CRF 450 Valve Adjustment

CRF 450 Valve Clearance Adjustment procedure. I had to re do the video to make it less than ten minutes. As a result the timing marks segment will be added as a response video to this video.

hey brian thanks for the vid it was very helpful i wish u were in orlando fl, got one question i adjusted my valves, on the cam carrier i put it on and the lobes are not out my timing makes on the crank are lined up do i take the carrier off and turn the lobes outward. i had to to move the timing gear to get the bolts off with the chain slack.

@MrKMENACE82 Could be. You just have to do whatever it takes to get the marks to line up. The cam CAN be off a half turn because the crank rotates twice for every one time the cam turns.

is it possible to change piston when the engine is still attached to the bike, like this in video?

[briansmobile1]

@tjalolx Yes

good video dude ! did you have any problem taking the camshaft sprocket off? mine kept wanting to turn the motor, even when it was in gear. any tips?

[briansmobile1]

@FlatBlackBurb You can put a FAT screw driver etc through the opening in the cam wheel and bind it on something to block it's movement.
