Some basic carb question

[gregwillclark]

All,


Forgive me if this has been covered before, but I have some question regarding the FZS600 carbs, mine have been stripped down and cleaned - I was wondering why 1 of the 3 jets is a blank i.e. no hole? According to (http://www.yamahamotorcyclespares.co.uk/...etor?uID=0) its item number 8, Jet Main (-0).


I can see the other two listed as Jet main (-115) and Jet Pilot (-12.5). Why is one blanked??


Also I can see a fourth jet listed, item 6, Jet Main (-130), what does this do?


Regards
Greg

ignore, can see  now its the air jet on the air intake of the carb.
