I have a 96 Honda cbr 600f3 and has been sitting for a year. I replace all the plugs in it and it's not getting spark sometimes or it's very weak. What's wrong with it? Where is it? What does it look like? I need detailed instructions here not really sure where and what are on these bikes thanks

 

Anything that has been sitting for a year may need a little oil down the cylinders to free up the rings.The oil that was there drains off,then condensation forms causing corrosion.Take the plugs out spray some fogging oil or pour about an ounce of 2 stroke oil or reg oil down there.With the plugs out and rags covering the plug holes crank it a few times,replace plugs and try again.And start with fresh gas,get rid of anything that was in there.
Have you tested a plug for spark or is it just not starting?
