K6 GSXR600 Reg/Rec Issue

[TheArchitect]

Recently picked up my K6 GSXR600 and have heard a number of times that this model suffers from the Reg/Rec burning out.
The guy I bought the bike off told me he had the problem occur and he had a new unit fitted.

So how can I prevent his happening again? I've heard and seen on YouTube that people relocate the unit. Is this safe? Are there any side effects to doing this? Is there a recommended location to move the unit to?

Thanks in advanced for the advice

Ps. Any other hints/tips/heads ups about this bike welcome!

Reg/Rec produce a lot of heat and need to be cooled in an air flow or a heat sink plate or both fitted.

Reg/revs are designed to run hot and there aren't many places on a bike which aren't exposed to the breeze. If the reg/rec has started to struggle then repositioning for maximum cooling is probably just allowing the rest of the charging system to malfunction and letting the reg/rec take the consequences. That can't last.

I'd fit a Mosfet reg/rec if it hasn't already got one. They are more efficient to start with. I'd also clean up or replace the charging system connectors with high quality ones, and where possible shorten the leads and run the reg/rec direct to the battery terminals instead of via the loom. Worked a treat on my R1 using Eastern Beaver products.

Also bear in mind that any under-performing component of the charging system can stress its neighbour, so if you're repeatedly having to buy yet another new reg/rec it's probably because connectors are dirty/corroded or the battery or alternator/generator are weak.

Most rec/reg problems come down to two things

Bike in daily use
Rec/reg will get hot ensure the heat path to the frame is good and as much as possible it is in cool air preferably moving cool air

Bike in weekend or less use
The above +
Be very careful of battery condition a poorly battery can kill rec/reg

I had this happen on my k6 a few years back, it had a nice burned line running straight through the centre of it. I now have an aftermarket one fitted with a massive heat sink attached to the back of it and so far it's been ok. Billing has the thou k6 and his is under the seat rather than down by the nose.

They are a devil to get to though as the connector is right behind the frame and you need someone with baby hands to get to it.

thanks all for the replies..

The bike is my daily commuter and weekend hoon all wrapped into one. Therefore I'm guessing I'm more likely to see the Reg/Rec fail on me despite it being newly fitted recently.

I'll be ordering a Mosfet unit as a pre-emptive measure for when it does go wrong.

thanks again

It's a common issue on the K6/7 600/750's. They over heat because they're badly positioned. I believe the K8 onwards GSXR's we're recalled for their rectifiers.

If you have FB, join the GSXR Owners UK page, post there and you'll get a lot of suggestions of what to do and photos of where and how people have repositioned there's. I believe a common one is using a tax discs to reposition it to the side of the bike (so it sits flush with your side fairing).

He's how my brothers one looked on his K6 750, it actually went into a small flame.

I replaced the above for my brother and it's easy to do tbf.
Tank up, airbox off, then it's just a matter of unplugging and unbolting the rectifier.

I just had a quick review of an excellent old reference which has been updated. It seems there may now be a better alternative to a Mosfet. I haven't read it all yet but;

Check the condition of the connectors regularly, Mine had fried, the regulator was okay but I bet a few stealers will have replaced and charged for a new reg/rectifier as that's what you expect them to do.
