Hey Chris,
Yep, when you have time check if the round mains fit on your KX.
Unfortunately the pilot needs to be sorted out also. and with the temps cooling off soon it will need to be larger.
You are gonna have to find something to put between the frame and the brake lever to get that thing to come off.
What may have happened (besides rust) is a groove has worn in the part of the brake lever that fits through the frame, and the brake lever itself. (or at least the pin that rests in the frame)
You may have to also remove the footpeg to get more up and down movement out of the brake as you pry it off.
Of course when you have time.
I think the chrome shop will want to see the item before they give you an estimate.
What are you guys gonna do with the bulldog after it's done?
I imagine that puppy is gonna be heavy when finnished.. ( yes..pun intended)
Catch you when you have time. try to get some sleep. My daughter couldn't sleep nite before first day.
