Well I had a deputy friend of mine clock me tonight (2am and no traffic)
at 40mph on my speedo - radar showed 33mph
at 70mph on my speedo - radar showed 59mph

Damm that sucks...lol. I need to get that speedohealer on.

 

thats a huge difference tx, what gears did you end up going with ?

 

just -1 up front so far

 

I have a 06 636 and did -1 +2 and Im pretty sure im about 15 mph off at least. Speedo healer time!!! )

 

I just bought a smaller sprocket. Do you know how much top end you lost total?

 

dunno....but i bet not enough for me to ever find out

 

I have yet to find out how much top end I have lost. I'm having way to much fun getting to the top speed much faster....Oh and the wheelies!!!!
