I got a 2001 vulcan 750. It seems like it runs good but I noticed the choke doesnt work. When I give it choke it wont start at all. I noticed the RPM's dont rise when the choke is applied, I need to look into this issue. So I'm new to motorcycles and what I've been doing was adjusting the idle on the motor.. I was told today to not do that.. =S. So my question is what should I check to fix this choke issue? Also, how many RPM's should my motorcycle idle at when warmed up. Thanks for the help guys!
