I looked at my manual on my new 700 Grizzly and did not see anything about a break in period. Is there anything you need to do or not do?

If the 700 break-in period is anything like the 660 (obviously I have the 660), the oil is not regular oil. It is break-in oil (what is the difference - perhaps the detergents or the viscosity ?). So you don't want to keep that oil in the engine for too much mileage. From memory, the manual for the 660 mentions to change the oil around 250 kms or 10 hours (or 2 tanks of gas).

The manual also says to avoid driving at a constant speed for a prolonged period. Do not use more than 1/2 or 2/3 throttle (no high revving). What you should do is vary the speed at which you drive.

There are 2 schools of though about breaking-in the engine. The first being follow the manufacturer's recommendations and the other that says you should ride hard to seat the rings properly. I tend to believe and follow the manufacturer.

Varying the engine rpm during break-in and NOT trying any WFO runs is the best way to describe what the factory wants you to do, and that's what I'd follow since it really wouldn't matter what they told you as long as it was true... "Give her ****" could have been said if it was true and nobody would think twice about it... Grizzaholic is right; get the break-in oil out because it will have done its job.

I break my engines in like I plan to ride'em. The Banshee ... I let it warm up & then it's "Balls-To-The Wall" ... never had an issue & it runs great. It also has lasted a long time.

Now I just did a big bore kit in my 660 Grizz ... I'm break'in it in the same way, like I ride it. I let it warm up, then it's slow for a bit & then WFO for a bit. Pull hills fast & hard (depending on the hill of course) ... crawl over rocks & logs, and then WFO again for a bit. I don't baby it one bit.

And here's my reasoning ... I had a Honda 185 I broke in the way you're suppose to ... slow & easy. I had a friend who also had one & broke his in "The way he planned to ride it ... WFO !!" ... The SOB always kicked my rear-end. Or I should say his bike would beat mine. Cause when we switched bikes, his bike (with me on it) would still beat my bike .... the bast%$# !!!

So, bottomline ... I'd break it in the way you plan to ride it. If you do a lot of slow rid'in, I'd definetly throw some WOT runs in there to "Work" the engine a little .... anyway, that's MHO ... but what do I know ?? ... besides, whichever way ya break yer motor in ... enjoy the crap out of it coacho !!! ... WOO HOO !!!

Both Bob and Gunny (lord, please forgive me for saying this) are right. ride it like you mean to for the rest of it's life. Go for a good trail ride. That will give you the variation of the throttle to allow the rings to seat. The owners manual states 10 hours or 2 full tanks of fuel.
