    MOSFET R/R unit. -SOLD-

    I recently upgraded my Roadstar to a Series type regulator. I had a MOSFET unit ready to go in, but decided to buy a Series unit for a great price. This left me with an extra regulator, and seeing that these things are pretty reliable, I don't have any reason to keep it. I tested it in my '85...

    1996 r/r running 18.08 volts at 2500rpm?

    Bike is 1985 and I just hardwired a 1998 r/r with a 30amp fuse to the battery. Ground went to the neg battery post. Followed RAWarriors thread to the "T" and even mounted in the same location where the old coils were. I get 12.62 when turned off but when I rev to 2500rpm I get 18.08? Sorry...

    R/R conection

    I had the motor out of my 85 and had the trans done. I am now putting it all back together. The three wire connector to R/R had been repaired but the plastic plug in connectors are gone. I had the wires marked for reassembly when I took it apart. Then my brothers kids were playing in the garage...

    R/R replacement.

    A couple years ago, I replaced a failed voltage regulator with a newer model, the one that has a dedicated ground wire. Both output wires now go directly to battery. I am getting good voltage (13.3 or so) at idle, and 14.4 at 2000 rpm measured at battery. I mistakenly thought this was a MOSFET...

    How do I wire up a 2008 R1 R/R? 3 wires + second connector..

    I heard of people swapping out the R/R for the R1 version.. I got the 2008 R1 R/R, but cant find and write ups on how to install it. I see it has 2 plugs- on the left plug it;s 3 wires of all the same color, and the other plug is a red and black wire. So adapting it to my 91' max', do I just...

    Newer Mofset R/R mounting on '85-'92 Vmax

    What did you do? Description and pictures if you have them. I've seen Ryan's mount under the seat where the coils used to be. Has anyone used a mounting plate and bolted it in the stock location?

    New style R/R!

    I just checked Amazon.com... There is one of the new style OEM units with the separate ground wire left there. About 64.00 with shipping... Just a heads up in case anyone wants one..

    burned up my R/R

    Well i cooked my R/R.... not sure if this is a normal way for these to go:ummm: I found a new one online for $40 so its not a big dent in my pocket book, but i just dont want this to happen again. Im curious if something else electrically could have caused this problem? Bike still runs fine...

    Can we use R/R from smaller engine bike?

    Hi I read somewhere that all R/R are the same. We can use any that sort of fits. But is it ok to use one from smaller engine say for example from an R6 or Ninja 6R? Or does it have to be coming from the approximately the same engine size with Vmax? Thanks. Regards,

    Is it safe to connect R/R directly to battery?

    Hi guys, need advice from vmax gurus here. One of the suggestion in fixing the hotstart or low voltage problem from this post http://vmaxforum.net/showthread.php?t=19108 is to connect the R/R positive directly to battery with a new bigger cable. But when I was reading the service manual...

    New R/R is in but....

    Usually my bike runs fine but sometimes it looses power and leaves me stranded. Will be cruising then I lose power, engine won't rev and eventually dies. Similar to running out of gas. At first I thought it was my fuel filter because I hadn't changed that yet, no luck. Then CaptianKyle and...

    R/R mod?

    Just wondering what years to do this mod for? I see alot of talk of the older vmax, are you guys referring to earlier year vmaxs or 1st gen period. Reason I ask is it was brought up that my plug wire arching could be from my r/r not putting out enough. So I checked it with a volt meter and this...

    Which R1 r/r

    Looking to replace my r/r with an upgrade. I have checked out my options and it looks like a variety of r/r's will work, so I will likely pick up the least expensive one. My question is which r/r from the R1 will work or will both. From what I can tell there are two, one has a single connection...

    Replacing the R/R Unit

    Hi There, looking at replacing the R/R unit on my 85 max as i don't think it has ever been changed and eats the batteries even with an optimate going. Is there a certain spec i need to be looking for?:biglaugh:

    R/R questions

    93 VMax. I have been having some little hiccups lately with the bike and I think they have something to do with the charging system. When I check the voltage at the battery with the bike running I get all sorts of weird readings. At idle it's charging about 14V and when I rev it to about 3k...

    R/R brown wire??

    I have just worked out my '85 has had a different R/R fitted to it. Specifically, an RZ350 one! It has an extra wire - a brown one. From what I can tell it's to sense voltage. Can it just be connected to the red wire? Stupid bodgey wiring... :bang head:
