. It works great on the gas but does nothing for the up to 10% ethonal in some gas.Most definately store the bike with a full tank of gas. Working in the industry I can tell you. Our 5 million + gallon tanks have floating roofs to keep the air out... not only for epa but also to keep it fresh. Tell ya anything?Normally I simply shut the fuel valve at the end of the days ride.
I've let a bike set to long (all winter) with the fuel turned off and the fuel left in the carb evaporated. The varnish type material that was left plugged up some of the smaller carb ports. Had to totally clean out the carb in order to get the bike running properly again.
When storing for the winter I would suggest either leaving the fuel valve open and take your chances with leaks or close the valve and run the motor until it quits. Just don't let the fuel in the carb evaporate.
Another tip I can offer from the school of hard knocks is store your bike for the winter with a full tank of fuel. Stored one with a half tank one winter and found condensation had rusted the inner top half of the tank. What a mess that was trying to clean all those little rust particles out of the fuel system. Then going through a three step process to recoat the inside of the tank and finally adding a fuel filter to minimize any future problems.
None of these problems were on my Bigdog but suspect it could happen to any bike given the chance.
I'm not a chemists but I'm pretty sure that nothing is magically removing the ethonol out of the gas other than burning it.I started putting in StarTron additive in my bike this year. It is supposed to take the ethonol out of the gas so the bike runs smoother. I fill a 5 gallon gas can and add this as well for the snowblower and weedwacker also. Friends of mine that own a marina have been using this stuff for years and have said they have not had any problems with the boats carbs gumming up. I'm going to try it this riding season as well in the BD and see how it does. Now to answer the post question, no I keep my petcock on.
Seafoam... FTWFuel "stabilizer" was a great idea prior to the increased use of ethonal (shit). It works great on the gas but does nothing for the up to 10% ethonal in some gas.
My day job is equipment sales and most everything comes dry from the factory. When we set them up, we run fuel through them to ensure proper set-up.
If that unit is not sold within a few months, we almost always have to take the carb off, tear it down and clean it up because of the fuel break down.
It is extremely nasty stuff and breaks down quicker than ever.:bang:
Race gas
Sea Foam (have not tried but others on here like it)
and I am sure there are others that work.
Either way, most bikes don't sit for 3-5 months even during the worst riding seasons. If you get it out, top it off with fresh gas.:up:
Personally, I don't shut the petcock off as I should and there hasn't been a winter since I have been riding that the carb hasn't come off for one reason or another.
I am also not a big fan of the mid-winter warm-ups every couple of weeks unless you are actually riding the bike for 15-20 mins. My understanding, (limited), just starting a bike does not allow it to get hot enough to burn the internal condensation that can more harmful than just letting the bike sit.
To each his own and I will be the first to admit to going out to the garage and firing the bike up (when together) after a few rum/cokes just to here the pup if I haven't in a while.
