	The lines show the fracture ran along the edge, which was reconstituted using ABS cement. As a result, the rounded edge of that corner is gone. It's now a sharp edge, which can easily go unnoticed. The ~~Orange~~ is also significant. That section was gone. Entirely gone. It was rebuilt by making a thin ABS layer, then rebuilding the surface. The rebuilt section was less than perfect, and cracked while back on the bike. This was because the shape it solidified into was not the same as the original shape. After welding the new crack to relieve the stress, it has been doing fine.		The lines show the fracture ran along the edge, which was reconstituted using ABS cement.

	The theory behind the plastic repair is simple. A crack or a break in the ABS bodywork can be bonded back together by welding the plastic together. This can be done chemically, or by heat. Heat is used to make the primary bond, and then the surface imperfections are filled in with the ABS cement. This takes place in several steps.		The theory behind the plastic repair is simple.

	Start by sanding the paint off, to clear out the surface. This makes repainting REQUIRED. You can skip this step and only weld the break from the back. This makes a nice looking, but weaker, repair. If the paint gets into the ABS, it contaminates the bond, and you'll have to sand anyway.		Start by sanding the paint off, to clear out the surface. This makes repainting REQUIRED.

	A hot soldering iron melts together the two sides. Run the hot iron down the length of the fracture from the rear (unpainted side), with your finger on the painted side, moving gingerly up and down the surface. The idea is to keep the feeler fingertip from getting too hot. This is especially important if ~~one is~~ only welding one side. If your finger can't take the heat, neither can the paint. In this picture, both sides are welded.		A hot soldering iron melts together the two sides.

	To state the obvious, the Ninja 250 has a good amount of bodywork. It is ABS plastic, which can be heat formed, or heat-welded. Most plastic repair can be done on the cheap, and without many exotic tools. So, if you are poor, cheap, or have made a terrible life decision to become a grad student making $600 a year, this article is for you.

	The consistency of the plastic can be anywhere from a runny fluid (straight out of the can) all the way to something almost like a thick dough. A half empty can will solidify if left unused. Add some acetone to the plastic to thin out the cement. This can be done to completely solid plastic to make it a fluid again. This also means you have to keep the acetone and stuff away from the bodywork. Spill it, and it shouldn't do much damage right away. It takes a bit of time, and a good amount of solvent before your bodywork does a Salvador Dali impression. Still, don't take the chance.
