I’m not 80 yet, I still have a few years to go.Me as a German i can tell you from own experience.
Matter does not disintegrate over 80mph.
Although i was driving a porsche 180mph when i was younger, when a bird crashed into my right headlight. That led to the disintegration of matter. But this is another story.
Only, when the driver is over 80 it comes to problems.
But back to the question. When did you last time change your fuel filter, if your truck has one. Not all gmt800 have one, as far as i know. As well the air filter can be clogged.
I would start at the simple stuff.
I will say I no longer ride anything with only two wheels on the pavement. I hate to think what would have happened if a bird has hit my helmet while I was moving at 152 mph back in the day.
