HI All, two not so simple questions.

How do you mount these dax engines? (the KTMC 9HP) Seems much better then the FM80s

The KTMC is a much better engine but you do have to fab up your own mounts by welding tabs or brackets to the frame so the engine can be bolted in... some people have successfully used sections of tubing split in half and clamped to the frame with all tabs and brackets welded to these sections of half pipe, I won't recommend clamping the half pipe sections with radiator hose type clamps, but T bolt clamps are much more durable and they come in all sizes. This would be the ideal way to clamp the sections of half pipe to the frame. This also makes installing and removing the engine fast and easy if the need ever arises since everything is welded to the half pipe instead of the frame, which would also make the engine easy to transfer to a different bike later on.
