Good progress Mark.
Do you know if the engine has been apart before as there should be traces of the old cement on the cases? Yes, use Hondabond, very sparingly, just a thin smear, you don't want it oozing into places where it shouldn't once the cases are bolted up.
Renew the drive side seal but be careful, use plenty of lube on the lip that fits over the output shaft and make sure the shaft itself is clean with no rust because you need to push the seal over the output shaft from the end and any debris could rip the lip of the seal (dont ask me how I know
).
There are also two seals in the rocker cover (rev counter drive and valve lifter) that will need replacing and asumming you have taken these items out for inspection or cleaning and also the kickstart and gear lever seals in the outer covers.
I had my chain joined by Andy Chain who visits Kempton Park selling...chains.
The Haynes manual explains in some detail about the balance shafts, you need three hands though as the chain passes over one of the balance shafts in the crankcase and you have to hook it over before you join the cases without it slipping from the mark (and trying to avoid touching the Hondabond!). You will need to put three marks on the new chain and these line up with the marks on the balance shafts.
