How do you test spark plugs?
I just changed mine and i think they may have gone bad. There only 2-3 months old with less than 600miles on them.
Maybe my ride eating them up.
How do I know?
I'm just a new .

What makes you think there going bad. What is it doin to make you think that?

 

Took them out and they were oily.
I changed them. Bike immediatly ran......for 10-15 minutes. Then boged down and I was back to square one.
Turns over and nothing.

 

If your sparkplugs are oily than you are getting oil into the cylinders. Changing the sparkplugs wont help. If the bike is somking blue when running than you are burning oil.

 

If brand new (stock size/heat range) plugs are oily after a couple hundred miles, then you have blown piston rings. This is not a beginners job. But first things first:
1)Check oil quality. Old/dirty oil will have low viscosity and will make your bike run like ****. 2)Check for oil around where your headers mount to your exhaust ports on the motor. Any oil will indicate piston ring failure/blow-by(gaps in rings lining up allowing oil to pass through to spark plugs). 3)If it is indeed oil on your plugs, you need new piston rings and maybe piston. Let me know what you find out.
