Running like s***

[2step]

OK, its been sitting all winter, started her up and she runs terrible. I changed the plugs still no better. Going to try Seafoam, how much or will it hurt to put a full can to a half tank or so?

Thanks 2step

I've put 1/2 a can in half a tank then filled it up. That helped a lot.

A full can won't be a problem although a half can should be enough.  If it's been sitting all winter you fuel may be very stale. 

I would add the Seafoam and then fill the tank with fresh fuel.

+ 1 on the Techron. Give it some time to work, run it then let it sit overnight, run it again, do this several times if needed. Unless the slow jets are completely plugged or your problem is rust/debris, the Techron should do the trick.

Had a silmilar probelm last year, tried Seafoam and problem  continued.  My slow jets were gummed up.  If the Techron does not clear up your problem, then I would guess the slow jet(s) are clogged or gummed up.  I wound up taking my carbs apart and replace the stock #35 slow jet with #38 slow jets.  The #38 slow jets are less prone to clog or get gummed up, since they are a little bigger.

The same thing happened to me... Had to clean all carbs due to fuel going sticky. Best thing I heard was to let it run out of gas when storing it.

Had a "Wing" that would barely run up the mountain, spittin and sputtering and i put in a whole can of "Sea Foam" ,rode it on flat groung for several miles than it screamed up the mountain, so i became a believer in "Sea Foam"!
But Techron is great stuff too!

I agree with bostonrats...it's probably stale gas. Drain it and start fresh. The Seafoam or Techron may help also.

Do you put some type of Stabilizer in the tank before winter starts?

If so, do you run it enough to get the stuff into the carbs?

And last but not least, do you fill the tank before storage to keep the inside of the tank from rusting?

I throw a whole can of Seafoam in MGM, fill it up, and ride about 15 to 20 miles and then come home and put him away.......

In 12 years, he has not failed to start and run good except for when the starter relay took a crap at 230,000 miles.........

Well I guess the seafoam did it, it took a whole can and a couple of days to get everything cleaned out, but it seems everything is running fine now. Thanks to everyone.

If you're going to let your bike sit for an extended period of time, drain the float bowls. You drain them by loosening each of the bowl drain screws (slotted screw on the bottom of the bowls; facing outward) 1 to 1 1/2 turns. Doing so eliminates the possibility of jet gum-up.

I have begun to leave the drain screws open on my bikes for the duration of winter storage...that way if the fuel valve should happen to develop a leak, it won't result in a hydrolock.

Come time to break the bike out you have to prime the carbs. This is where your MityVac comes in; using it will allow you to fill the bowls with fuel  without  running your battery down due to excessive starter cranking.

Move the vacuum line off the #6 intake runner and connect it to the MityVac by means of the pointed adapters which come in the kit. With the drain screws still open, turn the fuel to "RES" and pump the 'Vac until you get a dribble of fuel from the carb drain hose. Next, snug up all of the bowl drain screws and pump the MityVac for a couple of minutes. Replace vacuum hose on #6 intake, add battery...start bike up.

TECHRON, and use a triple dose.
