Here is an interesting experiment that I tried when I was much younger there, was an road with a long straight leading up to a mild S bend and another long straight away from it, followed by a gentle curve to the right then down a hill, I loved that S when I first rode it, it was an 70 mph corner 71 one way and 69 the other any how like I say I loved it so practice, practice ( it wasn't too traveled at the time ) so my speeds went up and I got to the point where I scared my self and I backed off a little bit at the end of it I was up to about 80 one way and about 82 the other (the smiths speedo on the Triumph Bonny was not that accurate, it took me awhile to start using the tach and gearing to figure top speed ) it was a corner if I thought I was getting a little rusty I'd go back to again and again.All of this is a lead up to say that I knew the corner well and could tell you if I was driving it well without looking at the speedo any how I drove it after a couple of beers and felt I'd cut time off the corner, so next weekend back tried after one beer, not sure so back to the pub 1 more, yes definitely faster, so how about 3, not sure, thought about it all week, one of the guys in the barracks had a stop watch so my buddy borrowed it and away we went to try out the theory that a beer will smooth out rough spots we get to the corner, buddy hops off we arrange signals to figure things out, try it twice to set median, good day averaging 83 through fast side of corner off to the pub a beer back to S try it again, 80 try again and again 80 is best I came do, back to pub another beer back to S bend 75 consistently no matter what I do, push it to where I scare the #$%* out my self no better than 75 so back to the station where the "Wets" is now open many beers, think about it then and over the next week, final conclusion, no matter how it feels, any thing that impairs mental clarity costs time and skill, never drove at high speed on a bike again after drinking or any thing else, and yes I know, not a proper test not enough fail safes built in, But again But.
