i dont understand your question. should have sight glass on engine or a dipstick . check level by removing dipstick if equipped . check w engine cold before starting every time you want to ride. should be inside full marks or you can damage engine. sight glass should be full of oil if you can see silver inside glass dont start or ride. damage will occur.

Take it to a PROFESSIONAL Factory trained mechanic..they have the skills and expertise to figure out why this is happening. Make sure YOU tell the mechanic everything you can think of..your riding style,..do you drag race it?.. do "burnouts"?.. play in the mud..??..etc..etc..
He needs to know this!! (he will ask if he is really good!!)

Check the fuel flow through the tank valve. There are screens inside the tank that may be blocked and restricting flow.
