ATV-X21 125cc ATV
Yes , i was wondering if anyone could assist me on figuring out why my 4 wheeler is not capable of doing donuts. When i give it full throttle is just dies. But reverse it spins tires just not forward. I got the 125c hunter chinese ATV.
I have taken the carb off and cleaned it and made sure nothing was in there so thats off the menu , i adjusted the carb to best i could. Something else is making it where it doesn't do 100% power at full throttle and dies. Would like opinions or if you know of any parts that can replace easily and cheaply would be awesome to make this ATV a bit more enjoyable. Agian it's the 125 cc hunter model with the back and front rack and headlights. |

My guess is that it takes off in reverse due to steeper gearing. It isn't making the necessary torque to take off in a higher gear.
I'm betting that the stock exhaust is very restrictive and that the carb is set up quite lean.

gearing in reverse is usaly lower..
also weight transfur.... when taking off forward the weight transfurs to the rear wheels... taking off in reverse the weight is transfured to the front wheels making the rear lighter / less traction... ...

The carb selection will depend upon what's on there now. Can you show us a pic of the carb? Show us the air box as well.

This could be a nice upgrade from your existing carb, but it's up to you to confirm measurements: http://www.ebay.com/itm/Mikuni-Carbu...NXa5xM&vxp=mtr
Once it's in your hands, you may have to swap the main or slow jets (or both) to make it perfect. What is the diameter of your existing mid pipe, right where it meets the muffler?
