I just dropped the pan and the cheap gasket was torn in the corner where it was leaking. Lesson learned.

You're welcome. There is one part that I have not been able to find to be interchangeable, the seat. I even tried ordering a GT750 seat pan from the UK. It's not a direct fit and I could probably make it work. Luckily, I found a seat on ebay that wasn't too expensive. The cover and foam were completely trashed but It's the pan that's important so I jumped on it before anyone else could. I plan on making a solo seat out of it and using the spare space for a tail rack so I can carry my lunch to work. Later on I will put a Cafe-ish type tail cowling on it.

My point is if you can get a spare seat or just seat pan for less than $100 jump on it even if you don't see a use for it right away.

Never thought of a Corbin. Don't like the red/black plus it is not in very good shape. Looking for a stock seat cover.

This is as close as you are going to get. You are going to have to modify the foam under the one you have.

Thanks for the tip. Just ordered one. I have done Seat Concepts covers on my dual sport and dirt bikes so have some experience with seat covers.

Is your seatpan plastic or fiberglass?

OK, just wondering. I know Corbin used fiberglass a lot. The factory ones are plastic.

Looking again it looks like a modded stock seat that's been cut down and recovered.Going to do one of those Pit Replica covers on mine when I get that far.From everything I've heard they're really good!You're most likely have to add back the foam like GPzMOO750 said.

I've been thinking, if anyone needs an original seat pan I'd be willing to work a trade for an aftermarket pan. I'd feel less guilty doing any significant mods if needed.

Is this correct sequence of parts? I forgot how this went back together. I looked at parts fiche and it showed it this way but that was not the way I had it set up.
