Hello all from a frequent lurker and infrequent poster. I recently acquired a 2009 Kymco Agility 125 from Craigslist to use as a run-around bike and to put me in the multi-bike owner’s club (2004 Kawi KLR650). I bought it as a non-runner and have it running well for the most part now but I’m having trouble getting the idle to my liking. A little background on the scoot. Got it for $350 with 950 kilometers on the clock. It had been bought new, ridden for a month, wrecked hard enough to bend the steering stem, then stuck in a basement and not started for 5 years. I replaced the battery, drained the old fuel, flushed the tank, replaced the fuel lines and thoroughly cleaned the carb. After that it started and ran well for one day before it lost spark. After much wailing and gnashing of teeth I discovered that the CDI was bad and replaced that. It ran well for about 10 miles then died on me. Tested the battery and discovered it to be low (12.55v). Charged it and now it’s been running well overall for about a week and 150 miles. I have 2 idle problems: #1) It takes quite a while to warm up to a point where it will idle reliably. Temps are in the 75-95 degree F range here in Georgia right now. I replaced the auto bystarter (enrichener) with a plunger style manual enrichener as a part of my early trouble shooting to get the scoot running. I had read that that part fails commonly and I just don’t like the idea of not controlling the choke myself. The bike starts up immediately with the choke plunger pulled. Unfortunately this manual choke has a spring-loaded self-closing feature so I can’t just leave it idling unattended or ride off with the choke open. So generally I just ride off immediately in an effort to warm up the engine quickly. For the first 3-4 miles I have to feather the throttle at stop lights to keep it from stalling. Is this normal? I’m used to my KLR which will idle off choke almost immediately even on cold days. A couple of solutions I thought of: -Put the auto bystarter back on. I know that it automatically stays open for quite a while and I’m sure this would help the cold idle. But I really don’t like the idea of an auto choke. -Figure out a way to make the manual choke stop self-closing. -Replace the main jet and/or idle jet with a richer jet. I know that the idle on my KLR got much less finicky when I put in a richer main jet. I realize that the main jet mainly controls the mix at open throttle but I think it also has some effect on the idle as well. I think the bike is in a slightly lean condition overall as is common with factory jetting. #2) When fully warmed up the bike will idle reliably without any throttle input. However, it still occasionally sounds like it is stumbling or “missing”. I have adjusted the idle mix screw to the point that it idled at highest RPM and then turned it a quarter turn richer. I kept turning the throttle stop screw to raise the idle hoping that this would fix the stumbling/missing. I currently have it as high as it will go without engaging the clutch at idle. I’m not sure what the RPMs are as the bike doesn’t have a tach. -Is this just the way the GY6 runs? -Could it be caused by a lean condition? -Could it be caused by a float level problem? Float not allowing enough fuel and starving it or allowing too much and drowning it? Apologies for the lengthy post. I hope some of you were able to stay with me through the whole thing. Does anyone have experience with the GY6 or have any ideas to fix the idle issues?
