Ok as I was trying to diagnose a starter problem, which turned out to be a blown fuse, I had pulled the tank off, disconnecting speedo cable, and line from petthingy to carb, at the carb.  After replacing fuse, checked to see if starter would work before putting tank back on.  Success, put tank back on plugged speedo back in, hooked line back on to carb.  Now I have a major fuel blockage of some kind, or I was wondering, if it could possibly air bubbles, or what I've heard vapour lock.  Seem to only be able to get bike to start by putting it on prime, constantly stalling out when releasing throttle, I think idle screw is set high, but when petthing is on position, bike just doesn't get the fuel.  What could've went wrong just from pulling the tank off?  When I am running about 50km/h - 35 miles/hr consistent pop pop pop pop backfiring.  any and all suggestions greatly appreciated

Could someone narrow down exactly where this might be, I only purposely dissconnected one hose, form the carb, could this other one pop off easily on it's own?

nevermind found it, and bike is running again......Sweet!
That line must have just popped off when we pulled the tank off.  We noticed there were some dumby hoses on top.  Should there be 2 others?

Funny, I've had this savage about three weeks now, and the exact same thing happened to me...took me, and two friends about 1/2 hour to figure it out...at least it motivated me to go buy the shop manual (which I just picked up today)...so much to learn
