Had an eyeball of the 90 chestplate and I don't think it will work. The bolt holes aren't in the same place.
Changed the reeds over, it already had carbon reeds, don't know what make they are. Compared them to the racing CCM reeds, which are much thicker.
Also cut out part of the bottom cowling which was in my way,
hopefully now I can get a set of stacks on.
I left the carbs soaking in the parts washer, probably have to strip them down to free off the throttle and choke.
Still to do:
change gear oil
get a tiller and make it work
just waiting for the pull start and cowling and I can fit them
fit old merc damper
