it’s winer now and instead of winterizing my bike i filled the tank up full and put gas stabilizer in it and i start it once a week so the battery doesn’t go. the oil is newer too. i’m paranoid but is there any possible way i’m creating harm to the bike by doing this? it gets really cold in my garage and i have full synthetic 10w40 castrol oil in it. is it bad to start it up in the cold because it’s such a thicker oil??
