    Winterizing engines

    This is what I do to my engines when winter hits. Mower, genny, weed eater, power washer, motorcycles, boat engines, any engine that will not be used for 4mo+. Do you do anything different? do you recommend changing any of this?

    1) Replace fuel
    - Get fresh fuel, add stabilizer at storage dose
    - Pump out old fuel, replace with new fuel + stabilizer, fill less than 1/4th (?)
    - Run engine until reach operating temp and stop
    Q: on carburated engines, I run until all fuel is consumed and store with dry carbs and dry tank. Is this better than leaving stabilized fuel?

    2) Change oil + filter

    3) Change/clean(K&N) air filter

    4) Fog engine
    - Disconnect spark plug/disable ignition
    - Squirt Sea Foam in airbox while cranking
    - Reconnect spark plug/ignition

    5) Store

    I read some people mix fuel and 2T oil and run their injected engines until they smoke/sputters. Is this really worth it?

    I've always used a full tank during storage to reduce condensation and thus water in the tank. Even more important if your garage is like mine - it's not heated per se but stays a lot warmer than outside since its in the basement. Going in and out during the winter or leaving the garage doors open for extra light while working will cause condensation from the rapid temp changes.

    Step 1, winterize the mower, weed eater, and other yard tools.

    Step 2, man up and ride the motorcycles all winter, problem solved.

    Store with full tanks with a little fuel stabilizer. I wait to change oil in the spring. I like to keep the tires off the ground and inflate them to 40-50psi.

    Our winters are pretty mild and my bikes don't usually set for more then a couple months.

    I plan to ride the triple and WR all winter long, but track is going to sleep till next track day. I might put the WR to sleep too, offroading sucks in winter.

    What about storing dry? do you see any problems with having dry carbs and tanks?

    I understand the condensation problem with half tanks, but what if I suck and discard the gas before riding in early spring?

    In the past on my carbed bikes I would fill the tank, shut off the petcock a few blocks from home and run until she dies from lack of fuel. Then I'd drop the float bowls and toss the gas remaining in the carbs. Come spring, I'd just turn on the petcock and ride. Never had the need to throw away the old gas as it stayed fresh enough with a bit of stabilizer.

    Winterizing engines

    metal tanks: full of fuel - empty carbs
    drain oil - there are acids in the used oil from the combustion process that can pit internal bearings and parts.
    tender the battery
    check antifreeze level for temperature protection
    wash the bike. dirt will cause rust also

    this is a tank i just re-coated because i could not keep the rust out of the carbs

    after re-coat.

    Welcome to the Land of Suck, our endless horizon tends to provide 20 mph average wind speed for the next 6 months. The brutal reminder for the past 3 days of no sun, 45ish temp and unrelenting wind has already turned me into an indoor hermit. (Need to start working on shortening the outside to-do list).

    I have to confess that I have been pretty bad at doing anything lately, except for buying new batteries... My garage (cold side) rarely now gets below freezing. I have engine ice in the CBR so I don't have to worry about it freezing up. Working at the Honda shop years ago, the common problem with bikes that didn't start (with good battery) was crap gas in the float bowls - we would drain it and turn the petcock back on and see how they run.

    I bought many non-running or badly running bikes that had "carb issues" that generally were from that crap gas turning into crap varnish and changing your jet sizes... If I was to store one outside, I would top off the tank, drain the carbs (usually are accessible drain screws) yank the battery and wrap a tarp around it (mice would be my only real fear then). Keep the battery indoors and keep a charge on it and you should be able to go out install the battery, prime the cars and go. Then change the oil after the first ride...
