what are you like!!!
when you got the mark of the crank in the little round window you should be able to see the following on your cams;
the exhaust cam
the nine o'clock dot should sit clear of the cylinder head in line with one camchain pin. the camchain pin south of this will be absolutely in line with the head.
the three o'clock dot will be out of sight below the top of the head.
the inlet cam
the nine o'clock dot will be a clear tooth of it's wheel clear. the bottom edge on the south side ( the bottom "valley") of that tooth should line up with the head.
the three o'clock dot will be absolutely in line with the head.
remember that when you put the chain tensioner back in & tighten it all up, the cams (especially the exhaust) will roll about 1/16" clockwise.
try to use a zip fastener to lock the exhaust camwheel to the chain.
do the exhaust cam first.
copy this off & take it into the shed with you.
you should end up with the exhaust camwheel heavily tilted clockwise & the inlet only slightly so.
