what exact kit do i need for a 1979 Yamaha exticer 250 keihin carb rebuild? i have heard that there are some kits they say work but really dont. so just making sure.

not much out there to be had regarding kits. clean the jets, passages, and bowl area and that is essentially it. dont forget the needles, gunk builds there too

look to the aftermarkets if you cant find oem parts. places like dennis kirk, shadetree, etc will have kits specific to that carb. the downside is half the diaphrams dont seem to fit correctly. the ones i have used i have been lucky and the important parts fit. seems like about half get tossed.

when you open up the pump portion of the carb pay close attention to the orientation of the diaphrams and gaskets. mark them, take pics, whatever you need to have for a later reference. it will make the task easier.

from there, as mentioned, its down to removing parts and cleaning all the passages.

Is it possible to order the diaphram from Yami?

last i checked some were still available. depends on your dealer and which warehouse they order out of. you need one that will check all resources when the parts come back as backorder.
