Different combustion chamber design between the 550 and 650. Best for the conversion is the chain drive (81-82 GS650e), it has more aggressive cams. Shaft drive 650 head and cylinder block can work, but you can't use the cam sprockets from a shaft drive engine (different tooth count). 81-82 550 engine should take the cylinder block just fine; earlier 550 engine cases will require boring out to clear the cylinder liners.

I'm trying to wrap my head around not being able to find a 16 inch tire. 130/90-16 is one of the most common bike tires out there. If you're only dealing one local shop who only deals with one supplier, they could be out of stock for the moment. I just searched on Flea Bay and they have lots of them, and I'm confident Amazon will too. If you really prefer a 17 inch, then go to the time and expense to switch over. If you just want to ride, look for other sources of tires.

In the US we had for two years (81-82) a GS650E. Chain drive, performance heads, 673cc. The engine will drop straight into a GS550 frame. There is also a conversion mentioned above. It's been discussed on this forum in the past.

Anything good at the swap meet? There's a big annual winter swap meet in Pennsylvania (York, I believe). I've never been there, but I hear that it's good.

Jeroen, I have same bike and color (US model called GS750E). US dealers no longer sell the stickers; EU dealers likely don't either. Try Tony's suggestion. An automotive paint supplier should be able to match the color, or a close enough shade of black should be available off the shelf.

One of the great things about old Suzuki motorcycles is that many of the bearings and seals are standardized metric sizes. Try to find a four digit number on the seal. Match that number up on a bearing supplier's website. I've had good experience with: Bearings Direct Your High Quality Online Wholesale Bearing Store. I see you're in Maryland; I'm in Virginia so only a few hours away. Notice what I said in response to your other post. Introduce yourself (your interest in Suzuki motorcycles and what brought you to this forum).

Also... in my experience, the E models normally had the screw-in fork cap shown in the manual; the L models had the c-clip.

Yes, like Tony said. You'll need a fine sharp pick to get the c-clip out. Growing a third hand may help too. The c-clip is made from thin spring wire, often get rusty, good to have replacements on hand.

You may not be getting an answer because you sound like a "one-post wonder". In the past we've had people come on here and ask a question. Members would take the time to answer it, and then we never hear from them again. Take a few minutes and give us some brief info about your interest in Suzuki motorcycles. Doesn't matter if you've been wrenching and riding for fifty years, or if this is your first bike.

Can you simply replace it with one having the normal lever?

Could the injector be fitted to the intake boot?

I briefly had a GZ250, it had belonged to a friend of a friend. It had been a starter bike for his kids to learn on, then it sat outside for years, free for the taking. The GZ250 was a small cruiser with the same engine. I got it running and made a few custom modifications, then sold it to someone who wanted a starter bike for his family members. Not hard to make some money off small bikes: get them for free or cheap, spend a little money and time to get it running/rideable, and sell. Your bike looks like a good candidate for that. Might market better with different paint.

They were a good bike but only in North America for two years (81-82). Size and weight of a 550 with neary the power of a 750. Good flowing head, 673cc.
