5500 rpm is my advised
warming up speed.
It's also the maximum speed
I would run a new engine in.
It probably takes 3.5 to 5
miles to warm up, dependant
on outside temperature.

I would not go past peak
power, the engines power will
dramatically drop off above
this (because its a pushrod
OHV engine, not OHC) and
increase engine wear.

If you use the bike above
7000rpm (51mph 5th Gear),
see the
Important Spark Plug
Information (extended high
speed riding part) and
Which Oil Quality to use in the
Servicing page.
