Low RPM hesitation
I have a 2002 vn50, all stock. Other than some difficulty in starting the bike (MF battery + iridium plugs helped a little), its always run perfectly fine. It has sat outside, covered, for the past 2-3 weeks and I just went out to take it on a ride. Once I started it with no choke, it idled a little at 1100 and then sputtered and died. I started it with half choke and it immediately ran way up to 3000 rpms, so I backed off the choke. It dropped down to its idle at 1100 and sputtered and died again. I started it once more and kept on the throttle until it warmed up and would idle fine. I kept messing with the idle adjustment once it was warmed up but ended up adjusting the idle back to where it was at 1100 rpms or so. If I get on the throttle, it sputters and hesitates real bad for a few seconds then the RPMs suddenly kick up (to where they should be at that throttle position) and it's fine. When I let off the throttle, it stays up at around 3000 RPMs for about 5-10 seconds before finally backing down to idle 1100. I went for a few laps around campus to see if maybe it just needed to ride for a while, but on all my takeoffs, following the procedure i've been doing for the past 3-4 months, it would hesitate and sputter below 2000 RPMs and then finally kick up. If I slowed down, in gear, to under 2000 RPMs, it would start sputtering again. I also smell fuel around my bike while idling (cant tell while riding, too much wind), more than usual.
I always suspected the carbs are dirty but I have no space or time to do carbs myself as I've never done them before.
Does anyone have any ideas?
I hate to try to scrape up the money to put it in the shop to get the carbs cleaned (and rebuilt?) but i might have to...
