Nikasil is very hard and the media will do no damage to it.. However, I don’t tend to blast the media directly in/ at the cylinder bore...

Check the pulse coil gap... also ohm readings on a stator can be misleading... check the peak voltage...

Reply to Old Honda CT90 Question 7/16/2021 1:50 PM

Is there any scoring on the bore that the bucket rides in? I’d pull the spring and make sure the valve isn’t too tight in the guide as well...

Reply to Valve bucket emergency 6/28/2021 11:13 AM

Is the bucket getting stuck in the head or is the valve sticking in the guide? Were the guides replaced??
