as long as your ogm 140 has an aluminum cylinder you can use the tb 160 cc kit and a tb300 cam
we have these in stock
let me know if you need more help

If it has the cast cylinder, get the TB 146 cylinder, a 57mm piston with 15mm wrist pin, 2mm akunar spacer for between the cylinder and cases, TB 300 cam and heavy valve springs. Takes the motor to 152 c.c.'s and it will have plenty of power.

The OGM 140 with a cast cylinder is a Lifan and the YX 140 has an aluminum cylinder. The Lifan has a longer stock so the cylinder is longer, 59 mm stroke if I remember correct.

I thought the Lifan 140 was a longer stroke?
