25000 miles later on the VT1100 experiment
Written by mlmiller1959 on 9/29/2010 at 09:55 pm

I guess the advantage is that we know it works and have expanded options for
parts.

Anton,
I sure don't see any advantage. My bike consistantly averages about 45 mpg (43
to 48 and as high as 54) weather in the mountain twisties or on the eway from
60 to 85mph and I didn't lose any performance because of the lower diff ratio
with no extra work. The engine does not have any problems running the stock rpm
all the way up to 75k. Just look at the results Leland has had with all his
bikes.
Fred
