I was having problems with my spark plug getting carboned up with a non-oily deposit on my 1986 Savage with 13K miles. I thought it might be the carb and up graded to Lancer's kit with a K&N filter and a aftermarket Sportster muffler. It was running and then I couldn't get it running and took out the spark plug after cranking it over and there was gas on the plug. I then checked the plug on the side of the engine and got a red spark and then a blue spark. It did start running after I changed the new sparkplug with the older one, both sparked against the side of the engine. I am thinking it might be the igniter assembly and intend to take it to a mechanic and have the starting system checked out. I noticed on e-bay they have an ignition case off of I think a 2000 LS650 and theey specify 2 numbers a 32900-24B11, and a 32900-24B10. My # is 32900-24B00. Would this fit on my older bike?
Any other suggestions?

If it truely is poor spark I would check that the coil has a good ground to the frame. make sure that the frame is clean underneath the bolts that hold it on. An also maybe more suspect could be the spark plug cap. If you want to check it roll back the rubber gromet/seal at the top of the plug cap and then unscrew the cap from the wire. Check it with an ohm meter. you should have around 11K ohms. If it is way high or open then you have a bad cap. they are about $3.99 to replace with an NGK model. If you are not familiar with them they have a carbon resistor built into them and over time that resistor can burn out raising the resistance of the spark circuit. We used to see this on old GS's and it would show in a bad idle even after the carbs were spotless etc.
Oh and if you put a new cap on cut about 1/4" off the coil wire just to freshen up the end but not to take so much off you make the wire too short. When you screw in the new one then try to get the screw to hit the center of the wire bundle and screw it down tight and roll/push the rubber seal back down.
Good luck.
