Load testers are nice, but real world test are what counts!!!

9:45am ... bike has chilled about 2 hours outside .. measured temp 14f , battery showing 14.05v resting before starter tests.

starter cranks over engine and draws 165-178 amp range. choke is off, didn't want bike to start too quick. after about 2-3 crank cycles to measure amp load. choke is set to full. after another 4-5 crank cycles with choke on, bike still doesn't start. but the battery has done it's job turning over engine.

battery is allowed to rest 2-3 minutes. now measures 12.88v rest, under load drops to under 9v, battery acts like it's depleted.... I give it one last crank... engine almost starts. the battery has done it's job. engine is simply not wanting to start at 14f degrees.

fast forward to 10:15am .. temp raises to 18f degree outside, battery has recovered to 13.24v @24f ... choke is on.. engine cranks over fast... SUCCESS! R80G/S starts and runs great.



battery warms up to 26f degree at 13.01v with all the cranking


battery is depleted (80% DOD) with all the cranking at 12.87


Success... fast forward to 9:15am .. temp raises to 18f degree outside, battery has recovered to 13.24v @24f ... choke is on.. engine cranks over fast... R80G/S starts and runs great.
