Over heating maybe ??

[qwerty243]

Can someone help identifiy what could be causing this problem.

After riding for a couple hours today my bike started to run really sh!t like back firing, spluttering and stalling. so i stop and try and start my bike and it wont, kinda of sounded flooded after trying to start it. anyway i end up putting the choke on and it starts right up but when i take it off it dies instantly. even though my bikes really hot. that was confusing because i thought the purpose of a choke is for a cold engine ? so i left the choke on so i could ride it and it sounded horrible like i had kicked it in its metaphorical ballsack. i take the choke off and it stays alive but then it happens again a couple times so i end up leaving the engine off for a bit maybe 5- 10 mins and i managed to ride it home fairly normaly.

This is problem is happening after riding for a while at half throttle so dose mean my needle thingo need adjusting ? im assuming thats whats in use at around half throttle.

other than that i was thinking over heating but i really dont know.
My bikes a x-motos 250cc air cooled with a pz30mm carby

Sounds to me like your main jet has dirt in it.

Maybe its a your jets.

Sounds like your carb isn´t really a good unit and its running too lean .....start to jet it way more rich and go from there

yeah ill have to take the carburetor and air filter off and give them a good clean also see what size jets i have. hopefully everything will be all good after that.

Also i changed my oil today i've only rode it twice since i changed the shipping oil out and it was really grey i read that its because of water, i may have rode through a huge puddle the other day lol. i was going way to fast to avoid it, i made it through.. just. i now take great care avoiding ponds... :11doh:

Don´t you worry about the oil...when a engine is new thats rather frequent Change the oil after every five hours and in notime it will be settled to a normal color when you change it.
