The refreshing of a Big Red Pig by a guy with no clue.



Well, my new to me BRP is making a mechanic out of me! It was operational when I bought it, but since this was going to be the bike that I finally wanted to learn how to really work on motorcycles with (not just oil changes) I started to tear into it after it stalled on me a couple times. Now there are pieces of it spread all across one of my garage bays.

First things first, drain the who knows how old gas and clean the filter/petcock. It has a Clarke tank on it and I got to learn about how those tanks don’t have a way for the gas to get from the left side to the right….well, unless you can pop a wheelie (I can’t) or you don’t mind putting it on its side. I like having a bigger tank, but I must say it’s an interesting design choice. At least it looks better than the Acerbis. There were some small blueish white crystals on the filter and settled at the bottom near the petcock, so tearing it all apart was worth it for cleaning purposes.

The next tasks were to rebuild the carb, do a valve adjustment and give it an oil change. The carb is currently in pieces waiting for parts (rebuild kit, air cut off valve and replacements for stripped screws), so that’s in a holding pattern. I was able to disassemble and then verify that I had the right jets, needle and clip position using this YouTube video while taking into consideration the mods on my bike. The valve job was my first attempt ever at one, but I’m fairly positive I got it right on my 3rd try (TDC verified with the stator cover off, all rockers loose, .008 exhaust / .006 intake). Finally, the oil change will have to wait until I can start it again.

So, that brings me to electrical. This is what I started with:



I thought about fixing it, but then the ghost of my electrical engineer step-dad visited me and told me to do it right, so I ripped all of this off the front of the bike and ordered a brand new Baja Designs dual sport kit (this one didn’t even support an H4 bulb). I also ditched the $9.99 special heated grips and disassembled the chopped up wiring that leads back to the KTM radiator fan. When I had the stator cover off I was able to verify that it has a Ricky stator installed, but until I get the new Baja Designs kit I won’t be totally sure if the owner before the last owner actually wired everything back to the Honda wiring harness correctly, or if additional re-wiring will be required (which will be 100% new territory for me).

And this recap leads me to my first (of probably many) questions for the forum. I need DC power to run my fan and I’m sure I’ll need it in the future when I get around to installing heated grips and a power port for a GPS. It’s my understanding that I’ll need to wire up a rectifier/regulator to two of the wires (green/white) from my stator to power things like my fan. I’m looking at the diagram from the Ricky stator website and it has a battery coming off the rectifier/regulator. Do I really need any sort of battery if I’m powering accessories off of a rectifier/regulator? And probably another dumb question; if I need a battery... for example this one...I only see two leads, so is the red/black wires coming off the rectifier/regulator and my wiring going to my accessories connecting to the same leads? I'm assuming yes, but I don't understand how that prevents surges (man I wish my step-dad was still around...).



More story-telling and pictures to follow as this noob mechanic gets his hands dirty and hopefully gets his bike running again without having to take it to a shop! My supermoto wheel kit and carb parts arrive tomorrow, Trail Tech rectifier/regulator on Thursday, Baja Designs kit on Friday and my RSW Racing fork brace should be here next week.

Anything on the output of the regulator/rectifier should be ~12v DC.

If you were just using a regulator it would be ~12v AC. The rectifier is a full bridge rectifier that flips the negative swing of the AC to a positive swing. So you get bumps of +12v, then there is typically a smoothing cap and the battery to make the bumps a smooth +12v DC.

When I did mine a few years ago, I removed the original windings that were on a few poles and replaced them with windings that used every pole on the stator. I used larger wire and coated it lightly with epoxy. I think I have enough left on the roll I bought to wind another.

I'm pretty sure this is what I did (this quote is from THIS PAGE ):

Quote:
Hey,
Removing the stock lighting coil is CAKE. Just start pulling and unwrapping and it will come off with the wire. Clean the poles for any excess epoxy.

Those much smarter than I already figured out that the secret formula is in the # of winds. Over ten poles, you want 32-34 turns per pole, totalling 320-340 turns. Approximate output with 18 awg is ~125W, approx output with 16 awg is ~200W+.

I did the 16awg wind on mine ~340 turns total over 10 poles. I was scared so I upgraded the stock wiring that goes up to my BD reg/rec to 16 awg also. It was a TIGHT fit in the rubber grommet that fits in between the cases but I made it happen.

I have dually 55W headlights that both run all the time (110W), they are wired in series with the two yellow wires on my BD reg/rec. In other words, my headlights run on regulated AC voltage, so they run when the bike runs only. Everything else in my BD DSK works just as usual on DC voltage from the battery.

I would say the results are EXCELLENT, my dually 55's are like 98% bright at idle, and my battery is fine and the reg/rec never gets hot.
I ran a Trail Tech regulator/rectifier and ran everything on 12vdc instead of AC.

I also ran the Tusk wiring kit (comes with all LED tail lights and signal lights), and ran a BD headlight assembly with an LED headlight bulb installed. It worked awesome.

I think you'll want a battery unless you don't mind your lights going dim at idle. Something like the Trail Tech, but it is just 10 NiMH AA cells. You can buy those at Costco for $20 and put together your own pack. That is what I did.

After actually reading your entire original post, it seems your problem with the original setup is in the wiring.

-that regulator in the pic looks just like the Trail Tech reg/rec I had. Ordering another may not net anything. It is obvious it already had a DC circuit.
-I used an actual SLA battery, the smallest one Batteries Plus had on the shelf. Those look like NiCads, which dont last long on a bike. Batteries DO act as a filter in a 12vdc system, and thats a good thing.
-your original Ricky Stator should be fine. I'm willing to bet it wasnt wired right.
-I would eliminate any 12vac circuit and run it all DC, making sure you float the ground on the charge circuit. With LED bulbs, you NEED dc voltage and there is no advantage to running ac like there was in the past.

Hi, All!

Thank you for the feedback. I finally found a USA wiring diagram for the xr650r and that answered a lot of my questions regarding the condition of the OEM harness. Indeed, it was not all running where it should have been (or not connected at all). There was also signs of heat/burning due to corrosion, so I eliminated those connections and soldered/heat wrapped them instead.

I got myself a battery...went the lazy/expensive route and got a Trail Tech one to go along with the rectifier I ordered. I was totally looking at those SLA batteries from Batteries Plus, so now I'm kinda kicking myself, but oh well. I'm going to keep it a mixture of AC/DC right now until I get the Baja Designs kit (which is designed for the OEM wiring scheme) but I might switch it all over to DC once I get the kit in my hands and see what I'm dealing with. In the meantime, I started creating individual fused wiring looms for each of my accessories (Vapor gauge/fan/charger) to make it easier to isolate problems.

The last of my carb parts arrived today, so tonight I get to re-assemble that and put it back on the bike. I also should get my brace today or tomorrow, so I'll put that on while I'm installing these...



I'm starting to feel better about things and more confident that I'll be able to get it fully functional without taking it to someone. Thanks again for the advice and examples from your own projects!
