if the man wants to go over 90 mph dont knock him for it. Just because those of you who dont want to go faster....... or dont have the guts to go faster! So what? that wasnt his question! if you dont have an answer, dont comment. as for the speed limiter, i have no clue how they work in trucks and cars, but i do know that on crotch rockets. they retard the timing and add an extra rev limiter in 5th and 6th gears. people have tricked the computers on those to think that the bike is in 4th gear instead of 5th or 6th when it is actually in the higher gears. maybee if your good with computers or wiring you could do the same. i may be way off here just passing on what little i know about speed limiters.
