2009 ktm 300 xc rebuild
Hey, just wondering when i should do a top end on my bike i bought used with 61 hours on the whole engine. The bike has a S3 high compression head and still stats first kick and has a ton of compression. I mostly do slow technical trail riding as its my second season in either first or second gear for the tight stuff but i love to hit the pipe on the more open stuff. You could say i ride like a grandpa in the rpm right below the powerband for most technical riding (like low to moderate rpms in lower gears). Just wondering when or if i should plan on replacing the piston. First 2 stroke i have ever owned. Any advice would be great. Jetted slightly rich, running 50:1 amsoil dominator. Ive seen some people say cast vertex pistons will last longer with tighter clearances but im running a high compression head so is forged better??
