Benihana Posted March 25, 2009 Posted March 25, 2009 Hi guys! New member here, just brought my first Yamaha and first bike, a lovely XT125X with barely 3,100 miles on the clock. I had a quick go on it before buying it and ran fine, and started up several times after, however coming to take it out for the first time for a serious run and while the starter ticks the engine over, it won't start. (Charged battery overnight) Looking underneath the engine there is a small transparent pipe coming from the fuel tank but seems to end unconnected. I'm pretty sure this is why I'm having problems, but cannot seem to find out where it should go. Does anyone have any pictures that I could use? Or a guide that would help me re-unite the pipe with its rightful location? Thanks to all in advance!
Moderator Airhead Posted March 26, 2009 Moderator Posted March 26, 2009 Hi, I'm not familiar but would hazard a guess thet that pipe you are seeing is either the fuel tank vent pipe or oveflow (for over filling) pipe and therefore not the cause of your problem. are you using the choke properly to start the bike? it is usual to use choke and little or no throttle until the motor is running.
Benihana Posted March 26, 2009 Author Posted March 26, 2009 After a bit moore googling, i think you might be right about it being a vent pipe. When the seller showed me the bike he started it with the choke (pulling it all the way towards him) then after a minute or two moved it half way back, and then fully in. The last time I got it to start i gave the throttle a quick twist which seemed to get it going. Could it be that I've flooded the engine? I was going to take the spark plug out and check that it wasn't wet, should I try starting it with the plug out to see if it sparks? Appreciate the help!
Moderator Airhead Posted March 26, 2009 Moderator Posted March 26, 2009 Yes you could check for spark but I expect that will be ok, its a new bike to you, It could just be that you havnt learned the Knack to starting it yet. If the plug is wet, leave it out for a while to dry out and try again.
Benihana Posted March 29, 2009 Author Posted March 29, 2009 Just incase anyone reads this, I sorted the problem. Stupidly the fault was my own, I added some petrol that I later found to have water in. Water being heavier than petrol, sunk to the bottom and got in the carb. After draining the petrol tank and drying out the carb the bike is once again running fine. At least my stupidity forced me to learn more about my bike
