pfrederi   18,986 #6 Posted yesterday at 01:08 PM You have the Breakerless Ignition system. When it works it is great but when it dies you will be looking at switching to battery points. Make sure you NEVER apply voltage to the terminal on the bottom of the coil. Use only ignition switches with an "M" terminal (magneto type) 2 Share this post Link to post Share on other sites

In fact if it's still working, I wouldn't remove it.  I have a couple Breakerless they are much nicer than the battery points or Mag points. No points to ever clean or adjust and timing is always spot on!!!  If it fires and you still want to get rid of it I would buy the trigger and coil from you . 2 Share this post Link to post Share on other sites

Needs a bore job Just not sure to go .010 or .020 over.  That is .009" over the limit and .012" over nominal. You will be lucky to cleanup at .020" over size. Since your measurements sound wrong to me, take it to the guy that will bore it and get his opinion and then get the piston he recommends so he can fit it. 1 Share this post Link to post Share on other sites
