Hi I have a 2007 yz450f and would like to know what are some good upgrades to improve the overall handling of my bike.
Parts:
Factory fx gripper seat
All new graphics
Gytr head
High comp. Piston
Hot rods crank
Boyeseen complete water pump
Hinson complete clutch
Heavy duty clutch springs
Bridgestone battlecross x40 tires
Geared 13/49 for track riding
48 pilot jet for carb
UNI air filter
aluminum throttle tube
And new fork seals and bushings

Besides all of that I've only clicked my suspension and set my sag every race.

I was thinking maybee a pipe?
New triple clamps?
Doesn't feel that corner friendly. Power is not a problem at all as I can hit a 75 foot triple 2nd gear no problem.
I keep up to date on all of services change oil every other ride along with all filters.
And valve adjustment every 20 hours. Thank you in advance.

Dunno why you'd have to set your sag every race unless you carry a dumbell sometimes and other times not...
 

But you obviously need to get your suspension set up. Any good tuner can take care of you or do the homework and do it yourself, lots and lots of SSS info on here. You don't have many mods on that bike but in reality, an MX bike being used for MX doesn't need much. Get the suspenders dialed and ride.
