In ideal conditions, the starter draw is between 70 and 90 amps.

It can go much higher especially if the grounds are dirty.

Here's what I have, but I haven't used it to jump my bike, always somebody else. Battery Tender lead is for charging the battery or for using my air compressor.
Ray, despite your mistaken perception that the root beer brown is fast, it is a very nice looking color, and looking at that wiring i’ll Add that you do very nice work, good job !

Now, there in lies a possibility...
You could connect you battery booster pack to that lite gauge pigtail, energize the pack and then try to *pop the clutch....

You would jumper the power to the ECM and ignition, allowing a start, if it is possible.

FWIW, contrary to my younger year concepts, I now know that you don't *pop the clutch in 1st gear, but rather a higher gear like 3rd or 4th. Much easier...

If its got teats or tires, your bound to have trouble with it...

True. The battery is new. Just looking to prevent any future troubles... And i know from past experience when bump starting is a waste of time..

Ray's bike is ready for the "apocalypse", but he can out run it with that Root Beer rocket! LOL
