I have an '88 DR750 I bought from a friend in Canada. This bike has been modified a bit.
The motor has a custom Shadbolt camshaft, rejetted carbs, custom airbox, and a Staintune muffler from a VTR Honda matched to the OE headpipe.
The front headlight is from a Honda scooter, and the turn signals and taillight are custom made LED's. The seat has been recovered over a gel insert and firmer foam. I have a stainless steel front brake line on it now.
I am going to fit a better front end to it this winter, and see about having a better rear shock made. And relace the wheels.
