The guy I bought my 250x from said that it had a wiseco piston installed recently. I looked on the website and it seems that Wiseco only makes the 12:1 piston for the 250x, and it's very hard to kick over, almost like my 350x. So am i right in assuming I should be running 93 octane in it, I dont want to wreck anything.
