In order to make my superstock tail fit, I need to relocate my voltage regulator/rectifier. How hot do these get during normal operation? I am asking the question, because the easiest place for me to relocate it to is above the under tail like so:

Stock SV regulators get pretty hot. If you swap with a mosfet unit like the ones in late model CBRs or F1s, then they do not run too hot. Is your bike a 1st gen? If so, how old is that R/R? Have you checked your output voltage? They are usually toast after 10,000 miles.

they get pretty warm to the touch.
I cant imagine that the location you have now is going to get any less airflow than where it was mounted before so I dont think I'd worry about it, although if you're choosing a place to put it- somewhere with MORE airflow should be strongly considered, given the history of the stock R/R's tendency to crap out.
I have my R/R mounted in the same area, although mine is a larger unit from a GSXR.

It is a stock gen 1. It is original to the bike so far as I know. Mileage is somewhere around 15-20k. Given what you said, I might want to get a spare.

OK. I might just get a spare and let it eat. Thanks.

You could try to find some heat transfer paste from an electrical/electronics supply store. The kind they put between power transistors and heat sinks. That way a lot of heat would be transferred to the aluminum plate. Should help a good bit.

You should check it with a voltmeter. They go bad slowly and then they finally crap out, often taking out the battery and/or other parts of the electrical system.

Should be 13.5-14.5 volts at all RPMs. Typically, when they start to go, the voltage is fine at idle, but it drops at higher RPM (like down to 12.5).

Ok, thanks, I'll check it out.

as andy said, find a heat sink AND a CPU fan to cool it down, heat is what makes em go bad, relocate where is can get cooling air
