Went for the last ride of the season to put it in storage, just to find out that it wont start, battery is mostly dead. Havent started it in a month, and temperature between 25 and 40.

Now can i jump start it with my car? Or should i remove the battery and use a tender? I dont have a battery charger...

I just want to make a five minutes ride to the storage place.

 

Just make sure the car IS NOT running and it should be OK. And don't continue cranking it if it doesn't start fairly quickly. Done this once or twice myself.

 

I have done it with no problems, contrary to some posts.

I have also had the truck running to get it to crank.

Have done it at least a couple of times before I figured out the damn security will run the battery down if you pull the bike in a toyhauler for 1500 miles or so.

 

Do not jump it with the 4 wheel vehicle running, the bike's 32 amp regulator can easily get blown trying to sink the 100+ amps from the cage's charging system. You might get away with it once or twice, but sooner or later it will cost you $$.

 

With dead batteries and charging systems, it best to remove the battery for charging .
Why strain a stator or generator , there made to maintain a battery not charge it from a dead state.
Battery explosions get messy

 

The stock motorcycle battery can supply well over 100 amps...

12 volts is 12 volts, the only reason the system would draw more amperage than needed is if there were a short in the system or a defective electronic component, and even in that case the 30 amp main fuse would blow.

But there is no reason to have the car engine running to jump start a motorcycle engine...

OP: Buy a battery charger.

 

Agree with Dan, the bike will only draw the amperage it need , the reason that vehicles get damage when jump starting is usually caused by improper use of the Jumpers causing a high voltage spike during connection or disconnection .

Connect the positive cable (red)(+) to the positive post (+) of the dead battery. Connect the other end of the positive cable to the good battery. Connect the negative cable (black)(-) to the negative post of the good battery. Connect the negative cable to a metal part of the dead vehicles engine.

 

I did this several times in the cold weather with my 48 but the 4 wheeled vehicle was running every time and never had any issues. I guess I just got lucky. Now i just keep the tender connected when the bike sits for extended periods of time due to the posts I've read about the possible damage that may be caused.

 

If anyone selects to go with the C Tek tender, they have a pigtail with 3 different colored LEDs to tell you how your battery is doing before you try to start your bike. Unfortunately it is a different plug from the Harley tenders and they cost around $10, if mine is flashing red the bike wont start.

 

Study up on "shunt" type voltage regulators and how they work. If you grasp electronics theory, you'll see how easy it is to push 100+ amps through a regulator that's only designed to handle 32 amps. The shunt regulator that Harley uses is not like what's found in most vehicles today.
