| Not sure about the misfire, but as for the stalling, my experiences tell me that if i warm her up slowly (without exceeding 2000rpm, prefferably lower) and only jump on once the temp is up to about 50 I don't have any problems. If i jump on before she's up to temp or rev too high on warm-up I have problems with stalling.
Just my experience, dunno if anyone else can relate to this?
