Aright, so I'm doing a Full rebuild on my 2010 kx250f. Top, bottom, valves, the whole works. I have 100 hours on the bike with the stock bottom end. I have replaced the piston twice in that time. I would like to get some input on what's good and what I should stay away from. I am also looking for some extra kick like cams and high compression piston. Any other little mods worth doing instead of that? All input is appreciated!! I'm going with the Hot Rods bottom end kit but not really sure what I should be going with in the top end... - Better valves to be going with? OEM titanium, Wiseco, Kibblewhite, steel? - Vertex VS Wiseco - High Compression VS standard - Thoughts on Hot Cams? stage 1, stage 2? What are all you guys running in your 09, 10, 12, and 13, kxf's?? Thanks!!
