Has the bike been sitting for a while? If yes, then the carb needs a PROFESSIONAL cleaning..there are too many little passages and jets that must be perfectly clean for it to run! NOT to mention the fuel passage into the carb..(Needle and seat)..
If this is the situation... get it cleaned and enjoy the ride...
wear a helmet - even if your state law doesn't require it!!
you say you cleaned the carbs, but did you pull and clean the jets ? they are very very tiny holes, and take like nothing to plug them. pull the jets and run a wire from a wire brush thru them, should start for you now
the fuel inthe carby will have gone off and blocked the pilot jet. you will need to remove carb and clean out. to do this you need to remove seat,tank, raise the rear sub frame so you can get out carb. once carb removed you will need to clean out needle valve, main & pilot jet, may even need to put fine wire through pilot jet to clear blocked jet. reassemble and bike should run,I do a 4 a week with this problem.
Intruder carbs are notorious for this issue. What you have going on is that the needle seat has become worn out. The problem is, that this carb was designed with pressed in needle seats that cannot be removed. You will need to search online for an intruder carb rebuilder that can press in the seats for you, as well as change the seals, replace the needle, check the diapragm and jets, and replace/clean the floats. OR, you can try to find new carbs online from a wrecked or used Intruder 1500 VL.
the carbs are bunged up with varnish off the petrol that was left in them when you layed the bike up on the bottom of the carbs is a small screw undo them to drain the carbs out and hope that new petrol getting to them will clean them so it will start if this dont work you will need to strip the float boles off and try to clean out the running jets with carb cleaner, you should never leave a bike with full carbs if your going to let it stand for months all ways turn off the fule and run them dry first,,, you may get away with filling all the carbs with carb cleaner and letting it stand for a day or so, this may clean out the jets but you will need to drain the carbs of carb cleaner and refill them with petrol before you try to start the bike up
Google babbitts sports center.com then click on buy oem parts and then select your specific bike. A parts diagram will come up, change the page from 'air cleaner' to 'carburetor' on the drop down menu and you can see your carb assembly. Hope this helps...
I would take the carb off and clean the jets. I had a bike that if i didnt ad stabil to it, the gas would varnish in just about a month. It also depends on what kind of gas you put in there and if you fill the tank up so condensation doesnt get in there.
