Unknown year model

Until recently, I think the old GL's escaped getting seriously hacked in their youth and most survived fairly intact. Other UJMs and twins were not so lucky over the years. But, now that we lovers of buxom nakedness are having our way with the GL's, there's more funny stuff going on. Back "in the day" it was more about bling on the old Goldwings. Now, as Robin notes, could be anything.

The only reason it matters is because of part fitment. Will any part from a 75-77 interchange?

[Whiskerfish]

All the substantial parts from 75-77 are the same with the biggest exception being the carbs. Many had minor changes but should bolt up and work just fine.

Carbs are individually different in several ways, but essentially the same. Don't mix years within the same rack. Some 75 cams had a shorter stub on the fuel pump end of the left cam. Some 75 frames didn't have a bracing under the shelter that the rest do. Could be some other internal differences in various components, but almost everything from one will swap over. Most 77's had a thicker casing in the block to help quiet primary chain noise.

That's all I have that comes to mind.

I"m going with 77. Thanks everyone. Yeah, tapered neck bearings!
