I haven't inspected any of the panels on my VR yet , but most ABS will also have TPS stamped in it . This stands for thermal setting plastic . I believe most if not all ABS is also TPS .
The reason I mention this is because it is possible to ' weld ' , and heat to shape .
This can be done with a soldering iron with a spoon , or flat tip instead of the normal pencil tip ( most irons come with multiple tips ) , or a hot air welder which Northern Tool sells .
You will also need filler material , filler rods also at Northern , or any scrap on the same plastic , even pipe .
I have used this method by heating a screwdriver with a flame , and using it to melt and push the plastic around . Over heating the plastic can make it brittle , so some practice is required .
Out of all the methods listed in this thread , I have found welding to be the strongest .
With the thin panels on these bikes , a combination of methods may be the best approach . What ever works best for you .
