1/4 mile times

What was your mph? Horrible start, or one plug wire fell off? Going uphill on a 12% grade? Andre the Giant on the back dragging his feet the entire way? Stopped for a coffee and doughnut at the 1000 foot?

Something appears to be up with the app, with your bike, or both.

I ran a 13.9 on a mostly-stock '81 GPz550 at a run-what-ya-brung dragstrip. It seems like an 1100 should do a little better than that.

Ok here's the numbers from what I saved

60' 3.807 @ 33.06 mph
330' 7.849 @ 69.08 mph
1/8 mile 10.788 @ 83.68 mph
1000' 12.843@ 89.57 mph

1/4 mile 15.837@ 96.79

This was the 1st time I had done any kind of launch like that,
if I was going to try another run would I have to drop air pressure in the rear shocks and tire?

I think your phone app. is junk those numbers are no where near what your bike should run.
