Is the new battery a sealed Maintenance Free-AGM, or an old style where you have to add water to it?

There is an occasional bad battery right from when it is new.
Try giving the battery a full charge and take it to a battery shop for a load test before giving up on the bike and stator.

The battery was put in around the first of May because we thought that was the issue..no the battery is the type you have to add the acid to.....everyone keeps telling me what the book value is on it I just don't see me putting any more money in it......

what does book value have to do with it? It's not an investment most vehicles will only lose value. The question you should ask is what is it worth to YOU not everyone else. Mine is a 99 and between stator R/R new seat backrest removal tires Custom battery box I probably spent a grand or better and to me it's worth it because I know what I have.

Second you need a maintainence free AGM battery. the flooded batteries tend to boil off into the battery tray and destroy the tray r/r and frame sometimes.

I just put a new MF-AGM battery in my bike this spring, and I had to pour the acid in from a six pack set up, then pop a sealing strip into filler holes. So from your explaination, I am still unsure of what type of battery you have.

The old flooded cell battery has six caps that screw out to add distilled water as it boils off.
Never add more acid to a low battery, water only.

I agree with vulcanjoe about spending money on a new stator.
It may be the most cost effective way to keep riding.

What is the bike worth to you?
Do you like riding this bike, or are you looking for a reason to buy a new/different one?

Hey mom be sure to test the stator before you yank it out.
It is not that hard to do. A cheap multi-test meter from auto zone will do the trick. Go to the vulcan verses and find the info.

But be sure that all the main cable are clean and tight.

This could just mean that some crud or tank rust is now in the carbs and/or something constricting the flow of fuel or air to the carbs making it run rough.

When my stator bombed, the bike ran fine, I just had to charge it maually every day. If your bike was spitting & sputtering, I'd lean toward some other problem besides the stator. The stator is only responsible for charging the battery. But at idle, the the stator doesn't charge anyway so if your battery is skimp, it could run poorly or die but should improve once the engine rpm go above 2k or so. Like niterider said, take the time to test it. That's a lot easier than changing it. Sounds more like a fuel issue to me.

Also, I agree with VulcanJoe & 'OlHoss....book value shouldn't have any bearing on repair cost. This thinking is only true for Dealers but doesn't really count for owners. So, if that's the only thing that the value is based on, then nothing would be worth repair. If the bike is a basket case or you just hate it, then that's different. But, if the bike is in reasonable shape and you like it, then it is much cheaper to repair it than to replace it (This is true with any vehicle). That's the way you should think of it. You'll never get all your money back anyway so why not fix it and ride it?

Given the voltage at 4k it does sound more like the stator rather then the carbs. Even at idle it should be at least 12.8v as long as the battery is good. Like others have suggested trickle charge the battery over night and have the battery tested and go from there.

If you don't have a payment it is worth putting the money into it. Buying a new bike plus adding mods to make it original to your style will cost much more then repairing what you have. It's a love-hate relationship. You love to ride it but hate it when you have to work on it. lol
