if you want to get your speedo more accurate with lil modifications next time you replace your rear tire go from a 180/55 to a 180/60 thatll take most of the optimism out of your speedo. also about the windscreen getting in the way when you sit upright, even the 04/03s are like that and a double bubble will fix that problem.

 

also heres something kinda dumb kinda funny. my cars the opposite of bikes, instead of being optomistic my car (72 firebird) is a pecimist. when im going 25 it tells me im going 5 [&o] i got a ticket in it for doing 70 (thats what they clocked me at, two secconds before that i was going 130) in a 55 zone, if it werent for the fact the dick would have probably giving me a fix it ticket i shoulda told him he was lying that my speedo only sad 50. it was on 110 before i slammed on the brakes cause i saw two chp bikes on the side of the road so that meant i was goin 130+
