I have gone way passed 5500 rpms a few times since 350 miles on a new bike, How bad is this?

 Its good to vary the RPMs but not go too hard on it...

Did you run to the red line? Generally its not a rule, you should be no worse off than if you didnt do it  O0. Its more a safety precaution to ensure all parts "seat" and wear properly.

As long as you see no evident damage, you should continue w/ normal break- in. vary your RPM as much as possible.  :thumb:

if you go over 10,000 rpm, you risk floating a valve and killing the engine. Your warrantee won't cover that.

CHECK YOUR OIL NOW.

Do you know the proper way to check your oil ? No ? OK:

Get a red sparkly thong (used is best) and either park your ride on flat level ground, or sit on it, same kinda ground.

Unscrew and wipe off the dipstick.

Replace the dipstick in the case, WITHOUT SCREWING IT BACK IN.

Check.

Repeat thrice.

In the hashes = good, ride on man

Above the hashes = bad, will effect shifting and possibly blow a seal somewhere

Below the hashes = bad, could kill your motor by starving it of oil :(

Do you know how to check your chain slack ? Get to it !

Check your air pressure ! Daily !

Ignore all except what the manual tells you.  Keep your warranty intact.  Vary Rpms and keep in Rpm range to each service.

Based on some of the talk around the Internets, I'm relatively convinced that the low-rpm recommendation is a liability thing (they don't want you to hurt yourself on a new and unfamiliar bike).  All the reports of hard break-ins seem to be it makes no difference, or it's better.  I've had two identical 2001 GS's, one that was broken in softly, and one that was ridden hard (both by previous owners).  The one that was ridden hard I think has more guts (better compression/power/whatever).  It's certainly not damaged and it's running fine.  So I would do whatever makes you feel good, whether it's following the advice in the manual, or having as much fun as you want.  (They can never know what RPM you ran to void the warranty.)  Go look up motoman, some people think he's a genius, some people think he's nuts.  I won't get involved in that discussion, but read up on some of his arguments and see if they make sense to you.

And if you've already ridden a couple hundred miles, it doesn't matter what you do after that.  Most of your break-in has already happened.

"Its a safety precaution to ensure all parts "seat" and wear properly." Also to ensure that there was no error in assembly at the plant or at the dealer  :thumb:

Its not a gimik or something to make you ride slower... Its needed to seat and wear all parts correctly.  :cheers:

And like I said, its not gonna kill the bike if you go over, but you should follow breakin properly to avoid problems down the road  :cheers:

Sounds more like a CYA for the manufacturer... which does not mean it is the best way to break in a motor.

Varing RPM is going to do more benefit than a constant.
Common sense in not very common.

If there was a manufacturing error that's worsened at high RPM, I'd rather find out right away and get it replaced ASAP (especially while the warranty's good).  I don't want the engine that barely passed QA off the assembly line, I want the good one where everything was built right.

thanks everyone, i know normal maintainance things. But in out plane engines they suggest break in at full throttle for the most part.
