Can you attach pictures of the plugs if you can please ?
Side view ( so we see threads )
Top view ( to see middle colours )

Also have you tried a fresh set of CR8E plugs ?

Also , are you able to test your coils for primary and secondary resistance ?   (sometimes coil is bad, and HT caps can’t output enough spark power to plugs at high revs)

Also , remove HT caps and measure ohms of HT caps without coils attached to it.   (sometimes coil is okay but HT cap is breaking down / stress)

For the Jet needle , have a look at this tutorial to see if it helps
