I fire mine up for the first time and let it run just a few minutes. Then I let it cool for a while fire it up again let it idle for 5-10 minutes with a fan blowing across the radiator. Then take it up and down the street for 5-10 real easy laps then 5-10 getting on it a little. After that I ride it fairly easy for an hour or so then go to normal operation.

Riding it hard from the very beginning is wrong but I won’t argue about it because I don’t care if people who know it all break their quads in correctly or not.

 

Me either, but I had a few alchoholic beverages last night so may be that made me rant? I came back on here and was like geez, my dam keyboard is gonna be wore out! My apology for sounding like a d!ck last night. Happy riding everyone![img]i/expressions/face-icon-small-smile.gif[/img]

 

This guy is totally correct! Check my previous post![img]i/expressions/face-icon-small-smile.gif[/img]

 

Some interesting theories on break-in, no question about it. I've worked on different kinds of engines for over 20 years, everything from chainsaws to diesels putting out over 9000 hp, and I've never broken an engine in the way some people are recommending. I'm not saying they're wrong, I'm just saying it's a radical departure from what I'm used to doing and seeing.
All I've done is start the engine, let it idle only long enough to make sure there are no major problems or leaks, then start increasing the load slowly, adding rpm as you go. A typical break-in run on a diesel gen set lasts anywhere from 15 to 35 hours, with the load reaching maximum at the very end of the run. I know that's not achievable without a dyno or some way to control the load accurately.
In the real world of quads, bikes, and cars it's a little tougher, but the overall effort is what matters.
If you can keep the idling time to an absolute minimum (excessive idling will glaze cylinder walls and cause a poor sealing surface), avoid full throttle extended runs, and try to vary the rpm and load as much as possible over the recommended time frame, I doubt you'll have any problems. Personally, I baby the engine for the first while, avoid lugging it down at all costs (it's better to have rpm than not), accelerate gently, and allow it to warm up slowly under gently increasing load. I've yet to have a seized engine or a bad oil-burner, so something must be right.
The main things are to avoid too much idling, and avoid lugging it badly, and drive it like you love it for the first while. Time enough for tormenting the beast when it has a few more miles on it.
