Technical Tips
The Problem With "Easy Break In" ...
The honed crosshatch pattern in the cylinder bore acts like a file to allow the rings to wear. The rings quickly wear down the "peaks" of this roughness, regardless of how hard the engine is run.
There's a very small window of opportunity to get the rings to seal really well ... the first 20 miles !!If the rings aren't forced against the walls soon enough, they'll use up the roughness before they fully seat. Once that happens there is no solution but to re hone the cylinders, install new rings and start over again.
Fortunately, most new sportbike owners can't resist the urge to "open it up" once or twice,
which is why more engines don't have this problem !!
An additional factor that you may not have realized, is that the person at the dealership who set up your bike probably blasted your brand new bike pretty hard on the "test run". So, without realizing it, that adrenaline crazed set - up mechanic actually did you a huge favor !!
Here's How To Do It:
There are 3 ways you can break in an engine:
1) on a dyno
2) on the street, or off road (Motocross or Snowmobile.)
3) on the racetrack
On a Dyno:
Warm the engine up
completely !!
Then, using 4th gear:
Do Three 1/2 Throttle dyno runs from
40% - 60% of your engine's max rpm
Let it Cool DownFor About 15 Minutes
Do Three 3/4 Throttle dyno runs from
40% - 80% of your engine's max rpm
Let it Cool DownFor About 15 Minutes
Do Three Full Throttle dyno runs from
30% - 100% of your engine's max rpm
Let it Cool DownFor About 15 Minutes
Go For It !!
