Not saying I agree with it and not saying I don't, but here is the site I think you might be looking for. http://www.mototuneusa.com/break_in_secrets.htm Sorry, don't know how to make it so you just click on it.

 

That is a very interesting link. It makes sense and is well presented.

Thanks.

 

Introducing a load to seat rings etc, reapeating heat and cooling cycles, and generally giving your engine a taste of what it will be getting is a GOOD thing. Running it 10 minutes and then pegging the throttle thereafter is NOT a good thing. The diffs, (trans on cars), and many other parts do NOT seat in the first few minutes as the rings do, and running the crap out of the engine the first time you have it out is not a good idea. As I said, you guys can do what you like...your engines won't last as long but I dont really care[img]i/expressions/face-icon-small-wink.gif[/img]

As for nascar and racing engines - yes those guys get on them right away. They also have big sponsors that rebuild the engines every race or two so they don't care about longevity... it's your wallet[img]i/expressions/face-icon-small-smile.gif[/img]

The point of the reply and this thread, so it's not hijacked, is paddz 700. I still contend I'd take it in immediately, whatever stage of running it's in, it shouldn't be stalling out, backfiring, etc.

 

You are right on PADZZ. We have done alot of testing on the Dyno's and the only way to break an engine in is WOT (after the camshaft is broken in)
A new camshaft should be broke in at 2000-2500 RPM for 10-15 min. Once the cam is broken it takes 3-4 dyno runs at WOT to seat the rings in a precision honed (with torque plate) cylinder and 10-20 runs with a cylinder honed without a torque plate.
The old saying "break it in the way you plan to drive" is VERY true.
Unless you only plan to idle your bike around, don't break it in that way.

 

Hey Lightman, I am one of those "engineers" as well as a race and highperformance aircraft engine designer/builder. We have done a lot of testing with breakin proceedures and after hundreds of hours spent on this testing we have found that engines broke in with the (baby method) never reach the same HP or last as long as ones broken in properly.
As with us not worrying about the life of our stockcar engines, well durability is our #1 priority power is our second. A 500 mile race puts more stress and cycles on an engine then several million miles of road driving.
I have worked with alot of engineers on aerospace projects, and ALL of the high performance production aircraft engines that we manufactured were broke in at max cont. power for 4 hours.
my 2 cents

 

Enjoy your bikes folks....and break them in as you like....as I said...it's your wallet...

 

It hasn't stalled since the 1st time out. I've yet to change the oil. It backfires every third deceleration (is that a word?). The coolant lid must not have been tight; hasn't leaked since. I've given it a few full throttle runs. I plan on putting around 2-300 miles on it next week during the hunt at 9,000+ elevation.

I can't believe how this thing wheelies[img]i/expressions/face-icon-small-happy.gif[/img].

 

My 2 cent's on break in......I have broken in a P650 and my new 700 the same way.......first and foremost a engine, rings, etc MUST have load on them to seat and wear in, the half throttle thing is HALF truth, meaning you should not take a brand new engine fire it up and go wide open for 5 miles, what I did was vary the throttle from barely above idle to SHORT burst's of WOT, never keeping it wide open for more than 10-15 second before I let off, I never cruised at a constant speed either, vary the rpm's for the first tank of gas, go wide open for short distances then let off, do this for the first tank, change oil and filter, and then hammer down, your broke in then, I have had great result's ding this with two different prairie's......

 

Thanks STAKK. That's exactlly what I've been doing. I've only got 70 miles on it now. When do you think I should change the oil? Should I do the filter as well? Oil looks very clean still.

3TV...I'd really like one of those too. You'll need to get yourself a storage shed. Oh, 3TV, do you ever store your quads in your toy hauler? I've been thinking of doing that.

 

with a CVT equiped quad the RPM varies anyway, & won't let you beat it if you wanted to... baby it for an hour, while you get used to the quad, then drive it like you intend to...WAM
