just got a cbr600f,
it had been sitting for three months without running and started easily enough after a couple of trys.
its been sitting now for maybe 2 and a half weeks and wont start, ive just replaced 3 of the four spark plugs, couldn't get the last one out because of the fan, but it still wont start. right nowi'm charging the battery and i'll try again in an hour or two.

if it still doesn't work any suggestions?

 

Charging the battery should definitely help. Sometimes even if the battery will crank the engine, it still won't start. Myself and others have had this same problem. A fully charged battery should do the trick. Make sure the engine kill switch is in the "run" position!

 

Try jump leads from a car battery. I've just had to do the same after my engine rebuild and it hasn't been run for a few months. The battery charged up fully but it stil wasn't quite enough. A jump start got it going.
The ignition systems on Hondas are not all they should be. A new battery may help. I'm going to get me a new one tomorrow to be sure.
Also make sure you're getting fuel through. It can take some cranking just to get the juice running ot the carbs if they've gone a bit dry.
How come the fan stopped you getting a plug out? That doesn't sound right. Have you checked the manual to see if there's any info on that?
Luck! It'll come to you.

 

You need to pull the tank up to get to that tough one.. did 3 of mine without taking the tank off but # 3 has to mush crap in the way..

While you have the tank up hit the carbs with a little starting fluid. I use to have to do that with a old Suzuki if we let it sit for to long.. You can also pull a plug, ground it to the block and check the spark. should be bright blue if memory serve me right..

 

when i changed my plugs, I took the tanks off first. After that, I bought a 6" wobble extension and a socket cap you can turn with a wrench. That solves the problem of being able to get to the plug by the fan. PM me if you need any help. I just did this last week.

 

I have two hurricanes one of which I am restoring.
I would suggest getting a wobbly ext for the plugs as that is the only way to get to the plugs.
Second I had this issue since my bike has not been on the road since 2003.
If you hear a click click its your starter. Not the relay bc the relay is good if its clicking.
Make sure the battery has the acid or distilled water in it correctly.
Also on the side of the bike is a fuse make sure that is there.
Its hanging off to the side. Mine wouldn't start without out it.

Email me if you have any other issues...
