2007 GSXR750 Fuel Pump Kablammo?

well, against my better judgement (and the advice of everyone here) I rode 'er home in the AM and other than the speedo conking out on the 407 and the smell of lovely fried battery when I got off the bike, seemed no worse for wear. Bike's being trailered tonight and diagnosed. Fingers crossed the ride home didn't reduce my electrical systems to a smoking ruin. Bike needs a massive overhaul any way being at 60,000 KM and a lot of things being original parts.

Appreciate all the replies, suggestions, and concerns.

once again, GTAM shows itself to be a great community

Cheers

I hope my previous post was not right or else you might fry all electronics on the bike. The rectifier is to prevent the voltage from fluctuating. When you revv the bike from 2k-7k rpm, the stator connected to the engine also increase in speed. This increase in speed, increases voltage, more like a bicycle dynamo, the more you pedal the brighter the light gets

I hope you're not right either... if it makes any difference, pretty much my entire ride is spent at 8k+ RPM in 6th gear as its almost completely highway from work to home

Is it better to change both the R/R and stator after a set period of time to prevent this issue? =(

I don't want me stuff exploding or leaving me stranded!

Using the same theory, you should replace your motor ... rebuild forks .... replace bearings etc etc as well. While you are at it...put in a new frame due to chassis stress over time?

Actually (sarcasm) aside - there are a bunch of things you can do to prevent issues and help extend life of those components. Why dump money into parts that don't need replacing?

^^ Please dont mock the way aerospace industry maintains the aircraft. After all its probably the number one reason we dont have planes falling out of the skies all the time.

If the OP chooses to do preventative maintenance, its his choice. The Zuk reg/rectifier IS a known failure part. If he chooses to replace it preemptively to a mosfet type who are we to mock him.

Also reg/rectifier not only maintains correct voltage, the regulate part, it also converts the stator output of AC voltage to DC voltage, the "rectify" part of its name.

It does so by shunting the negative part of the AC curve to the body as heat, essentially using the body as a heatsink. This is why they last a lot longer if placed in airflow, NOT next to the exhaust headers like on the 06/07 GSXR's

If that was my bike, and i HAD to ride it, i would have disconnected the Reg/rect and ran it total loss...

What you are saying. I will agree with 100%.

Replace the stock rectifier with a MOSFET . Very good idea. But replace it with the same stock part will in the same horrible location is pointless.

Even the stock unit on the gsxrs will perform so much better if they are relocated to a spot where it will have some air flow vs. right by the rad/headers.
