Recently been given one of these by a mate as he has changed to a SIP speedo, so planning on fitting it over the winter. I think this image was posted on here a few years ago, but is the route I will be going down.Basically goes under the suppressor cap with rubber (assuming a peice of fuel pipe?) holding the sensor in place on top of the spark plug. Hope this helps and thank you to whomever posted the original picture.
