First time playing with Carbs!
« on: April 15, 2018, 05:59:22 AM »
Hi guys the work has begun in earnest on my new XS500C.

Iíve never played with a carburettor bike before so steep learning curve! I have pulled apart one and left the other in tact in case I get a bit lost.

So far I have managed to destroy the slide diaphragm. Is it possible to replace just the rubber diaphragm and not the whole slide assembly? Looks to be 2 little plastic rings that would need to come off and go back on with new diaphragm. Any tips on this? Otherwise I have seen the JBM industries option and looks like an easy fix.

So I guess main question is now Iím ready to give the carb a bath (what cleaner do you recommend?) looking at the photos is it ok to dunk the whole lot as is now? Iíve read I have to be careful not to ruin any o rings or rubber/plastic parts but where are these... I donít see any.

Also this needle/jet whatever it is running through the middle of the carb is that supposed to come out... no slots so not sure how to do that short of grabbing with grips or pliers and donít really want to do that...

Any advice on how to finish this carb clean up and rebuild much appreciated.
