Riva Ride Plate installation question

[gsxr1300]

i changed my ride plate then went out and tested it and only went 53mph on the candoo, 2017 fxho, now im wondering if i didnt tighten it enough. it was about 68 degrees in cold salt water full tank of fuel, i weigh 190 and my son was with me 60lbs.

What ride plate did you install?

What ride plate was on it before?

What GPS speed would you have expected in those conditions with the old ride plate?

it had a stock 2017 fx ride plate, i installed a 2019 cut by deans. A friend did suck up some shells riding it in a shallow area a few months so I do need to check the prop also, but it hasnt gone that slow. but maybe that combined with cold salt water. Also it was the first time i rode it in these cold conditions.
