I can't say for sure if the condition of these carbs is after 60.000km or less, I was told the bike went in for carb work but the extent of it may have only been to pop the float bowl off.
Cylinder head side of the carbs.

Loads of carbon and cylinder sludge has been splashing into the carbs due to the tight intake valves not sealing, this shot is the diaphragm carb.

Same cylinder side of the carbs but this shot is the throttle valve on the regular carb.

One of reasons to do your own repairs, I was told when I bought the bike in 2008 it had recently gone to a shop for carb work, instead of replacing the float bowl seal they used some kind of glop that hardened like cement and ruined the rubber seal.

Top of diaphragm was pretty much spotless.

The underside of the diaphragm is only filtered by a course inline foam filter that works great for keeping the humming birds out, not so much the gritty fine stuff.

Lots of crud found in the regular carb top chamber, I'm sure some of this stuff finds it's way down the throttle valve and into the intake tract.

None of my manuals list this as anything more than a "Diaphragm Set" this is the top spring side, not sure if thats fuel or cleaning solvent.

And where the diaphragm sits, would really like to know the proper name for this valve.

And the underside of the diaphragm that pushes on the brass pin.
