Vstar was fine in the garage. Went to start it the other day and it seems to be draining the battery. Full charged battery will get it to barely turn over. Removed plugs and turns over no problem. So far I have replaced starter,plugs and changed the oil and filter out. Any help would be great. Thanks

Noticed this is your first post. If you post a little something about you and bike in the New Members Introduction section we can get to know you.

Couple questions, how cold is your garage and what weight of oil are you using. Higher viscosity oil when cold can cause the motor to be sluggish turning over. With everything you replaced has me believe there is a corroded connection some where. It's common for the negative cable where it grounds to frame to become corroded causing you describe issue. Follow the negative cable where is leaves the battery to find that connection. Even if it looks good, take off and clean. Report back if that cures the issue. Good luck.

How old is the battery? If it is more than 3 years, it is likely the culprit. Unfortunate cost of our hobby/lifestyle.If you have a multimeter, can do a quick check on the battery by doing a load drop test. It should read around 12.3 Volts at the lowest, preferably closer to 14 on a good hot charge. While the the starter is spinning, voltage should momentarily drop to around 10 volts and then come right back up to close to what you started at. If it drops lower, then it is a weak battery. If it drops out significantly then bounces right back up, then a bad cell. If it trickles down to like 8 volts and trickles back up, then it's last leg. Otherwise, you can pull it out and take it to one of your local auto parts stores and they will be able to test it for free, Though they may need to charge it overnight to ensure that it has a full charge. Also, don't hold the starter button for an extended period of time...few seconds will do the trick. With the bikes coming out of storage, this will be a frequent question/occurrence. Good luck and keep us updated. And if you are not in a big hurry, look online and you can find a lot better prices on batteries than grabbing one local.

Sounds like a weak battery, or corroded terminals. I would pull it and get it load tested, and while it is out clean up all the big cable connections.

Age means little on a battery. Lots never make it through the warranty period.

You mentioned a drain. Always possible. You can test for that. But I think the importance to your issue is that, draining a battery just a few times can ruin it.

A cheap test for you would be to pull the battery, put it on a bench charger for a least 2 days. Unhook the charger, leave the battery on the bench, and check voltage daily over the next few days. Should stay up around 12.5 to 12.7. It will be high on day one, ignore that. Batteries will stabilize after day one. That's a poor mans load test, and you can do it all faster by just taking it to the store for a real load test.

Also make sure you are getting a good output from the bike charging system. Voltage should in up in the low 14's when running.

@Candog, have been able to diagnose any more yet?
