I will have to try that! Are the speedos always that far off that it can change 15+mph? I could see maybe up to 5mph off give or take but thats about it

Stock speedos at a MINIMUM are 8% off.... Some are 10% off... And the error is not always linear.....meaning the faster you go, the more the speedo gets off....

GPS is the only way to know... even calibrating the speedo with a Speedo Healer and calibrating it to a GPS still doesnt always get them dead on at all speeds... They may be dead nuts even with a GPS at 70 mph, but they will get off at high speeds...

I have speedo healers on both of my bikes and the speedos are calibrated to GPS at 70 mph...

My 1000 digital speedo stays pretty close, even at 177 mph on GPS the speedo is within 2-3..
170+ on a 600


My busa at 198 mph on GPS is indicating 207 mph... Thats AFTER calibrating it at 70 mph... It has an analog style speedo so I think those have more error in the high end of the range.

BMW has been the only manufacturer that offers the most accurate speedos, i have hit top speed at an indicated 186.3 mph at 12,000 rpm, after that the rpm keeps climbing but the speedo was stuck at 186.3 and gps indicated 191 mph top speed

My old GSXR used to indicate 168 all the time. In reality it was about 145 with the gearing

Almost any top end smart phone these days are powerful enough to be a complete data logger, drives the ECU and perform traction control at the same time with the proper interface and software.
Do you have to hook up any type of interface to your bike for the dyno reading?

Yeah...it was good times.. I'm glad you and Roy made it!

I will avenge myself eventually... I had a LOT more in it... Now with the hacked ECU and 11,300 limit, I should have 240 mph in it with some boost cranked in it...

MAYBE when they start running a full mile at the Houston Mile, I may try my luck.... I won't be running the Texas Mile as long as they run it at Beeville.....I might even take the mirrors off next time...
