Yep, that is the idea for the DIY and do not have the tools or want to drill and tap there engines.

When I convert them for customers I drill and tap threads to relocate the sensor, Some of the times I only have to do it for one screw.

Below is a picture of a Horner 180cc I did for customer and only had to drill and tap one hole, Could use one of the existing holes. The black screw you see was put in one of the existing holes just to make sure there was no air leaks from it.
