First apologies if this is a repost. I did a search but can't find any post that actually says how to do this.. I have also looked in the manual and either I am not reading it correctly or it is just kind of hidden amongst the other information there. I want to be able to loosen a screw and drain the carburator on my YZ450 without removing the carby or anything drastic like that.. As there are lots of adjustment screws etc. I want to make sure I get the correct one.. Can anybody explain clearly or with pictures how I can drain the carby without removing it?
