It must be something about oil pressure. Or there is massive oil leek so you are on low oil level again or something with oil pump or filter.

4000 rpm ???????

try buying a new battery

My first guess would be the fuel pump. Alot of defective pumps will operate until they warm up.

DRAIN CARBS FROM PETCOCK AT BOTTOM OF EACH CARB MAKE SURE FUEL DRAINS COMPLETELY THEN TURN FUEL BACK ON, IF THIS IS AN INJECTED MODEL DRAIN TANK AND FLUSH THEN RUN IT HARD FOR 20 MILES OR SO, MAKE SURE YOUR OIL LEVEL IS OK

When starting any engine, run engine until it will idle without the choke on, then ride.

Sounds like electronic ignition

your cdi unit is suffering a from power surge try to check the output power if it is stable.

you have a damaged seal replace it and you should be just fine
