I just got my hands on a '94 XR650L but I seem to be having problems with the choke. When I pull it towards me (I think this is turning the choke on?) with the cable showing, it idles much lower than when the lever is closed (choke off?). In fact, with the lever closed all the way towards the bike, it sounds like it's fast idling or even revving slightly. Maybe I have this backwards? The bike also surges when on the throttle and I'm not sure where to start looking for that problem. Sorry if these are really stupid questions, but the last time I was on a carbed bike was in MSF and they are a complete mystery to me.
