Bike will only idle on full choke.

My 08 with 5900 miles sat for 6 mths and now it'll only idle roughly on full choke and it only idles low 1-2k. If you touch the choke or throttle it dies. I even let it idle for 30 mins and the fans came on so I know it was warm enough to be taken off choke but it still dies.

How I trouble shot it-
- New gas with seafoam = nothing.
- Drained most gas and ran high concentrate of seafoam = nothing.
- Pulled carbs. Jets and bowls looked pristine. No film or buildup whatsoever.
- Check fuel filter and they were also clean.

I'm out of ideas. Can anyone help? I have the bike completely apart and don't want to pay to fix something I am capable of. I just don't know what's wrong with it. Thanks!

The pilot jets and possibly the needle and main jets are clogged. Therefore the carbs need to be removed and physically cleaned period.

my 2012 with 7 miles had a plugged pilot jet. disclaimer: the bike was completely disassembled and sat for a little while. the point is, these pilot jets have TINY inside diameters and get plugged very easy. dont know how it happened in my case.

i checked everything else, and finally found it using a IR temp gun on the exh pipes. one was def cooler than the other.

good news, the repair doesnt cost anything. bad news, pulling the carbs are a royal PITA. found that loosening the airbox and removing the LH rubber carb adaptor helps.

once apart, remove the float bowl covers and take out the pilot jet (the little one next to the main jet). you should be able to see light through it. if not, compressed air. or take a tiny brissle from a fine wire brush and push it through.

I agree on it being a PITA. I had already taken the carbs out before I posted this thread. I assumed nothing was clogged when I opened them. But after some research I tested the pilot jets with them still attached on the carb buy spraying carb cleaner through it and looking for spray on the other end behind the throttle plate. Sure enough nothing came out. So I'm hoping this is the issue.

When reinstalling the jets should they be torque'd to any spec or just fit snuggly.
