First, if they used their usual hot melt glue, I'd try a soldering gun with the thin slicing tip. If epoxy, how about a Dremel with an abrasive cutting wheel?
Personally, I don't really like the looks of the stock "razorback" with wide canopy. How about revising the rear deck and either a narrower canopy or a bubble canopy?
Whatcha gonna power it with?
