Also, when cleaning them all you should need to do is take off the bowls, remove the main & pilot jets and spray all the jets and passages out with carb cleaner spray and compressed air. I would avoid using a wire or other hard object to clean anything since even a slight amount of damage can cause problems. Unless the carbs are really dirty or damaged which is unlikely, doing the above to all 4 and re-syncing them afterwards should get it running much better.

Awesome. Dad's been busy, and my bro has been working on the fairings. Haven't had a chance to fight with the screws. Sounds like we don't need to! Awesome, awesome! Thanks, guys. Will update. I also ordered new spark plugs.

It could be from where it was tracked or it could be because th eo rings went bad and they were leaking would be my guess

Check for cracks & replace the 2 gaskets or o-rings on the plugs.. probably a cheap fix for leaking I agree.

Ok... Carbs are cleaned and reinstalled. Bike is being very fussy about turning over. We got it to start a few times. Seems to be a fuel issue now. Tried gravity feed. It is seemingly eating gasoline. Keep adding gas, and it's gone. Won't start.

Totally posted from iPad. Sorry, bro. Haha.

So, yeah... We're at a standstill after cleaning carbs.

It will take a bit of fuel to fill all 4 bowls up initially from dry, but after that it should not be going through too much fuel running at idle or cranking over. Are you running it off the fuel tank or some other auxiliary setup? I'm curious as to how much fuel it's actually consuming while trying to start it.

Did you adjust the air/fuel screws or any of the 3 screws across the throttle linkage? If they have gotten out of sync by a fair amount it will also be difficult to get started. Also might try turning the idle screw up a bit and see if that helps at all.

Does it try to fire at all or sputter or do anything when cranking it over? After storing mine for the winter it will usually take a fair amount of cranking to get to the point where it starts to fire up and run. Sometimes 25-30 seconds of cranking before I get enough fuel to get it running. Once it does fire up and start running it idles perfectly fine.

We have a makeshift auxiliary "tank" with a funnel and a fuel filter that we just add gasoline through. The idle screw is probably off. It will sometimes start but then will choke out when you turn the throttle. If it continues to run, you can hear the bike almost trying to regulate its idle. It will be low and then rev itself and then drop, and back and forth, before cutting itself off.

Installed new spark plugs today. Old ones had carbon deposits, so we're running too rich. Decided that we are going to go ahead and sync the carbs. Hoping that fixes the issue I just described.
