Hey guys, I'm fairly new here and I'm building up a Medina klx clone with a yx 150 engine. I should have everything here in a week or 2 and will post up some pics of the build. But before I order the klx clone how much of an advantage would the linkage roller be? Has anyone compared the 2? And what can I do to get some more power out of the yx 150 without any major expensive mods? Just wanting any opinions or ideas for the build. I'll be sure to keep everyone updated with some pics when it all gets here.
