Dyno Day! - *video added*
I finally made it to Clifford Cycle in Omaha for the dyno run I was supposed to do last Thursday, the afternoon I wound up going to MAM. Here are the results.
I'm pretty happy overall. In past tuning and dyno runs on other bikes, I've learned not to "chase a number" and that Clifford's dyno reads a bit more realistically than some; the figures are more than acceptable, considering.
The tech told me stock FZ1s typically pony up ~118 on their machine, so 127 peak hp is nothing to sneeze at, a 9 hp gain with much improved fuel metering and driveability over stock.
It would appear the a/f ratio is right in the range it's supposed to be but for a pronounced dip early on. The tech seemed to believe I could clean this up in going down one main jet size, but I'm going to talk to Ivan before I change a thing ... the bike runs beautifully as is, makes perfectly linear horsepower, and stomps out 75 ft-lbs torque at a fairly low rpm given the nature of I4 engines and their penchant for spinning. For comparison purposes, my 954 made similar power, but 8 ft-lbs less torque. (But it is a lighter machine, thus, accelerated a little harder.)
Weather wise, it was cool today, only about 65 degrees, but still pretty sticky at 75% relative humidity (the norm in this part of the country). Omaha's about 1,000 feet above sea level, for the record.
