I have a 82 yamaha xj650 maxim and i cleaned out the carbs and went to start it up when done and it turned over and tried to start but then everything went dead. i turned key no lights of any kind anywhere wont crank, checked fuses, has new battery and checked that its good too but for some reason no electricity is going anywhere. what is it? starter relay? how would you check it?

Hi, Check for a fusible link near the battery on the positive side. Also check for a good ground to the frame and that the connections are shiny and bright.

my guess would be that water got into the gastank fuel line and carb you might want to check those thing fallow this link this will tell you everything you need to know about your bike and more
hi sounds like the main spindle shaft that operates the carbs has seized spray penetrating oil wd40 or similar all over the outside of the carbs giving them a good soaking leave for a good few hours
and gently try and wriggle the throttle cable till it starts to move then spray it some more if this doesnt work remove the carbs and clean them out putting penetrating oil inside the throttle bores
you will probably need to take off the lower fuel bowls and clean them out too if its been standing a long time the fuel avaporates away and your left with a lot of corrosion inside that must be cleaned
out as it will block fuel flow through the carbs
Remove the whole set together, When cleaning do not mess with any mixture screws. Pull the bowls off and clean the bowls and any jets there, If you are just cleaning you should not mess with the Synchronization. Take pictures as you pull the carbs off to be able at replace with out any trouble.
turn where floats is hanging down and adjust to where the are hanging 17/32nds turn carb upside down and mesure the top of the flaot and be sue=re it is 1/4 inch lower than the carb flaot bowels.
More likely too much air - runaway revs is indicative of too lean, not too rich. Regardless, it is your carbs causing the problem - strip them down and look - for peace of mind on an 82 bike, I would throw a rebuild kit at them.
my 82 seca which should have the same carb set up as your Maxim has a thumbscrew about in the middle of the carbs. i take off the left side cover and can reach in and turn the thumbscrew. then watch the tach as you do . Mine is set at 1050 as per my factory spec. hope that helps
