I'm a bit stumped as to what's happening with my bike. It's a 2009 - I've been riding it for a year and purchased it with only 400 miles on it. The person who had it before me said they rebuilt the carb because it'd been sitting for a long time without being ridden.

My issue is that I'm experiencing two things that seem to signify two opposite problems. I've only been getting about 50 miles on a full tank before I have to refill which would seem to mean that I'm running rich; at the same time, the bikes been running really clunky when I push the choke in - it runs much better and much more smoothly with the choke out, which would seem to mean that it's running lean.

I'm not sure how to deal with both of these problems. I've changed the Petcock to the Raptor.

Air leak?...  Is the vacuum tube outlet capped?...

Thanks all - this is really helpful. The vacuum line looks like it's still plugged...I'll take a look at the carb to make sure the jets are clean and let you all know what happens.
