I have a GT125R 2013 and I can’t get it to start, I’m led to believe it’s a fuel problem, when I pour fuel straight into the carb it starts but when I put everything back together again it doesn’t start, I’ve bought a new fuel pump and I’ve checked all the hoses for any blockages but there isn’t any, does anybody have any suggestions that I could try?

Hey , welcome 🙂
Please excuse my delay, I thought someone would have chimed in by now but it’s okay , we got you.
So , have you made any progress with your investigation ?
And have you checked out the tutorials for both “air” and “fuel” on this site to verify everything is in order?
Any doubts? – Just replace the tank tap (better new) , it’s on this shop.
Fuel Pump = We will get to this later, but the “tap” must defo be sending fuel in to the filter to confirm operation
Also the filter usually has an “arrow” showing correct flow direction because some owners put filters the wrong way and fuel doesn’t flow or come out. and pump will not run dry until it senses fuel. Then it sends it to the carb.

Thanks for the reply and no I haven’t had any progress. I will get a new tank tap just to be safe but when I suck on the suction pipe fuel does come out, I’ve already bought a new fuel pump for it. What way is the arrow supposed to be facing on the fuel filter? Towards the tank or towards the ground?

Try a new tap and pump , if fuel comes by the engine crank vacuum , it will fill up the fuel filter

I’ve changed the fuel pump and the tank tap, I have a little bit of fuel in my fuel filter but it’s still not starting
When you crank the bike , hold the button for 5 seconds max. Then wait 10-20 seconds for starter motor to cool down. Then do it again.
Do NOT twist throttle yet , you want the engine to draw more fuel in to the filter that’s why.
Still struggling to start?
Get someone first to lift your tank and “hold it” nicely , do not disconnect pipes or anything like that , and they must not pull the tank , just lift it nicely off its cushions and tilt it towards the back
Now you can see your airbox
Get to halfords ===> Buy “YELLOW” colour only BRADEX EASY START can.
Spray crazy amounts of it (yes go crazy with it) ===> in to the air filter ….
Now start your bike with full choke.
While starting it , you have 5 seconds to twist the throttle up & down a million times (how fast can you twist up and down?)
If it has spark, it will scream to life and the choke system will try to enrich the bike and keep it at 4k revs
After 2mins of 4k revs, slowly reduce the choke. And it should start to idle at 1500 rpm (1,000-1,2000 rpm ICE cold is OK!)
Wait 10 mins max (in this current weather before riding) , the engine should be warm and oil is hot circulating now , revs will go to 1500rpm by themselves.
Hope i made sense ?

I’ve tried that and it’s now up and running thank you for your help
Thanks for not giving up on her. Hey Warmer season is officially here, so go on a long date with her somewhere in the countryside 🙂
It doesnt drink wine but a good drink of E5 is all it needs. Not the E10 (never)
