Anyone have any luck putting the head temp sensor from a vapor on a 400EX? The sensor takes the place of the crush washer on the plug but I can't seem to get the plug threaded in. Does not seem like there's enough room to put the sensor in and use the plug wrench to thread it in to place. Seems to be catching on the pointed outer edges of the plug wrench. By the way, what size is the wrench that fits the plug?
