Viewer Questions:
Q: If break- in happens so quickly, why do you recommend using petroleum break- in oil for 1500 miles ??
A: Because while about 80% of the ring sealing takes place in the first hour of running the engine,
the last 20% of the process takes a longer time. Street riding isn't a controlled environment, so most of the mileage may
not be in "ring loading mode". Synthetic oil is so slippery that it actually "arrests" the break in process before the rings can seal completely. I've had a few customers who switched to synthetic oil too soon, and the rings never sealed properly no matter how hard they rode. Taking a new engine apart to re - ring it is the last thing anyone wants to do, so I recommend a lot
of mileage before switching to synthetic. It's really a "better safe than sorry" situation.
Q: My bike comes with synthetic oil from the factory, what should I do ??
A: I recommend changing the factory installed synthetic oil back to petroleum for the break-in period.
