Hi everyone my name is Craig and I'm new to this, I recently bought a dt125r 1999 model and It runs fine untill 5th gear where it stays at 9000 revs at 60mph (6th gear useless because of this) I de-restricted airbox which helped acceleration and I pulled out Reed switch (not cut just moved out of way) which I thought let it rev freely but did nothing? I know my powervalve needs put on right position as its lined up in restricted form and maybe my cdi needs de restricted? I've got standard exhaust chamber de restricted and a dep end can but I know it can do more than 60mph any ideas or help would

Be much appreciated thanks
