I bought this pan at Walmart, its 7.5" by 7.5" and it fits great. It may work on the Pioneer 1000. Huck sent me a picture of a funnel that made me try this. Thanks Huck.
Not sure if it’ll fit in this space or not, but in the past I’ve cut open a 5 quart oil bottle to use as a drain pan for tight spaces. I imagine the 1 gallon jugs from Honda would work well for this.
The frame is in the way. I always removed the skid plate. I made an oil deflector out of an old motorcycle license plate to keep the oil off the frame and wiring harness.
My buddy at the Honda shop found this pan at Harbor freight. I clipped the corner for a better fit. It is shorter so the oil will drain. I'm doing an oil change every 2 to 3 weeks.
