BATTERY NOT CHARGING 100%, regulator problem???

[stormi]

but even if it was the starter, that cant explain why the battery voltage drops as the revs get higher

 No it doesn't.  I still think this is battery related.

When I rev up to 10K, and let go, the voltage jumps to a number higher than when i let go at 5000rpm
although it never goes past 15volts

Maybe it's just pissed at you for free revving it that hard?  I'm not sure how much science there is in that, since we don't have any expected behaviour for that sort of action.

Starter turning faster.

If the engine fired, wouldnt that mean that the engine would start?

Nope.  It means that it's close, but not necessarily that it will start.  As spark and gas are delivered to the combustion chamber, there is an explosion, but if there aren't enough in a small enough time frame to get the engine moving, it's just a lot of fanfare for an almost start.  

I am sure that when I had the same problem that I replaced the battery and everything was fine.

is there anyway to find out what year the battery was made just by the words on the battery?

These batteries are a pretty big expense. How much did u buy yours for?


When the engine turns and theres a spark, there is usually a "popping" sound coming from the exhaust, isnt there?

When I was holding the starter, there was no popping sound at all, just the faint sound coming from the exhaust pipe and the sound of the starter whining

Not that I know of.  My battery is a "cheapie" made by ( or for) Parts Canada (same as part unlimited)  If you're in the US, I'd assume that you should be able to get the same battery.  I paid something like $53Cdn for mine.

There can be noise, but it's a pretty small one with a 400cc engine. I'd liken it to running your thumb over a comb, but a little lower pitched.

Okay you say your bro checked the bat. and it was good so lets say you take the starter out of the bike and test that ! How you say get some good old jumper cables and open your car hood with the car off connect the cables to the car and the positive to were the starter wire hooked up, now hook the ground to were the bolts that held the sarter to the motor were (1 of the to bolt holes I dont care) OOPS i forgot to say hold on tight if ti flew out of your hands its good if it made some nasty ass sound and barely turned over id say you found your problem! If im right this was a good show anyway!
cheers

Any of the dealers should have a parts canada catalog.  They should be able to source the number for you.  Alternatively, if you have more patience than I do, you can look through here: http://www.partscanada.ca/catalogue/2006/mc/en/index.html

The battery actually says Parts Unlimited on it, so it should be in that catalog. You could try this number:165394  apparently list is: $37.95

The battery # that is on the battery is YTX9-BS (I think, double check this of course before you buy it.)

The Starter works, and it defenately turns when battery is fully charged by battery charger

I think if it flies out of your hands, it might be prudent to test it again after you retrieve it from the bush, or the side of your car too.

I suspect that that's for the Parts Unlimited one, I think the $90 is for the yuasa one, but let us know.

$90 sounds about right. I bought 2 or 3 yuasa batteries when my regulator went bad. And they turned into $90 toxic paper weights!

[Stealth]

I went to the store a couple days ago, the YUASA Batt was $80 and apparently they didnt have any Parts Unlimited Batt's because "they dont believe in selling crappy chinese parts to customers"

[gsxr400 racer]

yuasa makes the battery for parts unlimited with there name on them!
