I read somewhere back a few days ago before I moved and lost my internet connection for a few days that one quad would run faster than another quad of the same type and model depending on how they were broken in. So what's the story with that? How do you break one in so that it goes faster than another. I'm on mile 29 and hour 5, so I've got a while to go in my break in. All the dealer told me was not to let it idle for long periods, and try to avoid full throttle, oh and also ride at different varing speeds and throttle settings. So what do you do different than that before the 100/20 service?

 

Motoman will tell you why you want to break it in hard! Sorry, to late for you though....most folks just can't resist riding around on a new machine, and they miss that first curcial few minutes for a proper break in: http://www.mototuneusa.com/break_in_secrets.htm


You should also do an oil/oil filter change very early on (like at 1 or 2 hours!), to get the shavings left over from machining out of there quickly. Same goes for your front differential and rear gear case. Run a petroleum based oil during break-in, then you can change to a synthetic after that.

Do not neglect the 20 hour valve adjustment!

I'd say make sure the oil level is correct, don't lug it or bounce it off the rev limiter, and don't baby it. Put a reasonable load on the motor so the rings will have the pressure and heat they need to seat. Also, no synthetic oils, and do the first oil/filter change and valve adjustment on time or early...

Have fun with the new machine.

 

ride it like you stole it!!

 

Fortunately I live in a very mountainous area with lots of wicked hillclimbs (Reche Canyon). I break it in by doing hillclimbs! I warm the engine up thoroughly, then blast up a long steep hill, turn around at the top and come down it under very heavy compression braking. I do that three times, then park the bike and let it cool off completely. I do that again, each day for the next several days. This breaks the rings in real nice!

After that, I just ride normally but taking it easy, and this is intended to let the bearings and other things break in completely....

 

break it in like you will ride in the future. ride the crap out of it

 

Almost everything that was said here is correct, the only suggestion I have that a lot of people are not formalized with is RPM within the first 600 miles or 30 hours... Try not to keep the same RPM all the time. You shouldn't have a problem doing that unless you are riding roads or something

When a brand new engine starts to run there are no markings on the cylinder, if you run at a constant RPM while it is new you will etch the wall of the sleeve and contribute to later malfunctions. All Sleeves and Cylinders have this etching but if you vary your RMP speed the etching will vary without a catching ridge within the motor.

 

ohh and no you don't have to baby it at all [img]i/expressions/face-icon-small-wink.gif[/img] ride that biatch! [img]i/expressions/face-icon-small-happy.gif[/img]

The best engine builder I know says those things "absolutely LOVE coming downhill under engine breaking when it's being broken in, absolutely LOVES it," and that's a direct quote.
This guy is the premier motor guy for many miles around. I suspect he didn't get that way by spouting nonsense. So in other words, the above advice would seem to be spot on!
Cheers!
