The rings etc were properly installed, but I cheated and sanded the piston's scores and smears out of the side of it with emery cloth. Not such a good idea, now that my buddy's 8 year old runs the s*** out of the 4 wheeler it's mounted on, it has developed an audible piston slap.

I doubt that is the problem. Three things will cause an oil pumper:
1. Cylinder worn beyond tolerance
2. Cylinder not properly honed
3. Oil Rings improperly installed
Take your choice.

"Lunytune exclaims:

this renews my faith in the midsize 80-120-150 scoots. I'm still thinking of transitioning from the 250. It's just too heavy.

I wasn't going to say anything further on this topic because I don't want to evoke the wrath of the 2-Smoke Poreece. :shock: But, I'll leave it at this:

The CH80 has been the subject of ridicule and scorn - for its questionable styling (a Jetski got drunk and had its way with a ShopVac), ABS clad frame, and allegedly slow acceleration. But few owners surveyed have complained about engine reliability; on the contrary, reliability is the Elite 80's hallmark. The scoot is a work of urban transpo genius, arguably among HondaSan's best and most enduring designs.

It is what it is, and what it is - is a d*** good handling, in-town scoot. 8)

YMMV.

Greetings:

The rings are just one of the places where oil can exit the engine. Valve guides and seals are a common issue on 4-strokes. Ask anyone who's ridden a late 70s Yamaha 750/850 Triple. Under high-RPM and hot conditions, the oil escapes discreetly out the tailpipe with little/no smoke. Mine used a quart for every 500 miles until I re-built the head.

Ole Sage Wheelman, Touche. I didn't think about valve seals and guides, and I own a 318 Dodge and should know better. :? Yeah, no ribbin' there.
