Lynn,
I have one of the newer Triumph Bonnevilles. No Whitworth threads but it does leak. Does that count?

Thank you all for the info. I am not sure where I would be without all of you. Lynn, thank you for asking about my progress. I did have an exciting weekend just past as I put the track back on after about a 1-1/2. I just need to get the engine running right. Some seats and armor might be a good Idea too.
