i have a f2 600 94 cbr honda in my garage and i tried starting it but when i try to start it all it does is make a loud click then i jumped it with my truck and it turned on, i left it running for a bit and ran fine but the minute i turned it off it died and i had the same problem again.
The battery is new i bought it 3 months ago
i have had it sitting in my garage without riding it for a couple of days
it just won't start at all

 

sounds like your new battery isn't holding up. the click is the starter solenoid trying to make the starter engage, but your battery doesn't have the juice to push it over.

At idle, motorcycle stators really don't charge the battery, it needs to be turning some RPM (driven) before that happens.

Or, you possibly have a poor connection somewhere Ground or Positive. but if you're jumping directly from your car's battery terminals to the MC batt terminals - I'm putting money on a weak battery.

New batteries need to be properly charged before being put into service, and if not ridden every couple of days (not just fired up and left to idle in the garage), the battery could easily lose full power.

 

+1 What he said.

 

same thing happened to me the day i bougt my bike i left it running with the HID on. haha i was so angry and i panicked but just trickle charge your battery, or jump it then go for a mooderately lengthy ride (1/2 hour)
