The spark plug size shouldn't change. Most use BR8HS or BR7HS. 90 is a good size main, but if that's what works best on the 50 it's pretty likely you'll need to go a little larger.

for the zumas we run either an br8hs or br9hs now if you are running a polini or other long reach head you will need es plugs the liquid cooled kits also run es plugs
