I would use a trickle charger. After being stored from Nov-April, the S2000’s tiny battery didn’t have enough juice to tackle the 11:1 compression and we had to use a jumper pack.
Just adding tire pressure works fine. Make sure to keep your race tires in a climate-controlled place though. Heat cycles + extreme cold kill R-comps.
I wouldn’t worry about the plugs or lubing the cylinder walls, they’ll be fine.
