Hello all, Im fitting a new camchain gear to crank and wondering how it is timed... Im thinking line a tooth up with keyway and press on there... Is this correct??? Can someone confirm this... Does anyone have a workshop manual on these...

With the ignition cover off you should see some marks on the flywheel , the T mark should point straight up and align with the mark on the case , the cam sprocket should have a dot , it should face straight up as well , and the sprocket bolts should be level like this
O O , I believe that engine has 2 timing chain tensioners , one near the bottom of the cylinder , at the rear on the left side , and one near the top of the head on the same side (ignition cover side) , the bottom is the main one for setting the basic tension and should automatically set once you loosen the adjuster bolt , then once the bike is running , if you hear any ticking , you adjust the top one on the head to fine tune it if needed .....

To post a picture you need a hosting site like IMGUR or something , you use the links for Forums or Message Boards , then copy that link and paste it into you post it will look like this [img]https:/ /i.imgur.com/LOQoe1O.jpg[/img]

From memory with the little xr engines, with the lobes facing down the cog goes with O marking at the top.

lets see if this works... these are the pictures of camchain gear that needs to be pressed on crank

[JimDirt]

Yikes !!! , hopefully you have a replacement gear because that one is toast ....... but to answer your question , you align one of the teeth directly centered to the keyway

[bruzer]

Yep have one on its way... Thanks for confirmation Jimdirt.... Much appreciated...

And I am guessing a new tensioner as well to stop it happening again.
Have to be the worst sprocket I have seen.

[bruzer]

Yes new tensioner,valves,chain and sprockets...

Properly only need head nuts/rocker gear torque..
But if someone as list would be great.. cheers guys
