YFZ450 ( How to set Cam Timing - Which Mark is TDC - Sideway H or I )

[@Trap..house.]

Thank you for this video!

No problem, Glad to have helped.

ANYONE WORKING ON YOUR BIKE RN! MAKE SURE TO TIME IT ON THE UPSTROKE OF THE PISTON!!! PUT A SCREW DRIVER IN THE SPARK PLUG SLOT AND TIME IT ON THE UPSTROKE. IF YOU TIMED IT AND IT WILL NOT START YOU MAY HAVE TIMED IT ON A DOWN STROKE LIKE MYSELF! TOOK APART MY BIKE 5 TIMES YESTERDAY AND MY FINGERS HAVE BICEPS 💪 NOW

[@trxtech3010]

haha. Yes sir. i've had my fair share of taking things back apart.

[@TheMadMonkey3]

I mean, as long as you line up the dots on the head and the little mark on the flywheel you should be good right?

[@JasonH-p8f]

No don't use a screw driver. Steel on aluminum. Use a wooden pencil. Softer then your piston non abrasive

[@johnbrass8910]

Depends on what year, the 2013 is cam timed at 23 degrees ATDC to the cam dots, aligned with the case

[@trxtech3010]

it doesn't matter as long as your timing off of the marks that's all that matters...

[@Bob.482]

How do you check if you have the backwards head style?

[@trxtech3010]

it's just the more newer head the exhaust comes out where the carburetor would go. They are also four valve heads.

[@ianbatura340]

When i line up everything it looks great but when i go to tension the chain the the two dots on top are not lined up on the flywheel anymore. Would you know why?

[@trxtech3010]

The timing chain is worn out.

@@trxtech3010I know this is a old video but I just put a new timing chain on mine and it looks good but when I put the tensioner in one of the cams spins over and then it’s out of time

[@hunterellis6614]
