I'm a newbie to forum but intermediate rider both mx and trails. My bike is super smooth on the throttle, at this point its too smooth. I'm looking to get more pop out of the bike. I rode my buddies 06 KX450 and all the front wheel wanted to do was come off the ground! I loved it! I'm 6'4" 210 and can handle the power. Maybe my bike is exhausted? So I'm on a budget, and won't be able to go crazy on the bike right away, but over next couple months I wouldn't mind sinking some money into it, if it will increase performance. Getting ready to get new clutch setup since mine is trashed (5 yrs on OEM clutch not bad). Jetting seems perfect and valves are in tolerance. No aftermarket performance parts on the bike. My question is: what is list, in order of most significant benefit, you all would consider for upgrading?
