Yes, it's a controversial topic, but do KNOW for sure?

actually, i believe it. i dont know for sure tho. some say ride it like you stole it... others say take it easy for the first 24 hours or whatever. who knows. as long as it runs after the break in youll be fine.

 

I have always ran my 4-stroke motors just like he stated, just making sure to let it warm up first. I always changed my oil in the car motors after the first 100 miles also. My motors always ran good, didnt smoke, and lasted a long time. It makes sense to me, and goes along with the old saying break it in like you want to drive it.

 

That's very important! Even after break-in. Let them warm up. Otherwise it can cold sieze.

You know when an engine builder puts an engine together. He takes it and puts it on a dyno and opens that baby up!!! He doesn't call up Grandma and tell her to come down and break-in his engine...
Break it in hard and it will run hard..... Break it in easy and it will use oil.......

 

The warm up is important

 

Actually, his method seems right to me.

 

he's right and wrong on these new nicasil(dont know if thats spelled correctly)cylinders you will never break them in there so hard even after running a full season on them ive seen absolutly no wear or even breakin markings.
if your running steel sleave than i would say run a tank of gas thru it first. however i dont think you could hurt them very much either your just giving the rings a little time to knock the scuffs out of the cylinders.

allways warm it up thats when you do the most damage

 

I'm sold breaking motors in easy stinks so if riding them hard the first time around is good than thats what i plain to do
