someone needs a new battery...

sometimes, i rarely go past 5k, i got an 01 with the original battery and it never died on me once yet.

 

it is a new battery [&o]

 

Your stator does have do spin up some to begin charging, usually about 2500 to 3k. You bike has a stator, not an alternator like a car so you are making more voltage the faster you spin the bike, which is why bikes have a regulator/rectifier which essentially turns excess voltage into heat. My 99 F4 had a weird failure of the R/R and it was charging like 22volts at high RPM. This fried the battery and actually melted wiring. Normally when the R/R fails your charing system dies.

 

you can cruise around at higher rpms than that if need be without putting much if any really,stress on the engine, thats not even half way to redline yet.

 

amen

 

lol or put it to second gear and pop a wheelie =]

 

I doubt if there's a big technology difference between car & bike - finally it's a magnetic field and coil moving relative to each other. The one that's stationary is the stator, the rotating part's the rotor, and the whole thing together is an alternator.
A well designed alternator, then, would put out enough voltage at the lowest rpm's the bike runs. Then as the voltage increases with rev, the regulator sinks the excess power.

If the bike needs to be run at high rpms (anything more than 2500), possibly there's excess voltage drop in the regulator... which might mean a regulator tending toward failure.

 

These bikes were built to be run hard and fast. I run around town anywhere from 6k- 9k. But I like to be heard when I go down the road. Loud pipes save lives.
