With the strange 'too warm to hunt' weather here in December between the holidays. I finally got going on the long put off top triple clamp for the speedmaster that would fit isolators like the thunderbird uses. No longer having balancing shafts in the motor makes handlebar isolators seem like maybe a worthwhile thing to have.
I started out with a 12x5x1.25 inch bar of 6061 aluminum (that I bought 3 years ago). After whitling away most of it, I was about 85% finished when the cold weather returned and stopped work for a while. I have to order a 1/8 inch slitting saw to cut the clamps and a little more light weighting left to do. Then wait for it to warm up again.
I have a set of new t-bird isolator rubbers and will use a t-bird riser spacer to adapt my HD duece risers to the isolators. It needs to be loosely assembled and then I can calculate the optimum length for the inside steel isolator tube based on the motor turning at 4000 rpm.
Not sure of the finish that the clamp will have. Could polish, or could tumble and hard anodize to look like the OEM, could anodize a bright color, even chrome!
