you have just had your first experience of a seizure... Sad

Check the oil lines and tank make sure it has 2T in it...

HAve u recently added a exhaust or different air filter ? or carburettor ??

The barrel, and or piston could have suffered damage from this too

it should be more likely a lean mixture or a badly adjusted oil pump . to correct the mixture upjet your carb , clean and oil your air filter . using the pilot screw has no effect at high revs .
take off your plug and compare the colour with this link https://www.dansmc.com/Spark_Plugs/Spark_Plugs_catalog.html
then have a good look at your oil pump
prior restarting ,by the plug hole ,drop a coffee spoon of oil , pass the 2nd gear and move the bike several wheel turn . then put a new plug and go gently for a while

Nipped a ring mate, by the soundsof it you don't know how to fix it, so I'd take it to a garage chap Smile
