Since you glued the vehicle down sensor you'll need to check it's output voltage to make sure its at it proper voltage 3.7~4.4 DCV...Here's a bypass just in case KMS Tip Over Switch Eliminator Kit Kawasaki KFX450R KFX 450R For Fuel Pump / ECU | eBay

Try these setting 4,4,3 to get you running & fine tune from there

Now that you’ve removed the lexx it’s defaulted to factory setting.

they come preset for exhaust and air box lid removed.

plug it in and go.

Water temp sensor going bad?
or
Low fuel pressure?...!! If it runs crappy @ 1/2 to full throttle is the usual sign

I suspect a dirty/clogged fuel strainer in the fuel pump...!!
