I have a solar powered battery tender on the bike, works wonderfully

 

Just like was said. It would be safe to jump off any batt. Does not matter what size if it's 200cca or 1200cca. It is still 12 volt. Your starter will only pull so many amps. But yes hooking up with car running and alt on car putting out 14.4v may cause some problems you do not want to deal with.

 

I concur with this. Jumping off your car is not really a problem just don't start the car because damage can occur to the electronics.

 

I've jumped my bike from my truck while running a bunch of times and never had an issue.

 

Hahahahaha no ****!!!!!!!!!!! I was thinking just hop in the car or get a friend to take you and buy a new fricking battery that you clearly need and then you bitch slap all of us with this.... DUH!!!

 

You can do it. I had to do it when I bought my bike. BUt make sure you do not have the car running!

 

Dam I wish this thread would have started yesterday.

I boosted my bike for the first time ever with my Jeep and I had it running! I hadn't ridden for a couple of weeks and my POS battery tender is a worthless POS.

Luckily nothing bad happened. My regulator still shows an output of 14V.

 

Yeppers, you can jump any 12V motorcycle with any 12V car battery. 12VDC is 12VDC any way you slice it. The bike starter wont pull any more amps than it would from the bike battery, well for the sake of keeping it simple and to the point, let's just say this is true and save the technical end for another time. Like was said earlier, I don't recommend running the cage.

 

Yep - buy a hill

 

Just did that today....good thing there was a hill, not easy getting a 600 lb bike rolling on flat ground
