So I havn't rode my bike since last Sunday as i needed to get my new tires mounted. Pull the bike out this morning, pull the choke out and start it up. First thing i notice is the bike is way more quiet than what it should be with the choke out, so I let it warm up for a few, push the choke in and take it around the block. Oh crap, the bike wants to die in first at the stop sign. I've got to give it a lot of throttle to get going and in first at WOT it's only turning about 3500 rpms. I changed the plugs but it is still doing it, any suggestions would be much appreciated.
