Break In

[Rob R]

I wonder if I ran hard enough to really seat the piston rings. I am sticking to the recomended not extended opp. over 5500 untill 1000 miles. Lycoming has good site about break in with aircraft engines.

Well, by the 3rd or 4th post this will be moved to the NEPT page. Don't worry about it. If you follow the guidelines that Yamaha published all will be fine. There are a number of differing philosophies concerning proper break-in. The peculiar conclusion is: None of them are wrong or especially damaging, as long as the vital fluids are kept to the proper level.

Uhm, just what would you have to do to aid in seating the rings on "coated" cylinder walls?

Ride your bike and enjoy it.

Rings, I like mine briefly dipped in beer batter, heat cycled at a temp of at least 365 degrees until golden brown. Once completed I like to break them in with a coating comprising of a thin, uniform layer of ranch dressing. Follow this break-in procedure and I can assure your rings will be perfect for years to come. :nyam:

Just doing my part to keep this out of the NEPRT.

I prefer mine saute'd in red wine with button mushrooms and served over my medium-well steak. :cheff:

Rob may have inadvertently started something here. Maybe the forum needs a recipe section

That sounds good to me. What time shall I come round? :dribble:

One thing to remember is that airplane and boat motors are a little different animal than your typical street motor. They are built with much looser tolerance. This is because they never get to relax when under way. They are always under load. If they are built with the same tolerance as a typical street motor they would over heat and seize. I learned the hard way. There break-needs and the way they need to perform are different. Follow the recommendation in your owner’s manual.
