Question about 2007 Yamaha V Star 1100 Custom
I have a 2007 1100 v-star that ran great, but sat for 6 months. It would not run after that, so I cleaned the carbs as described by my clymer manuel. Now the bike will not accept throtle past 1/8 - 1/4 and then stalls. If I cover the mouth of the carb with my hand. Then it will rev, but back fires and pops back through the carb. I have adjusted the float so that they almost touch the top of the bowl and this has not changed much (before this the bike would only idle). Also, the idle air screws have been backed out 4+ turns which helped slightly. Inspite of everything it still seems lean... What should I look at next to fix this bike?
Hi and welcome to FixYa,
Initially, 2 parts of the above description are significant:
Have you tried with the air filters installed?
Good luck and thank you for asking FixYa.

Same gas? Make sure your gas is fresh.
Overall though the bike is still not getting fuel like it should. Something is not clean.
Start at the tank and make sure it flows plenty of gas. Some have screens in the bottom that can get dirty.
Next check the fuel filter and change it if you haven't in a while.
Make sure the fuel line flows plenty of fuel from the tank to the carb.
Next the carbs need stripped and soaked in cleaner. Every little passageway needs checked. You should not need to change float levels or mess with Idle air.
Make sure the choke circuit is working.
If you go through each step above starting with fresh gas it should work. If it doesn't you will have to take it to a repair shop. Taking it to a shop that specializes in bikes makes it their problem. OR you could just buy a replacement carb. Personally I think a very though clean job that includes a carb gasket kit and blowing all the passsages out and rodding them with piano wire if necessary will do the job.
