I have 75% or more of the parts to put a Blaster motor in an 86/87 chassis. I'd also like to run a TRX450 swinger with linkage suspension. I have an 05 shorter swinger 450 setup...
When I had a Blaster for my "EX", A FMF pipe, lid off and jetting really woke it up.
Simple air cooled reliable motor as well and a short kicker.
I guess it's all in what you have laying around, lol.
