i finally got the motor put back into my first bike f3 after the issues with the first one but now this motor sounds like its not all firing and plus i cant seem to get it into first gear it gos through all the other gears just fine what part or parts actually make it go between gears i have my other motor torn apart but dont know much of what im looking at so still got a broke bike. the motor cranks fine when i pull a spark plug wire out on the third cyclinder it sounds the same when its in like its not working at all the order is right when i pull it out and put a spark plug in it and start the bike the spark jumps from the plug so its sparking right could it be that the carbs are not mixing feul right any one now how to test anyn ingnition problems.
