Another Rectifier Relocation Post

[TEF]

Hey all - Checked out the other rectifier relo posts and didn't see this question - please feel free to redirect me if this has already been covered.

Looking for some specific experience-based feedback here. So I had a rectifier meltdown (Rick's stator and rectifier on an 08 I've owned for 12 years) a couple of weeks ago on a hot, high-traffic day, so I figure it's about time to relocate this bad boy along with the replacement. Not a fan of the Gen1 location since there's no little air vent hole in the plastics right there on the Gen2. I'm thinking about "floating" it on an aluminum mount basically between the battery tray support bolts under the battery (with room to breathe) or somehow in the open void underneath the ECU (I'm 8 over and no upper swingarm brace so plenty of real estate, and the wires should reach). After researching, I found one person who had done the under-ECU thing on a drag bike I believe it was, but wanted to see if anyone has experimented with the locations I describe or other creative/open places than the Gen1 location on a street-only, real-world-ridden Busa. Thanks

Get a mosfet unit. Problem solved

Rick's stator and rectifier

These will not last forever but more importantly people expect that the aftermarket version is better. From the failures of Rick's hardware I have seen here and among VFR owners I have developed the feeling that while the aftermarket knows how to produce electricity, they are not prepared to produce products for the harsh environment inside the engine. I think OEM is best at that task, even knowing that items like coatings and such on these bikes are not that great.

If it has not been done you need to pull as many of the power connections as you can, and inspect and clean them. The failure of power components is not a cause but it is partially a result of the overall condition of the systems. Sixteen years is bang on for loose and corroded connections. These increase resistance significantly and then tax the power-producing components. Over time that will burn them out again.

Never jump start a bike with a dead battery. That puts a massive strain on these components. People may get away with it with such a large engine and high power output, but I would bet jump starting contributed to the death of the first and or second set of charging components.

If you can cool the rectifier that is truly great. But dutifully apply all of the above as it significantly contributes to damaging heat.

Yup. All terminals and connectors painstakingly replaced and tested in 2021 (and been fine since). And of course, with this new replacement, all will be tested before hitting the streets again

Thanks for sharing, everyone - very helpful to those wondering how to alleviate or mitigate rectifier issues. Sounds like no feedback on the actual location question I asked, so if I go that route, I'll be sure to report back in hopes of helping someone else who may have a similar q

When the Gen2 came out, alot of people relocated the rectifier on the right side of the subframe, below the rear seat.
Relocation brackets were for sale at quite a few places for several years.
I didn't like the idea, as there is really no airflow there, and the rectfiers had to get hotter since the heat couldn't escape.
Suprisingly, there weren't any real issues reported from this that I ever heard.
However, Suzuki had a couple of rectifier/regulator recalls, for units failing, which in some cases they melted, and some had reports of small flames.
I remember that happening to a few members bikes.
The rec/regs mounted under the swingarm either did no damage, or put small melted spots inside the belly wing.
The rec/regs on the subframe...yeah, they burned a nice big hole in the tail and got the sides of both seats...I like it under the swingarm, lol.
But, alot of bikes have the rec/regs in hot places. The 17-24 Gsxr1k's is mounted directly on the left side of the engine block.

I agree with sixpack. If there ever is a fire, the least bad place for it would be right where it's located plus, it gets about as much air as it can down there. My OEM rectifier is still on the bike after 13 years and I never did the recalls. I plan to replace it with a MOSFET someday but I will probably mount it right where the original is.
