I'm going to be installing a new Timing Chain on my 02 FE501 once I get the new one from Boss. Has anyone detailed the install within this forum. Like where the sprockets need to be lined up etc.

Piston at tdc and turn the cam so the lobes are pointing up, use some kind of straight edge position on the lobes, then the straightedge should be paralell to the gasket surface of the cylinderhead, then you know you are right.

Thanks for the response. Sounds simple enough, I'll give it a go and see how it turns out! Does the time sprocket need to be in any certain position?
Hi,
There are dots that shall intermesh on the gear of the crankshaft and the gear of the chaindrive/countebalancer. At TCD, that is.
If you search the forum, somewhere you will find a nice drawing of this. But really, its simple, just look at them dots when you have the clutch cover off anyway., before you take the old chain off. Be aware that yout TDC marks might be a little out,
Here's an extract of a post i did not so long ago:
------------
Installed the new cam chain & new style tensioner, removed the Alu head and cut 1/3 off the spring. The chain is now tight and didn't even move a click when putting the spring in.
Got the timing right, and also checked TDC using "dead stop method" Mine was 8 deg out. Using the new TDC there was NO doubt in how to time the gears and make the cam lobes equal height when installing the chain, whereas before tho whole thing seemed to be 1/2 a tooth out. I left the ignition timing as is, and havn't strobed it. So knowing the real TDC doesn't really make a difference to me, other than timing the cam & gears was easier when spot on, as per book !

Hope this helps, if not there is shitloads of info on this topic on here anyway.

A picture says a thousand words 
lower gears like this
Cam like this
Put a metal ruler over the top of both cam lobes, then measure to the side of the cilinder head, that way you can get it perfect.

hello, i changed mine a few weeks ago and i was so bored to remove exhaust and clutch cover, that i just removed the rocker cover , removed the tensioner,split the old chain, connect the new chain to the old one, turned slowly the engine until the old is completely out , removed it, put the engine at tdc, put the camshaft etc.
