This has plagued me for ages, and is getting worse as the weather warms up. Bike: 2005 Suzuki VL250 Intruder When it's hot, and I idle at a light for (usually) more than 30 seconds, it LOVES to stall. About 60% of the time high-revving will prevent it....but I look like a jerk and that isn't good for the bike. If it dies, restarting only happens with it at WOT and it struggles to catch. I have replaced the plugs and battery, power is good so nothing wrong with stator or regulator. I am leaning towards either a pilot jet issue, or coils. I think it's more the jet because it goes great when riding....but on one ride to work I did have it cough on me a couple of times like it lost spark....but hasn't since then. It could be the coils from ambient heat pooling when not moving, and then the air cooling them down as I am moving. Any ideas?
