    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Hey guess what? An R/R thread!

100% certain I have a bad r/r after reading the Stator Papers and going through the entire test phase. By the way, that is the single most useful and straight forward testing protocol I have ever had the good fortune to use, many thanks to whomever put that all together.

So I need to buy an r/r. Ok, fine. I've seen the list of compatible ones, but I want to know if there's any particular one that stands out heads and tails above the rest. If I'm going to drop $100+, I'd like to buy the best one I can.

So what are people's thoughts? As of right now, I'm leaning towards the 07 CBR1000RR one; I may be a little CBR biased.

Or is it simply a crapshoot and most new ones are pretty much the same?
 
Hi,

For the utmost in r/r technology, read this: http://www.thegsresources.com/_forum/showthread.php?t=161397

Any of the newer compatible Shindengen r/r units will be fine. They are much more robust than the stock Suzuki units. They are not nearly as stressed and run a little cooler.

Be sure to check out the updates/addendum to the Stator Papers written by Mr. posplayr. They are in the Electrical section on my little website.


Thank you for your indulgence,

BassCliff

Also do a search for threads on Comufire brand.
Jim (posplayr) has made a strong argument for the series type r/r in that they will in theory allow the stator to run cooler.

Instead of shunting the excess voltage to ground they basically 'turn off' the voltage during the period where the battery is full.

The newer FET type r/r's are basically the same as the older type r/r, ala the shindengen sh232-12, but use a FET to control the flow of voltage as opposed to an SCR. They run cooler due to the FET being an efficient manager of the voltage 'switch' and they are capable of handling a much higher amperage as well.

Many on this site have installed an older shindengen 232/532 etc and run many happy years without a failure.

I currently have a shindengen sh532-12 installed on my 79 850 with another spare sh532-12 in the wings and an FH010 as a backup backup:-\\\

If I remember correctly the Compufire can be bought for around $110, the FH models on fleabay for around $65 and the honda r/r for $40 and up.

As posplayr will tell you, an ounce of prevention, that means clean all contacts, take the fusebox out of the charge loop and install single point grounding.

Hope that helps!!:D
 
Would a SH 232 12 7.5 work? Or does that imply that it's a 7.5a unit? I don't understand how the model numbers work.

Edit: or a SH532-12 1.0,

Yes, as long as the R/R is of the sh232-12 or sh532-12 they tend to be a stable platform.

As Ed said, the FET models are at the top of the shunt type R/R's due to the reduced heat from the R/R and their efficiency.

The one he linked to is at a competitive price as well!:clap:
