[quote="Andy"]14/42 on a 1994 MC28 gives 150kmh @ 10,000rpm. That equates to 120kmh @ 8,000rpm (74.5mph) on a standard gearbox.

Thanks Andy,

A measure check this weekend confirmed I was a bit off on my speedo settings. The tire circ. is 1899 not 1924 as I had originally calculated. Dam Metric to Std. conversion.

I hope to test later this week and confirm with a GPS for accuracy. I am thinking about trying a 15t front sprox to drop the RPM a bit. Any thoughts?

And yes, I was talking US Gallons. The tank spec. is 16L but is that with or w/o reserve? My speedo setting would have thrown my calculations off too but even at that, 34 mpg isn't horrible.
