Hi all, running a 2014 390 as a race/track bike only and having head gasket problems, just had the head machined due to normal warp issues with early models. Just been to a track day and the head went again in the last session, no noticeable overheating issues after doing cooling mods, ( better coolant, 1.6rad cap, motor heat shroud removed, radiator cowling fins removed, etc) missing the start of the racing series , not happy. Running Akar exhaust, Athena GET mapping, K & N and a few air box mods.
Any ideas, noticed only two cooling ways in the barrel with one restricted by the head gasket, has any one made this small hole in the gasket bigger?
Thanks in advance.
