How common is the 10mm X 1.0 thread on most metric bikes? I think, without checking my manuals that is the proper thread for the spark plugs on our and a lot of others right? Some are on the forks if I remember right also. Looking at something but want to check on how much it might get used. Mike

A few out of the dozens of water temp gauge installations have reported leakage at the adapter. I think we have found a cure. I sell the adapters with a 18mm crush washer. The problem occurs where the inside diameter of the washer meets the outside diameter of the adapter. There is a recess machined into the adapter which allows the washer to slide over to one side which will not seal. http://i672.photobucket.com/albums/vv87/dawarren77377/Bike%20shots/waterseal3.jpg?t=1263574491 To solve this issue place a 1/2" ID X 3/32" thick o'ring between the adapter and the crush washer. Make sure the tabs on the washer face away from the o'ring. With the o'ring in place against the washer, the tabs should still engage the threads. http://i672.photobucket.com/albums/vv87/dawarren77377/Bike%20shots/waterseal4.jpg?t=1263574679 http://i672.photobucket.com/albums/vv87/dawarren77377/Bike%20shots/waterseal5.jpg?t=1263574858 http://i672.photobucket.com/albums/vv87/dawarren77377/Bike%20shots/waterseal6.jpg?t=1263574887 The o'ring alone would work if the adapter had a groove machined in it to prevent the o'ring from squishing out (like the water jacket plug removed from the cylinder head). The washer holds the o'ring in place and the o'ring holds the washer centered. http://i672.photobucket.com/albums/vv87/dawarren77377/Bike%20shots/waterseal7.jpg?t=1263574917 The o'ring is available at most hardware/home improvement stores. The one I bought was a #35 o'ring, however all o'ring manufacturers may not use the same number. If anyone who has bought a kit from me needs either the crush washer or the o'ring, let me know. Also, I have received a request to announce what tools I use to remove the water jacket plug and install the adapter. Most use a standard 10mm "L" or Allen style wrench for removal. A 10mm hex bit/adapter to 3/8" drive works well for plug removal. You can put a breaker bar on the hex tool for leverage. I sawed one inch off of a 10mm "L" wrench which I can use a 10mm box wrench or a socket and ratchet. It is important to use a hex that is in good shape. If a rounded hex tool is used and the plugs is damaged, you have problems. I use a 7/8" or 22mm socket with ratchet to install the adapter. If I have a leak or need to tweak the adapter after it is installed, I use a tubing wrench. You don't have to buy an expensive tubing wrench. I bought a $3.00 combination wrench at a pawn shop and ground a 1/4" slot in the box end. This slides over the thermocouple tube easily. I also use a 5/8" (16mm) tubing wrench for the thermocouple nut. Cheers, Ponch
