Shorter plug?
 

Just a suggestion for the ZDZ factory. Perhaps they could offer their engines with the compact NGK CM6 plug as an option. This would narrow the width of the twins a little to help ease them into some cowls. Yes, I know this would require a different style of plug cap on the ignition, and a different plug hole tapped into the head.

Shorter plug?
 

We have looked at this change. but the net gain was not enough to warrant the change. I'll have another look at this week, just to be sure.

Thanks for the input. We like to hear from our customers about what they think and what they would like to see in the way of new products or services.
