I mounted mine direct to the frame using the engine mouts supplied, but I also placed a peice of inner tyre tube around the frame, this was to surpress vibration and ensure a more secure clamping grip to the frame, these other alternative mounting methods are usually to assist for over size frame styles, if you use the t shaped mount it will make your engine sit higher in the v frame, and this could cause other issue with fitment, see how you go, Im sure other memebers will leave posts for you
