Hi,just want to ask,my battery were fine,bUt suddenly my bike cant start,so i change new battery. The previous battery is new too,just change it 4 month ago. Is it the stator?

 

It is possible to have a faulty new battery, but unusual.
Before looking at the Stator you should start with the rectifier / regulator.

 

Hi Azham, welcome to the forum.
Please take a moment to introduce yourself and your bike to us
We love pictures

my name is azham from malaysia,still new in using superbike. Cbr954rr is my first superbike

 

Hi Azham, hello to sunny Malasia.
Nice looking bike, enjoy the bike but take it easy as it's your first Superbike
Cheers

How do i know that the rectifier is out? Before this i change the rectifier because it blew when i was riding.

 

@Azham To see if the Rectifier/Regulator (R/R) is working, you need a meter. Typically the voltage on your battery will be between 12v and 13v when the engine is off. When you start the bike, the R/R converts the AC voltage that the Alternator is creating and turns it into DC voltage. You will typically see anywhere from 13.5v to 15v DC while the engine is running. That is what keeps the battery charged. Oh yea, welcome to the forum and enjoy your bike.

 

i've checked already,my batt voltage during engine running is not more than 13v,between 12-12.8v only. Must be the R/R right?

 

Did you check your Stator wiring for continuity? Are the connections to the Stator good?

 

Did you check the voltage at 5000 rpm? Check that, the stator continuity, and the connector between them.

At this point, I would replace the regulator and stator to have a 100% good system and be done with it.
