4:10 - I was curious and looked in the service manual and it does state on section 7-18 to "Tighten the cylinder head mounting bolt" just after the step of installing the camshaft holder and tightening down the camshaft nuts to 14lb. Sorry to resurrect an old thread but going thru this now and your video has been a great help so far!
If you're doing this, the way you get the bolt holes to be accessible is by rotating the cam and sprocket. If the holes align and you follow my advice, you'll know it's correct because the sprocket only fits on in 1 way. It doesn't matter if you're off TDC when you put the sprocket on the cam, what matters is that they're off TDC by the same amount. Get everything correct, then remove the sprocket and rotate the cam so a bolt hole is accessible. Then turn the flywheel to turn the sprocket until the bolt holes align (in same direction of course) The single most important thing is keeping the chain under tension as you turn the flywheel. If it's slack, it could jump teeth and now the bottom end is no longer in the same orientation in relation to the cam shaft.
Thanks for taking the time to make the video! Doing a rebuild and cylinder for my cousin and couldn't find the owners manual anywhere now I'm almost finished the build lol
Very helpful videos....thanks. I did notice that on your upper timing chain sprocket, that you have those two sprocket bolts backwards......the shiny one should be on the left and the black one (dowell bolt)goes on the right.....with the TDC mark at 12:00.
@@TN_HondaDad Good question.....I could have answered it 5 yrs ago, but now I have forgotten. Perhaps to ensure the timing is done right? DOH! Getting too old, my memory is failing me.
How did you get the cam sprocket on so easy? I can't get mine on!! I have the gear with the timing chain on it and am trying to pull it up to get the center hole on cam shaft and can't for the life of me
If i remember correctly, i unbolted the sprocket from the camshaft slid it up under the chain, raised the gear up and bolted it back on. All the while i had the cam chain tensioner completely removed......that is critical.

crazeyspivey glad you like the videos. Thanks.
I have often wondered that, why is that?

extremely helpful
You definitely want to add motor oil to the bath under the cam. More important than that grease.

+courtland godwin have you removed the tensioner?
I can't get mine on either
my honda spacy bik a 100cc engine a gasoline jacuzzi . What is the feler mumber for the gasoline jacog and the number for the exhaust jacog in mm
How did you get the timing chain tensioner back to where it was
Sorry, I do not remember. This was years ago
What do I need to do if the cam binds and doesn't turn at the same rate as the crank?
Great video! This is the same process for a 1999 XR100R right? Thanks again!
Yes, same process. You might want to verify if the valve clearance numbers are the same.
How do you get the sprocket on the cam, my chain is so tight I cant get it on.
If i remember correctly, i unbolted the sprocket from the camshaft slid it up under the chain, raised the gear up and bolted it back on. All the while i had the cam chain tensioner completely removed......that is critical.
i can not get on cam on there it will not fit up
Please help
any bodies help would be grate
Hmmm you sound like an A&P
