No ideas at all, silly or otherwise other than persevering 😕😕😕

Y'know, it must be nearly 3 million years ago when I had the head and barrels off my 400, but I seem to remember that on re-assembly, you fitted the chain to the sprocket, observing the timing marks on it, then fed the camshaft through the centre hole and bolted it into its correct location. I certainly remember doing this on my 750 which if I remember had "ears" in it so that the camshaft would pass through the centre hole. Hope I haven't lost the plot completely and dreamt all this up!

SeanFD:
Haynes says to feed the shaft through both chain and sprocket, line things up and then put the chain on and finally put the guide/tensioner in. I got all teh way to the very last step; now the guide slipper won’t slip.

Maybe your way would have been better as then I could have left in the guide and tensioner. Out to try again shortly.

They say it’s short-term memory goes first  ;) You are correct; the 750 sprocket does have “ears”

Bryanj:
Its a long time since i did a 400 but the 500 front guide goes inside the chain loop not ouside and if you fit it wrong the chain dont fit

SeanFD:
On the 400 it goes outside Bryan... I hope!
