Default Re: Break in procedure

What are you're oppinions on using synthetic to break in a 2-stroke?
How about synthetic for breaking in a 4-stroke?

I have my own opinions, and theories, but I would like to hear some of yours first.

my theory, not done at the expense of any machinery mind you.. is that i would break in a 4 stroke with normal petroleum based oil, and after break in , switch to synthetic. my reason is that there has to be a certain amount of wear for the rings to properly seat themselves in their grooves and have the faces of the rings mate with the cylinder bore.. the synthetic are don't break down fast enough to allow this to happen, and they also 'cling' better to the metal parts reducing wear on startup and overall..


my 2 cents.... man, i will never get more than that...

I usually let my bike idle for 15 minutes, let it cool for 20 minutes, and then run it as fast as possible. Ive done this with the 450, 250, and 125 with no problems at all.

Cool thing about the KTM's, there run in at the factory and then
filled with synthetic oil. I'm guessing they use reg ND oil to run it in.

I can't see how this would hurt anybike, 2 or 4 stroke, as long as it is completely warmed up first. Cold Siezing is a problem if you don't warm up first though.

I have bought quite a few brand new four strokes and I have babied some, and ridden the heck out of others and I honestly have never been able to tell a difference.
