I'm sure someone has thought of this, but figured I would pass it along.
I torqued my rocker covers "by feel" when I built my 107. This afternoon I noticed a small oil leak out of the rear rocker box so I tightened it down a little more and considered buying an adapter from Motion Pro. I found that I was able to put my 3/8 torque wrench on the end of the 7/16 box wrench at a 90 degree angle and tighten every bolt with the tank still on. I was off by at least a half turn going by feel.

Hope this helps somebody.
Would the length you are adding to the wrench not change the accuracy of the torque wrench? I would think this would add mechanical advantage... I might be way off on that, but that's how I would picture it.
Unless the adapter or extension is perpendicular to the torque wrench you're going to be way off on your torque values IIRC.
This is a good way to over torque or snap off bolts in unfortunate places IMO.
As stated in my original post, I have the torque wrench 90 degrees to the box end wrench. When you do this, the torque value is correct.
Here are instructions to MotionPro's adapter that may clarify: http://www.motionpro.com/motorcycle/articles/view/2794/adjustable_torque_wrench_adapter__08-0380/

You used your "adapter" correctly. That was never an issue in my mind. I am still curious as to what tool you used to get the values so far off by feel.

Got ya. I had originally torqued a bolt using a torque wrench then tightened it a bit more with a box end wrench to get a feel for how tight to go. I realize I should have done it correctly to begin with.
