This thread is pretty well beaten to death, but let me put in my late two cents... :blink:
Batteries: If you use an appropriate "float type charger" like a Battery Tender or Battery Minder, the optimal charge will be maintained automatically, without the danger of overcharging. 2 Amp trickle chargers left on constantly may overcharge and end up shortening the life of the battery.
A charged battery will not freeze in the temps we get in the lower 48 states. No need to remove it from the bike/boat/aircraft to "protect" it. If it makes
you feel better though, go for it!
Fuel Stabilizers: I'm not a chemist, nor did I stay in a Holiday Express last night, so take the following just as my personal experiences over the last thirty years of winterizing various internal combustion engines. YMMV!
STABIL - I have had poor success over the years with this product in everything from lawn mowers and weed wackers to snow blowers and motorcycles. The problems have gotten worse since only oxygenated gasoline has become the norm. Ethanol is definitely NOT our friend! I can't count the number of carb rebuilds I've participated in after the use of
STABIL. The gummy deposits found in the fuel system after a winter of storage required a complete tear-down, so why bother to use the damn stuff?
SeaFoam - I was turned-on to this additive over on a Kawasaki board I frequent, and since beginning to use it three years ago, have had absolutely NO problems. I use it at a slightly higher concentration than recommended on the container:
1.5oz per Gallon instead of the suggested 1.0 oz/Gal.
Since I switched over to the
SeaFoam, all the engines I use start very easily on the first go-round in the Spring. Have not had to do any carb work or adjustments at all... I run a tankful through all my power equipment about mid-season as well, just to help keep things clean, but that may well be overkill, who knows?
The stuff is pretty cheap, and I don't know about y'all, but I
hate tearing fuel systems/carbs apart to clean!
