I can remember always jump starting my 1970 CB 750 Honda. Batteries back in the day were pretty unreliable especially motorcycle batteries. YUASA battery and I have had a long relationship with dependability and quality.. Today i guess it really doesn't matter what battery you buy the technology has come a long way from back in the day...
Back in the day, I always tried to park mine so that I could roll down hill and pop start it. If it sat for more than a couple days, not enough juice to turn over but always enough to fire the ignition.
