I did a test of my charging system and found a short in one of the phases of my alternator, checking the 3 yellow leads to ground to see if there is continuity. So I ordered a new one and put it in today.

You must begin by removing the left side plastic, then remove the antifreeze overflow bottle. This gives you access to the stator cover.

There are (8) 8mm bolts that need to be removed

Once you remove the bolts the stator cover might be sealed on rather tightly with the gasket, I had to tap it with a rubber mallet to get it loose. Here you can see my deep fried old stator. Make sure to have an oil pan under the bike to catch what oil drips down.

I removed the rear plastic and disconnected the alternator wires from the Regulator Rectifier harness, and threaded the wires loose and removed the stator cover and all.

There are 4 star bolts that need to be removed and a 5mm bolt that holds the wire harness in place with a bracket. I am not sure the size I had an assortment of star bits and found the right size. It is larger than a 120 but smaller than a 130 and it has deeper stars than most star bolts.

Tighten ALL the bolts back up 9ft/lbs is the torque setting, inside and outside bolts.

I had some gasket remover, but still had to scrape the toughest parts off with a blade. That old gasket was really baked on. Make sure you replace the gaskets.

Here is the new gasket seated by the dowels, you can see the flywheel and the magnet. Hardly any oil came out, I had my oil-pan underneath to catch what fell.

I threaded the new wires back the same way as the old ones PITA!! its really tight in there. And used some dielectric grease on the connectors to prevent corrosion.

I also replaced the fan switch on the left side radiator, it was not working.

It just screws on, a small amount of fluid came out but not much

I also removed my shock plates and replaced them as well, they had grooves in the side where grime had cut away at the alluminum.

Here is why I stopped using PJ1 that stuff makes a mess! I cleaned that up too with WD40 a rag and a lot of elbow grease.

Hey, great writeup Miguel. Hope I never need it, but maybe....

Did you go with the OEM or Electrex stator? ???

I pack a spare R/R under my seat. So far, so good..... :cool:

Still on the original battery, FYI.

13.45v most of the time, while riding, with hi-beams on.

12.70v after sitting and resting for a day or 2. (key off)

:idea:

I wonder if the "new and improved" stator for the '02 models would fit the previous generation VFRs?

If it has more windings then the '98-'01 version, it would put out more juice. Good for folks who run 'lectric vests and grip heaters.

Hmmmm.......

Too bad one couldn't see them side by side and make a comparison.

I think I'll poll the "big list" and see if anyone knows......

OEM Honda Stator,  Now I am peaking at 14.5v at 5000rpm.  My battery would be charged at 11.7 volts static before.  Now its 13.1v headlights are much brighter too.

From the manual the VTEC stator and the 5th gen alternators are rated at the same wattage, I dont know what the new one is rated at.  It must be a bit more.  470watts

Which OEM stator? Ayers fiche shows two available: 31120-MBG-003 and 31120-MBG-D01. How to choose?
