Anything over 14.5V can damage the battery and the electrical system. Do not ride like this.
Most likely you have a bad voltage regulator.. Best regulator (R/R) is a mosfet type such as FH020AA. However, these are expensive, beware of fakes.
Can also try a used mosfet type from a Yamaha, Kawasaki etc.
Maybe someone from S Africa can chime in as to what is available over there.

PS: double check your battery for damage.

It is hard to believe that the stator output could be 264VAC @3000rpm.!!?
.
Test stator AC voltage, should be about 60VAC @ 5000rpm.

3 stator wires, call them A, B, and C
1. A to B
2. B to C
3. C to A

Disconnect the 3 pin stator wire connector to run this test. The bike will run fine on battery power alone for a short while.

PS: if you really have 264VAC output from stator then you may have the wrong stator.
Can you post some pics?

Double check the voltmeter against household current, make sure it is reading right.

Put 1 of the multimeter probs on 1 of the 3 stator wires, and the other meter prob to earth, there should be no continuity, do that for each of the stator wires, there should be no current, if there is then you mite have a bad stator. When you recheck for stator out put when running, its more important that each wire is giving out about the same ac as each other. Check it like fizzy said.
As stated 264vac is way out.
Also take your reg/rec of and turn it over and look at the back, if its oem I think they have a rubber piece in the middle, if the rubber is bulging and bubbling then you have a bad reg/rec, but you need to rule out a bad stator, otherwise when you put a new reg/rec on, the bad stator will blow that one as well.
What year bike is it? Is it carb or fuel injection?
