Buy a tach!!!!!!!!!
well if this helps 80mph on my 09 ultra is below 3000rpm in 6th and would hazard a guess that the magic 100mph will be below 4000rpm (not seen 100 yet on the ultra )
Glider, was unable to get this link to work. Anyone else have a problem?
Until things change, they stay the same!!
