| a lot of bikes suffer from this bogging and can be rectified with tuning. Its hard to tell though, if we don't know the state you keep your bike in. If your filter is cheap shit or you let it get clogged that could be the problem. If your running a plug that is way off ideal as well that could be a factor. Check those two simple things first. An ideal plug for the 125 is the NGK CR9HRC, there are others but this is a safe choice. If your still suffering from this bogging we'll look at your air/fuel screw and pilot jet. |
