Cylinder Plating?

[dave]

Heh--regulator/rectifryer.
Does the VFR have a primary chain between the main crank and the tranny? Most V-twins do. The V-four is not as unbalanced as a V-twin, and do you know if the VFR has electroplated cylinders bored into the top half of the VFR's crankcase?
Your VFR is not burning any oil at all?
The wear was the leading and trailing (front back edges) of my VTR's cylinders. They were more than TWO millimeters out of round--pretty much zero compression.

My VFR does not use a primary drive chain between the crankshaft and the transmission. The cylinders are integral with the upper crankcase, but they are not electro-plated - I know this because I just checked, and Honda sells over-sized pistons for it. From the view in my service manual it appears that the cylinder liners are pressed into the upper crankcase, and I assume that they are probably cast iron. I change the motor oil every 3,000 miles and the level have never gone down between oil changes.
