The blue drag frame is a 87 and I'm using the wishbone for the front motor mounts,..front is moved out 6".... the silver drag frame with the motor in is a 86, front mounts just go down to the lower frame rails..front is moved out 3"....The backbone has been reinforced above the motor where the headstay would be after a crack developed there. I have ran this chassis for a long time with no other issues. The duner set up is a 86 frame with tubes installed for standard lt500 front motor mounts....front is moved out 4"
All the rear linkage is modeled after a Raptor, using a mix of 660 and 700 pieces. It gets the shock out of the way and so far has cured all the cracking and bending issues I was experiencing with long swingarms and all the leverage points being way up front in the Suzuki design. (I like to run hard through the whoops.....)
One of my 500 full frame duners has made 2 trips this season with the setup, been ridden very hard, and I'm VERY happy with it!
Of course it requires major frame mods to get the attachment points and new swingarms too.
.......good thing for me the guys at Metaltech are into "custom"
