Topic: I have no spark!!!!

[73 cb500]

 

     I recently acquired a 73 cb500 for the amazing price of FREE!!! the only problem is it has no spark. Can anyone please give me some guidance  on solving this little dilemma?

Free is good.
 I got a 72 CB500 that way.
 How do the wires look? The wires get real hard and most of the time need's replaced. From what I remember from my 500 last year.
 Are you running stock ignition?  How are the point's?
 Is this your first bike?

How did you determine there was no spark?
It won't spark without a charged battery, you know.
Probably want to check the handlebar kill switch.  Must be in the run position.
Are you getting 12 v across the open points?
Are your spark plugs shorted?

So many questions.  You need to elaborate a bit more. 
Or, increase your mental projections so that we may hear you better.

Good battery, ignition switch on, kill switch on, clean points (contacts to you yanks) and it should spar

thanks for the help everyone! Turned out the points were dirty. cleaned them up and presto we have ignition!. 
Now on to rebuilding the carbs!  Looks like a rain forest when i open the petcock. Well what should I expect from
free bike that has been sitting for 3 years.

Now Now, I am a "yank" and everyone  I know calls them "points"! Lets not get started on this, otherwise I will have to start harrassing about the imperial gallon!

[bryanj]

Nothing wrong with the imperial gallon, Just for once its the brits that have something bigger!!

[eldar]

Maybe so but us americans can use bigger numbers!
