The Grandma Break-In Procedure
Yes, I know what the manual says. I've read all of them over and over again and they pretty much tell you to feather the bike during the break-in period. Only the manual for my Dad's 2000 Dodge Intrepid said to bag the engine from low RPM to redline and then let engine breaking bring it back down to reasonable speeds. At the time, I thought that this was severe, but the my Dad still owns that car and it has never been in a shop for engine problems and does not burn oil (*knock-on-wood*).
Proper (Undocumented) Break-In Procedure
If you follow the break-in instructions for your bike, you are going to hurt the bike more than help it. Anybody that knows anything about bikes recommends taking the engine up to 10,000 RPMS (under load) for the first 20 miles to achieve a good seal. Change your oil in the 25 to 100 mile range as there can be a significant amount of metal shavings shred off from the break-in procedure.
Few of us who have worked at dealerships and had a chance to talk with factory representatives tell you to "...break it in like you are going to ride it". The best place to break-in a bike is at a race track because that's where you will push the bike hardest.
Street Break-In Procedure
Motoman's website (http://www.mototuneusa.com/break_in_secrets.htm) has great information on proper break-in and the engineering reasons behind it. You should spend a few minutes reading it, but here is a summary of how to break-in a bike on the street as provided by Motoman:
- Warm up the engine completely.
- Open the throttle hard in 2nd, 3rd, and 4th gears.
- Alternate between short bursts of hard acceleration and deceleration.
- Do this for 200 miles or so.
Is The Manual Wrong?
So why does the manual ask to take it slow? Liability. They don't want to be responsible for your injury or death in case you are a noob and have no experience riding taking the bike to 10,000 RPMS with equally high speeds trying to break-in the engine as guided "by the owner's manual".
