Hey guys, new here but not to riding or my R6. I bought my bike in 2009 with 9k street miles. I stripped it down, sold the fairings and lights, and transformed it into a track bike. I'm now just over 15k miles (6k track) and was thinking I may be due for an engine rebuild come winter time. I change the oil every other track day with Amsoil full synthetic, changed the plugs and did a valve adj at 12k too along with coolant changes every year. The bike still runs very strong and burns no oil, but I wanted to hear some input from other members on how many miles they went before rebuild or it went "boom"
