    I was just thinking the same thing...sort of. But yes, my dad sometimes did this when heat treating steel. He knew, I just watched.

    is there any reason i could not use a big impact gun? I have a half inch drive northern tool "big boy" that would probably do the job. Just have not seen much mention of power tools and wanted to make sure there was not a reason for it.

    I just spent a week struggling with this, and I want to reiterate that the flat BMW wrench, a hammer, and heat are the way to go. I bought a properly faced 6 point 36mm socket, and came very close to rounding off the left side with it. The fact that the torque is being applied 2" above the nut makes it very hard to keep the socket properly seated on the nut.

    I ended up draping soaking wet rags over everything that might melt, torching the nuts, then hammering on the flat wrench. Even after they 'broke loose', I needed substantial leverage for the first couple of turns. I think someone actually put locktite on the threads...

    Yep, I'd use that. Just make sure the socket has had the chamfer ground down flat as shown in Post #11 in this thread and that it is seated flat down before pulling the trigger.

    Problem solved then! This thing works so good, that it doesnt even seem like it uses a lot of force to do the job. Have been really surprised at several of the things I have tackled with it.

    How is the gas leak problem going? Has that straightened out?

    Yeah, but think there is another problem in there now. Not hitting equal on both sides, left is weaker than right. Swapped plug wires and still left weak. Checked valve gap, and synced carbs using vacuum method. Going to do a compression test...but feeling its in that left carb somewhere. But the flooding issue is gone as far as I can tell!

    Its always something. But at least its a new problem and the old problem is gone. That's what I keep telling myself with my bikes. :D
