got me a 84 vf700f new member small problems

got the 84 vf 700 f only firing on two cylinders both coils test the same so dose pulse gens and cdi boxs nothing seem to be out of the norm but will not fire on all four the wires dont seem to be the reason nor the plugs them selfs any help will be appreciated

 

Failure of two cylinders is classic CDI failure for gen 1 and 2. Do not shoot the messenger.

 

Say you tested the CDI boxes?? How ??

 

buddy of mine told me to ohm test them, i get spark on all cylinders swithched the cdi boxs and the same side dose the same thing

 

ohm tested they are where they should be leaning toward the carbs been sitting for bout a year could be gummed up

 

i have spark on at cylinders, but the bike has been sittin for about a year so is it possible that the front set of carbs are gummed up and the back set not
sorry for the confusion

 

i will do that and let you know thanks

 

i pulled the air box off, poured a little fuel directly into the carbs,it shut off.
but i did notice that one of the carbs wasn't opening when the rest did.
i then opened the carb to the same height the rest were opened and it ran better,not like it should but better.
so i guess get the carbs rebuilt and sync ????

 

Here is a link for cleaning carbs, it is pretty easy to do and would really suggest new boots.......more of a must really. You lost me at post 5 as well but I think we are all on the same page now.
