Can anyone tell me or measure their 2012-2015 WR450 amperage draw when starting their bike?
I measured mine at 80-90 amps, but don't know what range it should be in.
I measured the voltage drop on the positive side and negative side from the battery to the starter. Both sides had a voltage drop of 0.5 volts.
With that said I just started using semi-synthetic oil. And that has helped with the bike starting. It'll now start every time in neutral. When in gear it'll start up right away about 2/3 of the time, the other third I'll have to hold the throttle WOT for a few cranks, then no throttle before it'll start up. Or I can use the sure fire method of using the kicker.
My bike is a 2012, have a Shorai battery, 14Ah 210 CCA, competition ECU with the CO set to -5.
edit: with the improvements I saw with semi-synthetic oil, I'll probably try full synthetic on my next oil change to see if there are further improvements in starting.
