GS450 carb confusal...

I'm a bit confused when I look at different threads here on carbs for the 450. I have an '81 GS450S and according to the spreadsheet I found in one of the carb threads all of the 450's had BS34SS carbs on them. When I looked at the bikebandit website to check part numbers across the years (for interchangabilty on carb parts) I see the slide part numbers are different for 1980-81 than for the later years. Will new slides/diaphragms work in the older bodies? Mine have some holes and I was thinking about going with the diaphragms from jbmindustries. It seems easier and more sure fire than the plasti-dip repair method. I just don't want to end up with diaphragms that don't fit my carbs. If the diaphragm only part numbers were listed on bike bandit I wouldn't be asking this question, but I know the slide & diaphragm are sold as an assembly...

It seems like a guy could make some extra money 'rebuilding' slides.
 
The 80 - 82 450's carb's are BS34SS and are all the same. They changed in 83 but not sure what model they are.

The slides and diaphragms, jets, etc. are all different so I would suggest later ones won't fit.

Looking at the jbmindustries.com page, just measure for the right part as it looks like there are two options for BS34 carbs. Looks like just go here:

Do us all a favour if you order them and tell JBM what you're putting them on so they can add the model of bike to their list :)

Thanks, I've been looking over some of the information you gave me. I know I'm in the right place for collective wisdom on GS models. I've found owner forums and newsgroups to be extremely helpful in the past. I only hope I can add something with my presence.
