I am on my second 12v motorcycle battery in a couple of weeks. Will a faulty regulator, ie too higher volts, cause this? Also I have upgraded my ct110 to a 160cc, without upgrading the stock reg. all works well for a few days, then gone.

Welcome to the site. Yes, a faulty regulator can cause it to overcharge. if you find the batteries were boiled over (liquid came out of the caps), it could definitely be overcharging. You can also put a multimeter on it to see if it's getting too much juice. Anything over ~14.5vdc would be too much.– Pᴀᴜʟsᴛᴇʀ2 ♦Aug 5, 2017 at 0:59

Your best friend with a questionable regulator or frequently failing batteries is a voltmeter.
Recently I had a battery go dead after a couple of days. It turned out that it would charge OK, and the regulator worked OK, but the ignition switch was intermittent. After several hours with the generator/alternator disconnected, the battery would be dead.
See if you can get a voltmeter, to carry with you, and frequently monitor what is happening. Then post your findings. You will get much better help.
But to answer your question, yes a disfunctional (over voltage) regulator could cause your symptoms. A low cost voltmeter will be less than your next battery.
