1st of all, Hi everyone here! I'm new to this website and to the motorcycle world. Recently, I have just purchased a 1995 Honda CBR 600 F3 with 25k miles for $900. The bike doesn't start right now because the previous owner hasn't start or used it over 6 months. I just bought a brand new battery because the old one is dead. I tried to start the bike but it wouldn't start. I've read in here saying to check spark plugs, fuel and timing. I check the spark plugs and there is spark on 4 and fuel does get to the carburetor.
Right now I'm trying to take out the carburetor. I can't raise up the carburetor even when I've loosen all the screws. I'm stuck here right now. I have searched on the forum but no luck on any instructions and the service manual I have, it only covers some of instructions not step by step.
Am I doing the right things? which I mean is taking the carburetor apart to clean or is there a filter need to be cleaned? Sorry for the long post. Thanks all

 

Check to see if your petcock is in the right position before you go ripping apart any carburetors. Also check your fuses. Do you get electric when the key is on?

And, it is custom in this forum that you introduce yourself and your bike in the new member thread so that we may be better able to help you by knowing your backround and bike history.

 

Does it just crank and backfire?

It;s not easy to get the carbs and boots off the intake ports, especially if you're the first to do it!

You need to use leverage via a pipe or wood to pick them up on one side at a time.

 

it's just crank, no back fire, that's it. the petcock is at on position. I think the fuel is bad. I think It needs some new fuel and the carb need to be cleaned. I've checked every fuse and they are all good. Every light is working except the engine.

 

Wassup bro, i had the same problem, i thought i might break something if i push to hard to get the carbs off,but if the bike has been sitting for awhile,or poor maintenace to the carbs,getting them off or breaking the screws loose YOU GOTTA PUT SOME MUSCLE INTO IT!once their off its smooth sailing from there.I got some carb pictures in my album.Just my 2cents:Change the fuel filter while you have the carbs off as well.

 

crank it over and then check the plugs to see if they are wet, if not then there is no fuel getting there, if wet then it's probably bad petrol, try that before taking anything off
