My motorcycle is idling high and jerking what could the issue be?

Question

Granted because of the heat, I have not ridden in in about a month, so the battery keeps dying.

Answer 1

check your throttle cables,,,,,,,,,

Answer 2

Well, the fuel isn't *that* old, so I doubt that it caused any significant amount of gumming up in the fuel delivery system. Granted, it's always best to drain the fuel system or add a fuel stabilizer if the motor isn't going to be used for several weeks. The carburetor will need to be adjusted. There will be an idle adjustment screw somewhere. Find it and turn it in all the way then back it up 1.5 turns. Start the bike and listen for its note. Adjust the screw until you find the desired idle.

As the bike sat for a while the battery discharged itself bit by bit over that time. Although you could give it a charge through the bike's alternator, it's best to hook it up to the charger overnight. Both problems are minor and should be cleared up by following the advice here.

Answer 3

Yank the battery out, inspect it, fill to the upper fill line with distilled water. Put it on a charger like the Battery Tender Junior, and charge it up.

It's probable your tank of gas has gotten some condensation (water) into it, and maybe your carburetors have gotten some gumming. You may want to remove the gas and get a fresh tankful. And/or add some "carb cleaner gas additive" made by gumout and others. Be sure to get the gas additive, because gumout confusingly makes another carb cleaner product that isn't a gas additive. Use only a quarter of the little bottle, and tightly seal up the little bottle for future use (or pour the rest into your car).

Answer 4

if the battery keepsm dying replace it because you likely killed some cells preventing it from charging all the way.

In the future get a battery tender to prevent this. - http://www.cyclemartusa.com/productdetail.htm?productId=2403618&searchProducts=battery%20tender

As for the idle there are more than a couple things but this will get you started -

1) Check the idle screw. turn it down. If the idle screw is too high it will also cause it to jump off the line when starting off.

2) the gas could be bad. Fill the tank and try to get a tank through ans see if ut starts running better.

Answer 5

you need to tell us what kind of motorcycle it is. If it's an F4i it could be bad fuel pressure regulator. otherwise a lean condition due to clogged jets on a carb'd bike could cause it to idle high. Go to auto zone and get some sea foam and run it through the gas.

Answer 6

unbalanced carbs in a multicyclinder engine would do it, or clogged jets in a single cyclinder. Dump your old fuel,(yes it gets stale after a while) and spray some carb cleaner down your carb's intake while the engine runs.

Answer 7

Your carburator is probably clogged up (dirty) and needs cleaning. This usually happens when your bike have not been used for a long time.

Answer 8

if it is a 2 stroke, it sounds like an air leak. other possibility is carb problems
good luck
