Changing the exhaust alone will NEVER alter mph/rpm relationship.
STOCK EXHAUST: 6th gear doing 70 mph = 6500 rpm
AFTERMARKET EXHAUST: 6th gear doing 70 mph = 6500 rpm
LEAK IN EXHAUST: 6th gear doing 70mph = 6500 rpm
Only thing that can change the relationship is different sprokets and/or clutch slippage. -
Yeah , didn't we JUST have this conversation ?

The real question is why is he spinning 6500 RPM to hit 70 mph? I hit 70 around 5200 RPM... What's the bike's sprocket gearing?

all stock besides the exhaustComment

i notice with mine cruising around 65 mph my rpms are around the 6,000 range which I am starting to think there is some type of aftermarket sprocket or sprockets on the bike. any easy way to tell if this is true besides counting teeth??

Look on the Sprocket...should say something like 46T, 45T, etc the T stands for teeth...may be covered with gunk so you may have to clean it off...Originally posted by macgyver

This is a long shot. but if you tires are way low on pressure that can change the rpm a couple hundred rpm at the same speed. Or if you recentily changed the tires.
My old yamaha pulled about high 50s at 5000. I put new rear tire on it and it would be going 67-68 at the same rpm. Plus the old tire wouldn't hold over 20 psi. LOLComment
