I just checked my spark plug yesterday, but when i was removing the electric plug, I broke the security pin of the plug, for now, I maintain the plug with a Tie Wrap and even if I try hard i can't move it with my hand, both the plug and tie wrap.

But in order to have a safe riding (yeah, because if it goes off, i will have a cylinder not working..and it's a track bike ) what tool I need to remove the pins connectors from the plug...you don't find this everywhere.

I'll post a pics later tonight (i'm at the job) because I have hard time to explain the problems...

Thanks you

 

If it it is the plug from the harness to the stick coil you will need a pin removal tool. Sometimes you can get away with a very small screwdriver but I would you the tool. Post some pics so we can get a look at it.

 

Yep it's exactly that, i will try tonight with a small screw driver, i didn't think about this option yesterday.

Here the pics:

 

Yea small screw driver is all you need. just make sure you replace that piece.
