Yes it might be hard on the battery, but if you are not in a position to charge the battery the correct way a jump starter can get you going. They really are just for a weak battery not a dead one. Sometimes after setting for an extended time you just need a little help. If the battery is dead then a new battery is in your future. For a motorcycle, size of the package might be the most important thing. Small is good.
O-W not sure I understand the comment on it being hard on the charging system. Haven't you said that with our shunt style regulator system that it runs at 100% all of the time. So it powers the bike and anything left over is used to charge the battery. When the battery is fully charged then the extra is sent to ground. It is running a 100% output all of the time just sending it to different places. Is the charging system on his V 300 different?
, I might add, this goes for cars & for motorcycles, etc, if you watch the video post #3 with Joe, you notice he said to wait then try it. That would apply to a motorcycle , if jumping, have the car turned off, wait a couple minutes, try starting the bike with the car off,generally a car's charging system and battery are 3 to 5 times bigger/ more capacity than a bike.The battery if just discharged, that is something drained the battery over say 3 or 4 hours of sitting, will have a very low resistance, this low resistance will allow a much higher charging current than normal. Waiting while connected to a booster source, allows your discharged battery to come back up with a lower current, than if you just boosted immediately.What happens after, is I mentioned shorter life using a shunt regulator, that battery becomes a load rather than a source of auxiliary power during times such as when the fan runs.
Will there be doom and gloom in the X300 or the 2020 V650, not likely, they changed the winding configuration in 2012 and again in 2014. We still get stator failure, but from what I see, it appears that Kawasaki is converting to Series regulators on some models.
For now I have the plug and play on hold ,indefinitely, my parts are stuck somewhere between China and Canada. One thing I can say , and this is 98% sure that if you converted to a series regulator, that chances of having a stator failure , even at 60,000 miles would be a rare occurrence, having said that, there will be people getting 60,000 miles on their shunt regulator Versys 650 MK-3 , it is riding style and temperature/ riding conditions.
I really don't care if someone converts or not, eventually Kawasaki makes improvements , the 2015 wiring isn't one of them, wire is short length everywhere .
I am now looking at making instructions simpler . The plug and play was promising, unfortunately I don't like others being the guinea pig ,if it is going to fail, best for me to find out first hand, I prefer to fix my own mistakes. TTYL
