I keep thinking about the post where the guy was apparently running smaller chain sprockets. What would be wrong with a 12/48 = 4 – 1 combination. On 2 cycles they use both 9 and 10 tooth engine sprockets and turn 16,000 RPM. Surely the load would be much less at 6000 RPM? I don't know how much, maybe a 3rd? Maybe less? All we would really need is a sprocket carrier to fit the smaller sprocket. Maybe try it with 219 chain?
Some advantages; less reciprocating weight, slower chain speed, more ground clearance. I see it coming
