I have a 2003 cl1200, the battary is new, when the bike sits for two days the battary gets weak , if longer goes dead, please help me

Have you had the alternator check for a bad diode it may not put out enough to keep the battery charged after 10 to 14 days. The bridge in the alternator could be weak. Hope this helps.

Yes, battery, if weak can cause hard start, due to low rotation of the engine thus less compression build up at cranking.
You can also get the battery tested to it's ability of the cranking power via a battery tester which has volt meter and a button to test it with a load that of an eqivalent of a starter motor and the meter would show the indicator to red if weak and if ok it would show at green! hope this answer helps.

replace ignition switch.

What is it doing, or not doing? Got lights? got dash? need more information!

new alternator

1st: Battery needs to be checked (no weak or dead cells) then fully charged.
2nd: If battery is good and fully charged, the problem could be excessive amp draw from the starter, a starter draw test would determine if the starter is drawing too much battery power.

First make sure the terminal and posts are clean and greased.

Then make sure the alternator belt is tight.

The type of battery makes no difference as long as it fits.

What matters is whether or not the alternator is putting out 13.5 volts or higher, in order to keep the battery at 12.5 volts. Put a voltmeter on the battery and rev the engine.

if you are using "AA" size, do NOT use typical alkalines in your camera, they die too fast. Buy rechargable NiMH batteries and a charger at Walmart or somewhere. These will hold a charge longer for you. Also be sure to turn off teh camera when not shooting because the camera is always draining battery life when "on."

Have the battery and the alternator tested under a heavy electrical load. Some of the cheap battery testers will not indicate a bad or weak cell. Also your alternator may not put out enough amperage to keep up with the electrical demands placed upon it. A good battery tester is a carbon pyle tester. Good luck.

Check the fuel pump maybe it got worn..
