Sprockets yx 140cc

[connorpb7]

Does anyone know if I need a different type of front sprocket for a yx 140cc or could I use a 17 tooth that is designed for a stock 110cc engine? Thanks in advancethumbsup2

You can use the 17. Your chain alignment will most likely be out. The output shaft on my OGM 140 is one quarter of an inch shorter than the stock output shaft. Just make sure when you buy it you get the right size counter shaft hole. Good luck with getting the chain straight.

If you motor is like mine the stock sprocket is a 428 not a 420 and you'll need to use the stock sorocket anyway. In two different frames my sprockets lined up using the same spacers. Would I like more run-out in the front...friggin-A yes!
