120mph on “Dream-o-meter” = ?

Stock bore is 69mm. Most common big bore is 73mm. Porting is not as easy to check without a stock barrel to compare to. I would think someone here would have a stock barrel they could take a picture of once you get yours apart that you could use for reference.

Thanks BornYamaha I will measure the cylinders when I get it apart this summer. I appreciate the info. I will throw some pics up here when I tear it open too. Thanks again

My '01 SRX is about 12-14 MPH off dependent on surface conditions. 120 speedo = 106 GPS

That's weird, my gps showed 116, when the speedo showed 126. (SRX). I have an european srx and the speedo goes to 200 kph, which is 124,3.
