And use grandmas oxygen hose to listen for motor noise. Use the wife's car to jump your raptor. And keep the language clean so my daughter won't be offended, lol. Oh yeah, don't forget church music... Judas Priest, Godsmack, Stone Temple Pilot, Black Sabbath, Lamb Of God, and more that slip my mind.

So I understand this post you are saying I should:
1. Warm the engine up (how long for 2006 Raptor 350)
2. After warm up ride it hard
a. Run through 2nd 3rd and 4th with some power
b. Let off the gas in different gears and let the engine slow the bike down
c. Repeat #2 for at least an hour.
3. Change oil after break in ride.

Is that correct?
After honing, wash the cylinder with Dawn soap and water and a good brush till a white paper towel wipes clean. Dry with a heat gun or hair drier. Wipe the cylinder with oil used for the motor. WD40 may not be compatible with all oils. Lube the rod at the crank, wrist pin, rings and piston with the same oil. Some builders think a dry cylinder and rings will seat faster, but I don't like that idea. Start the new motor and check for leaks and shut down ASAP. Let cool down and re-torque the head bolts and check other mounts, cases, etc. Next time it's fired up, be ready to ride aggressively, but don't lug it. Follow the link on the first post of this thread, I've done it for years with 2 and 4 stroke motors. AKA, ride it like you stole it. I always recommend a magnetic drain plug.

Ride it like you stole it...........What if when you steal a bike,, you like to gingerly ride it through the country side and take in the scenery? Lol

I just stumbled on to your website and I must say alot of the thing you say in the posts about porting make so much sense that its scary. I've been building race cars and two stroke bikes for years and have never heard of this concept.I have just recently put the head of my 660 raptor in the shop to get the ports over sized,then I read this and now I wanna run down there and rescue my head but I will let him finish his job then I will go behind him and try your way. I've tried so many ways of getting more power out my builds without making them delicate but,the way hte I was taught was to go bigger. In doing so that made the engine thinner and more delicate. Your way adds strenght and keeps the overal integrity of the meatl in take, therefore kepping it strong and that way it will last longer. Man I wish I had known this info sooner,I'm taking this concept to the local track. pbir here i come!

tevennealy32 I have been working on bikes for more than 10 years now and he is absolutly correct and to answer your question (foot) the same gos for street as in dirt or (track as he said it in the post) The only real difference is when your dyno breaking it in. I've almost specialized i two stroke bike and quads.This has been my break in process for years and none of my projects have breaken during this process and all of my customers are running hard and strong. An old engine builder taught me that a long time ago,I was building drag race cars.He asked to to look and see if the top feul drag guys were breaking in there motors before there next run. Hellllllll no, they put that sucker together in a matter of 1 1\2 hours, push it ot the line and run the wheels off that puppy. After that, I always broke it in by running it like i stole it. With some caution of course.
