HEY mate,
I have a lifan 125 start N1234 gear box. I put an IRK on it without the oil slinger on the other side. people kept telling me that i would snap my crank. i did my research and the older lifan motors you used to buy with monster vlaves etc came out with the IRK but no slinger so if the manufacturer can produce them without an IRK and guarantee the sale of them then im fine with that personally to do it to a more modern lifan. I run a monster valve 125 with an IRK. I am 96kg and it gives you a lottle better response coming out of corners and take off's etc. in my opinion get one. you wont look back. and in the absolute worst case scenario and you do fk the motor. get another one. china bikes mate. they are cheap as chips.
 
yeah think i will. worst comes to worst and i blow it, hello 140!!
