my cbr600f wont start, gets gasoline, has no spark,
tried to measure the current on the coils , but theres non , is this a common problem ???
anyone any idea whats wrong???

 

Can you give us some more info on your CBR 600 such as the year, does the engine turn over fairly quickly, is the battery in good condition etc. If you aren't getting a spark at the plugs then there has to be a fault in the ignition system (pretty obvious I know!) and you will need to get a Haynes manual for your model so you can check the ignition system in a methodical order to try and locate the problem. Sorry I can't be of much help at this stage, but more info on the bike would help.
