GB500 Won't always idle / 'pops and stops'

[Max Preload]

Well, it's not automatic in that it doesn't allow for any variation from factory specs. It's preset with the advance based solely on engine speed, not load (throttle position) and doesn't get feedback to retard timing like a closed loop engine management system with a knock sensor does. It's just engine speed = set degrees of timing advance.

That said, even closed loop factory engine management systems often won't allow sufficient deviation from design baselines as would be required for a modified engine.

All ya fuses and connections, as these can become dirty or poorly connected, they can cause high resistance and cause the bike not to spark properly. I ran my xj for a week when it was cutting off under low revs to find out the fuse was bearly sitting in there, meaning it realy needed 13.4-14 volts to actually go fine instead of the standard 12.5-13 v when idling.

Finally, The whole thing is just about over.

It still pops and stops on idle, we can't figure out whats doing it, replacing the carb definitly made a good difference but its still not right.

It was lacking some serious power, KG replaced almost every bloody thing on the bike until last night we found that at the upper end of the exhaust there was a very restrictive.

Just took it for a spin, and the damn thing felt like it wanted to rip me' nuts off! (in a good way).
