i cant be sure but the nose coming from your bike might be your piston rod hitting your engine, you may need a new crank shaft, they go on eBay for around 130

One of the ways of troubleshooting an electrical problem on a 2001 Yamaha 660 raptor is by starting the engine. The other way is by switching on the lights.?æ
Take it to a mechanic.
Sounds more like a lack of oil or oil circulation problem. I hope you are not one that races the engine to hear how good it sounds. Flush the engine, change the oil and filter and never race a cold engine to warm it up. The rattling may be worn out lifters. Now pray. lol
It could be a loose radiator grill, license plate holder or similar. It could be a loose cap in the engine compartment or even a problem with the engine.
No
Your engine is shot. Rings or valves, probably both, are shot.
The lack of oil may have caused a bearing to spin. The noise is most commonly called a knocking rod. Time to rebuild or replace the engine.
The oil light is not there to let you know the oil level is low. It's to notify you that the oil pressure is low. There are many things that can cause this, and being low on oil (you'd actually need to be almost completely out of oil) is only one of them. Take it to a mechanic to find out what the problem actually is. "Rattling from engine" is a bad sign.
The engine size is Yamaha WR500 in a 1993 waverunner, the engine size is right in the name of the jet ski.
Hmm, water in the oil filter does indicate a problem. Head gasket possibly.
The Yamaha PSR-9000 refers to a model of Yamaha keyboard from the PortaTone PSR series. It is not a type of vehicle and thus, does not contain an engine.
