Hi!

Im having some problem with the battery if i drive longer rides (few hours) with headlight fully on witch the laws require over here even in dayligt my battery drains out, if I'll stay with parking lights (middle possition) it works okay.

Any one know whats might be the problem? R/R?

Got two poor vid's here from fault fiding.

Sounds less like the battery and more like the charging system. You can get the battery load tested at advanced auto on the free to rule it out. I suspect you have a short somewhere draining your battery or your charging system needs some tlc. I see the revving puts it to 14.2ish.

you need check this thread https://cbrforum.com/forum/f2-tech-93/regulator-rectifier-r-r-problem-solved-27739/

your R/R its bad and you need change it urgently because may fried your CDI or other thing.

When you start the bike and the idle are in 1000-1500 rpms your bike must have 12.8-13.2V and the maximum voltage was 15.5 volts at 5000 rpms or higher, but you have 17-18volts thats off limits.

so be careful and change the R/R, but first check the thread

Have read that thread now and also ordered a gsxr 1000 k2 unit from ebay. Will also test the stator with multimeter so I'll see thats everything is alright from there.

 

Your R/R should be limiting the charge your battery gets to around 14.5v @ 5,000rpm. Right now you're cooking your battery and it will probably smell unpleasant after a longer ride as battery acid boils over! Your stator is fine if it's providing a charge.
