what is behind, unless you are checking on your buddy.

I seem to recall (but my memory is dodgy here) taking the battery mounting off allowed the cable to fit between the frame and the airbox. This is coming in the gap from the side so you don't have to feed any plugs through the tiny gap. Apologies in advance if this is a bum steer.
Cheers, Richard

I guess I'm a little confused. Exactly what does this upgrade do for our bikes?
'06 America, Raask foot controls, the bike use to be Graphite and Silver, now its Red and Black.

bruce, it eliminates one weak point in all our systems, the stock r/r. they fail, and if you're lucky, it won't be 35 miles east of bakersfield at 3am.

Another confused reader... how does it help from an accessory perspective? I am also looking at some heated equipment (I have glove liners and considering a shirt), and figure that our bikes just don't have the juice (at least not according to the various calculations I've seen).
Thanks.

Because the stock regulator isn't as efficient at charging the battery as a MOSFET regulator and the wiring kit straight lines (shortens) the connections to the battery (which runs a longer route through the stock loom) and uses heavier gauge wire. All of which give greater charge to the battery and more amps to the system. You can get a significant improvement just straight lining the wiring from the stock regulator to the battery with heavier gauge wire and better connectors (don't forget a 30amp fuse).
Cheers, Richard
