1999 XT600E. Doesn't appear carbs have seen much attention in 60.000km.
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 (secondary) carb.
\/ Same cylinder side of the carbs, this shot is the throttle valve on the primary carb.
Carb screws are very tight and come from the factory with thread locking compound, if your screwdriver bits don't fit well now is time to buy one's that do, you can also use hex bits and a ratchet \/
\/ Rubber diaphragm should be soft and pliable with no cracks
The underside of the diaphragm draws air through a very course foam filter which fails to keep the fine gritty stuff from entering the chamber..\/
Lots of crud found in the primary carb top chamber, I'm sure some of this stuff finds it's way down the throttle valve and into the intake tract...\/
One of reasons for doing your own repairs, the previous owner sent the bike to a shop for carb work, instead of replacing the float bowl seal some kind of sealant that hardened like cement was used which ruined the rubber seal. \/
None of my manuals list this as anything more than a "Diaphragm Set" I've also been told it's the "coasting enricher" this is the top spring side, not sure if the fluid present is solvent from cleaning or old fuel............\/
And the underside of the diaphragm that pushes on the brass pin. \/
And where the diaphragm sits, the "coasting enricher"...\/
