hey all have a question regarding my 1984 cm450e. I'm running on one cylinder my left side. I checked spark I have spark ,I pulled plug and checked compression with my finger seemed to have enough but will do a compression test this weekend. and I checked my float bowl drain and there's fuel in it so in pretty sure I'm getting fuel. plug is wet. so if I'm getting air, fuel, spark, conpression. why am I running on one cylinder ?
