Thank you for your kind words, gentlemen.
I am enjoying the extra power from the fresher, larger engine. I am also enjoying the wide ratio, 6-speed transmission. First gear is lower than the Zong's original first gear, and sixth gear is higher than the Zong's original fifth gear, providing a
very nice overdrive gear.
The Yamaha engine was clean as a whistle, and obviously had low mileage based upon the tightness of the connecting rod, and very little wear on the clutch basket. I also found very little carbon deposited on the piston and cylinder head. I do believe this Yamaha engine is good for another 70,000 miles.
