Hi all, I am currently riding an 07 YZ450, and do all of it in the woods. I have made the usual mods like skidplate, handguards, radiator guards, side stand and spark arrestor. As well as O-ring chain and changed gearing to 13-52. My problem is I have the 2T bug again and am not sure if I should keep my YZ or go the 2T route. If I keep it, what else should I do to make it a more capable trail machine? I was thinking about a heavier flywheel or maybe a Rekluse clutch, but rather not have to spend a lot more cash if possible. The suspension is already set up as well, so I won't need that done. My current complaint is that in really tight areas the motor sounds like the valves clatter at slow speeds, and I am afraid it may damage the top end. The 2T I am considering is a 2008 KTM 300 XC-W. My friend has an '04 and I really like riding it once in a while. The 2008 is set up with all the same stuff as I have now except the suspension needs the correct springs for me. What should I do?
