So I'm still going through my 01 I recently picked up and I'm not sure if it's a bike problem or the bike owner not knowing &%$#@! he's doing. So, after cleaning and oiling my filter, I started the bike up last night, let it idle for about 2 minutes full choke, then closed the choke and started blipping the throttle, it would blip ok, but it seemed to 'hang' at the top of the idle for an extra second or so, then settle back down. Is this normal? or should it instantly drop back down? Could it be a return spring? (if there is one?) Next, when riding the bike, starting off, it's fine but it seems to bog/stumble slightly after about 1/4 throttle opening. Could all this be because the bike isn't good and warmed up? I live downtown so it's kinda hard to really stretch the legs on this thing. I also noticed that my right side radiator down tube is SUPER close to my exhaust pipe. I'm guessing it will melt, but I haven't had a change to get the bike hot. Is it possible the pipe is bent? Any ideas about how much clearance I need at this spot? Sorry for the rambling questions. Thanks guys!
