Portable battery jump pack

[flw]

I'm looking for a (bike only) portable battery jump pack, without over spending. I don't need/want to jump cars and its only for when I forget to turnoff a accessory for the night but need to leave in the morning.

Any suggestions on make/model for my Kawaski 500 LTD '07 (12 Volt) after price, weight is the next issue.

Thanks Dan

It's so easy to bump start a bike, why would you want to carry a battery pack?

How ya gonna bump start a fuel injected bike with a completely flat battery? What's gonna prime the injectors and run the fuel pump? That's all electric.

Unless the battery is stone cold dead, it will start. I have personally bump started FI bikes with a barely alive batteries.

Since the OP was talking about a portable charger, I assumed he was talking about roadside emergencies. When do batteries go completely stone cold dead during a ride?

I use one because I'm too old to jump start a bike, I'm happy I can still lift it off the sidestand and get going. I got one of these for Christmas 08 and got fired up immediately regardless of how cold it was outside the past 2 winters, a bit pricey maybe but charge it up on household current and your good for a years use per charge on a bike:

I had this very scenario two years ago. Like an idiot, I left my V-strom's ignition in Park all day and ran the battery flat. I tried several bump start runs - the fuel pump had just enough juice to make a kind of strangled gurgling sound - but no dice. The parking lot where this happened is on a slope, so I definitely had enough momentum to turn the engine over nicely, if it had fueling. Eventually a coworker who carried a portable emergency charger in his car happened along and bailed me out.

When do batteries go completely stone cold dead during a ride?

When the bike is the '07 BMW G650Xcountry my wife used to own. Bike started, went several miles, then died. Turned out the battery was toast. Wife bought the bike as NOS, dealer should have replaced the battery, but didn't.

I remember trying to bump start my old Gpz1100 back in the day, when I was still fairly young, healthy and strong.....think I managed it once. Even bump starting Sabre was a pain in back side. As for Connie, too damned big and heavy, either jump start it when the battery is flat or recharge the silly thing.

Wow that sucks. Did u complain to the service manager?

Well I see the different viewpoints of everyone. I suppose it would be nice to have a jump box at home but I certainly would not be carrying it around for roadside emergencies.

I know a guy that bump started his GSXR and messed up his timing. Of course the way he used that bike makes that claim suspect, but in the end his timing was off and the symptoms started around then.

No question, did something wrong. Probably rolled down a steep hill and popped into first.
