V&H head..?

Not that surprising, but still bad-A. What is surprising is the V&H head. I WANT ONE!
I have seen them for KZ's but never for the eleven.

I noticed the Vance and Hine's head as well. I searched for it, but could only come up with hits for exhaust. I figured the guy just put it in the wrong place. I was surprised that the horsepower calculator tool put the output at 87.13 at the flywheel.

I thought that it was supposed to be higher than that stock. I believe 95?

I wouldn't be surprised if the V&H head was a relic from the days when aftermarket companies still cared about the king of the quarter. Like I said, they made heads for the KZ's of the same period. I haven't heard of Hindle pipes though.

1/4 Mile ET: 11.710
1/4 Mile MPH: 114.000 <<<
1/8 Mile ET: 7.510
1/8 Mile MPH: 102.000 <<<

<<< would think it would still be pulling strong. Only about 11 percent increase last 1/8 mile ?

Guy shoulda got a light weight to run it for him.
No head light, but rest of bike looks like it's there.
730 pounds, bike and rider

i've seen other mags with 11.7 at 114

these are stock bikes, of course they were brand new.

so with a big bore kit and some head work i would expect better
than 11.7
