Today I took a couple minutes to look at the very nice 86 swingarm I got from 3 Wheel Drive for my 84/85 pet project to figure out the easiest way to move the dog bone mount rearward around 2 inches to the 84/85 position so the shock leverage ratio is correct. Leaving it in the current position would cause the rear to be much softer and bottom more easily.
I used a piece of manila file folder to show where the new mounting plate for the ears will be, however, I will most likely extend the front of the mounting plate forward around 1 1/2 inches to cover the area where the existing mount will be removed because it will mean less grinding time to finish off that area nicely plus it will give a cleaner overall look. I will most likely have it polished along with the fork tubes and wheels and possibly the shock and aluminum rocker arm if I have one of those made.
I am looking into having the bottom cast iron tripple tree cnc'd out of billet aluminum. This will save several pounds in weight, plus if I do that I will polish both it and the top one. I may reuse the original steering stem if it's practical, however, if it's not I will likely have one made out of chromoly which will save around 40% in weight or I may possibly have it made out of aluma steel if I can get my hands on some.
The bars are aluminum Aero tapered ones, so I could polish those as well but likely won't.
Since this is all suspension related and fairly technical, I was considering asking onformula1 for some advice or maybe even just have him do all the engineering and also make all these pieces for me....or maybe not.
oops....I think I just wet my diapers!
