im lpretty good at fabbin, and the blaster swingarm looks to be alot easier that some of the bikes ive done. theres a nice straight stretch of area in front of the shock mount. cut it there and add what ever addition you want and slug it, weld it back together and move the shock mount in relation to where you get the hiegth you want.im not sure of the geometry for the shock placement. but the act of stretching the swing is pretty simple. whenevr ive done them in the past, ive made a jig to hold everything in place and straight till its welded up.you could pick up a stock swing pretty cheap and give it a try.that way you dont hack up ur own. but its a great learning exper and well worth saving the 2 bills an aftermarket would run ya.but if the fabbin isnt your deal, yb200 was mentioned on here as a good source.
