If oil is leaking at the top of the motor on a Yamaha 250 Bear tracker this could be caused by a head gasket or valve seal. To locate the exact source of the leak try removing the bolt near the top of the motor and use degreaser to clean the area. Once the area is clean run the Bear tracker to locate the leak.

the mark on the camshaft timing gear needs to line up with the mark on the crankshaft timing gear to ensure the camshaft is in proper time with the crankshaft. Keep in mind that the marks will only line-up every other revolution of the engine due to the crankshaft spinning twice as fast as the camshaft.
Connect timing light. remove vacuum line and plug to put engine in base timing. loosen the Distributor hold down, turn the dist. left or right to set it with the timing light. tighten the hold down. replace line. White out makes it easier to see the timing marks. the stock timing is 10 degrees
No it has a timing chain
