im at a loss. 2004 EC300, recent complete new topend(S3 barrel piston & head). went for a nice 4 hr ride. came home washed the bike put it away till the next weekend when the next ride was planned, got to the track and bike dead. checked spark none so thought plug was gone. replaced plug nothing still. stuffed around with wires removed all kill switch wires from bike(unpluged from CDI), sanded earth places. now have good strong spark(will junp 5mm plus the plug gap and crisp blue) thought sweet im off but got nothing. pulled carby cleaned and checked float level, put back together. i have nice strong spark, i have fuel, i have compression(170psi roughly) but i have no bang. i am getting to the point of pouring fuel over it and burning it. can anyone give me any insight TIA
