I have a problem with spark plugs acting like they are shorted out.
The bike is a '81 250r. If i put a new plug in,it will run fine for about an hour
then crap out. If I pull the plug and hold it against the head the spark jumps
all over the place exept where its suposed to. The color of the plug looks
good,"brown and dry". With a new plug it sparks in the right spot and has a
nice blue spark. This has happened with the last 3 plugs I put in.

Any ideas?
