Well not really first set.... Iv been having my banshee since 2000. Iv ported a few sets but never really put this much time in them. Also I can't take all the credit was me and one of my drag racing bruthas worked on them together. We looked at mine from HJR and his from a local guy ( coony )That builds some fast 350's. One of his bikes qualified 5 out of 17 bikes at Planet sand a few years back. Stock oem frame (not cut on) , stock axle n hubs, stock stroke, stock jug, stock milled head, stock a-arms, 2o over bore, 38 lecterns on alky ran 4.21. So we kinda cheated! Like I said before there's more to makin a bike fast than just cuttn. Where to cut , how to get in there, angles, durations....... Give it up to our builders they work fir the money is for sure. I'll be drag porting for 75% of whatever your builder charges!!! Again kidding. Thanks Bigred
