i have a speedo healer on mine diled in to dead on and mine goes to 140 pretty well but i couldnt get much more out of it

 

hmmm, i tried topping mine out first week i had it, speedo said bout 163 before i let off gas. I know its round 6mph off....all yours seem slow. Also ran mid elevens at track

 

I get up around 150 on a regular basis and mines is stock.

 

i had mine around 140 trying to follow my brother on his busa before... 240 6'0"

I don't know how far off my speedo is but I've had the needle at 172mph before. bike felt like it had a little more left in it. Only thing done to the bike that I know of is a K&N filter and Jardine RT-1 slip on.

 

well I did the test... me and a friend ran on a highway.. my bike hits 155 mph which mean 248 Km/h... after pull over we checked gps measurement.. 231 km/h was the real speed.. about 7% off.. i think it's pretty close.

up to 150 km/h everything pass so fast that nothing can save u jejeje

 

i was clocked on radar at 169mph on my 98 f3 by one of my mp buddies when i lived on edwards afb in cali. long straight aways out there in the desert. But it was far from being stock. lite airtech body,jetted,powerpak,coils,full yosi race pipe,-1 tooth in the front,190/55/17 rear tire

 

I've got the same upgrades as you on my 96 CBR600 F3, and my speedo matches those roadside radar monitors within 3 MPH. . .

I'm 6'3", 186
