Some more info.
Yes, its my part in the pic, thanks 1080 for posting it.
Its alum, first prototype, only thought of this Fri afternoon.
I will use aluminum, its stronger than the stock die-cast material, and wont rust.
I can make it a bit bigger on the knurl, but oiled up it works fine, on mine the spring on rid is almost bottomed, a bit harder to turn but I like the size.
Not done with it yet, I will change the flat end to a radiused bump or a U groove, or several choices.
Price will be 10.00 or less, with Quantity discounts.
They can be rolling out the door by end of next week, along with the starter and tach plugs, and Exhaust clamps..
