You'll get a hundred different suggestions as far as cam break in(me included ,but just use common sense! Just drive it around for a couple hours at varying speeds,but no sustained wide open throttle! The same as you would a new atv as you really are breaking in new parts!. You can run it at first for a little while as you said and longer the second time IF you wish! The MOST IMPORTANT thing is to drain the oil and filter,have the sump drained and clean the oil tank fitting screen for any metal from the previous cam that could get back into the engine. OPT

mad-atver.......It seems by the tone of your thread that you really want to do things right for the break-in of your new cam. I lean towards OPT and TLC's thinking on the proper weight of oil. Knowing what I know, I believe there should be a 0w40 synthetic oil in your motor on the first startup or the Polaris synthetic.
You can try and might be able to return the 10w40 oil for the recommended weight......if not opened. Good luck.........NoJoke
