Hi there , hope this would help . According to the owners
manual
I have quotes '' RUNNING-IN >> ........Running-in maintenace
at
1000 km is designed to compensate for the intial wear .
Timely performance of the running-in maintenance will
ensure optimum service life & performance from the engine
.
The General Rules >>
1. Never labour the engine with full throttle at low engine
speeds.
2. Maximum continuous engine speed during the 1st 1000km must
not
exceed 8000 rpm
3. Increase the maximum continuous engine speed by 2000 rpm
btw 1000km to 1600km. Drive briskly, vary speeds frequently
and use full throttle for short burst only. Do not exceed 10,000
rpm.
4. Upon reaching an odometer reading of 1600km, you can
subject
the motorcycle to full throttle operation. However, do not
exceed
11000 rpm indicated by the beginning of the tachometer red zone .
''
So no need to maintain at 5000RPM, it's a torture to ride the bike
at this RPM, especially at expressway and up slopes.
Moreover the powervault opens only at 6000RPM, where the engine
will sound muh smoother and there's lots more power.
If the vault is closed often, it may choke easily, which explains
for the rough engine sound at 5000RPM, and sometimes slow throttle
responds at lower than 6000RPM.
