BTW, how did you reverse the spring?  Can you just bend them around to the proper shape?  These springs on this
BMW throttle seem to be pretty stout.  I don't think bending them into shape would be trivial.

I modified the spring on my TWM; I think I cut off about 1/2 a turn.  Set it
up so a throttle lever disconnect would result in about half open throttle
(which may be about 70% power).
