i have a 04 crb 600 f4i that won't run...i got the bike out of storage and installed a new battery...it started fine and ran, but not very well...i thought it was bad gas...it was low on gas so i added 2 gallons of fresh gas...it started running fine...two day later it won't start up and run...it tries to sometimes but won't...i hear the fuel pump running but not sure what to do next or check.

 

Mine was doing that too; i figured the condensation/water got in the lines and I added some Seafoam and let it sit for a few hours and it came back to life.

 

I would have to agree with tyler947. When storing the bike you should fill the tank right up (and add fuel stabilizer) so that there is no room in the tank for water vapor to collect.

 

you might try changing the plugs too, or pull one to see what it looks like

 

i put new gas in it..do i add the sea foam to that and try and run it thru?

 

Even though its a new battery, check its voltage. Might be something on the bike draining the batt

 

probably fouled out the plugs running bad gas through it
i'd start by pulling them out and giving them a look

if your plugs look black then your fuel wasn't being burned completely and you'll have to clean the plugs or replace them

 

+1 on the seafoam i love that stuff
