Followed a procedure similar to this one breaking in my 2016 Africa Twin. At 20k miles now it burn no oil and runs like a striped ass ape. Oil life seems to be good too still has decent viscosity and minor contamination between intervals. Clear and slightly dark like "tea color" but never black or cloudy. Great video.

I completely agree with your recommendations. From small engines to class 8 diesel truck engines I built as a professional tech, my first step was to heat cycle it twice. Verify no leaks while heat cycling. Then take it out and drive it like you stole it. Especially in a semi or a pick up truck in my opinion. Those engines should be happy at wot from day one.

No mechanical issues that need to be addressed immediately. All mechanical issues should be addressed immediately. Nice video, also lots of engine braking will help seat the rings. Also they say to run them hard, and to run it how you’ll run it so it’ll break in according to those conditions it will be in most of its useful life.

I have a 95mm bore. Converted to inches is 3.74 inches. My application requires the high performance street strip guide from the ring gap chart(.0045") for the top ring and(.0050") for the second ring. When I multiply those numbers by my bore size I come up with 0.01683 for the top ring and 0.187 for the second ring. What do you recommend I set the ring gap to according to those numbers?
@darrenbashby2 жыл бұрын
I do not think the ring gap should change by bore size. The rings should be gapped to manufacturer spec. If you are using factory rings stick to their spec regardless of bore. Same would go for aftermarket rings. If the recommended gap is 0045, that is what you need.
