Dang. You have a 1427 with cams! You should have at least 225 to the back tire. How much do you weigh? How is the bike geared?

forget about doing a compression test, do a LEAK DOWN test. so many things affect a compression test.... compression ratio, valve sealing, rings sealing, cam timing..... a leak down will pinpoint any mechanical problems.

Or you could start with just the basics like listing your weight, your bike's weight.
Also a headwind and hot temps can steal MPH too.
Maybe your tuck sucks.
