Hi, Had a new piston kit fitted it was the rings melted to the piston and lost compression. Now done that and bike ticks over fine but when riding at 20mph+ it starts to hunt bad if u try to keep it to a constant speed. It will accelerate to good speed but continues to hunt. Any idea's anyone? Thanks Andrew

the chamber at the bottom of the carb has a pipe connected to it that is a drain...pushing it in allows the fuel to drain..so therefore there has to be fuel in carb

the priming of the carb came in the means of me kicking it over and turning over on electric start

at the bottom of the carb there is a drain pipe and if it is pushed it allows fuel to pour out so fuel must be in chamber of carb

no nor do i!!!! What is making me think is the fact that if i pull the air filter off and put my hand over the end it feels like it is blowing not sucking

Yes vac operated....but the system has been completly drained and it has filled up by its own means

No no pipes split that i can see and yes full tank of fuel, i have had the carb off and cleaned and there is a new plug in it. Fuel is getting to carb chamber just not getting to piston!

Hi, my boy has a YQ50 Aerox and had to have it brought back home on saturday on the back of the lorry. It was running fine, it has got a 70cc mollossi kit on it and all the rest of the things to make it go fast but i can not get it to start. I have a good spark, i have fuel getting to the carb, but the spark plug does not seem to get socked after kicking over! With further investigation i took the air filter off and it feels to me that it is blowing instead of sucking which lead me to the reeds...1 side was not seating and i cannot get it to seat...is it possible the block has deformed? anyway found another block which looked fine but still cant get it to fire.....any idea's? Thanks Andrew PS the bike is a 2005 model with water cooling
