Lifan Piston Rings

Recommended Posts

Hey i have a Lifan 110cc motor on my xr70and well today i notice that my bike has smoke coming out of the crankcase breather so i didnt really think of it as a big deal so i drain the oil thinking there was too much and that was why it was smoking, added new oil and started it up and its still smoking? so i called up this place by my house called the Dirtshop and they said that i probably have a broken piston ring. But to make things short i was mostly wondering if the BBR 110cc kit piston rings would fit on my 110cc lifan piston because i cant find piston rings for this annnnnyyy where thanks.

I'm not sure but I didn't think bad piston rings would make smoke come out the crankcase breather? If you measure it up( the rings) your local dealer could look for a matching ring? From a different bike.

ATC 110 I'd bet. Get the bore and stroke of your bike and compare it to the ATC 110. Bet it is the same.

Also I think the SDG and Xtreme 107's use the same rings. They have Lifan motors too, no?

yea well i took apart my top end and the rings are perfectly fine and then i thought that my exhaust valve could be leaking beacuse rite as i start up my motor exhaust comes out of that breather and i know its now burning oil in the trans becuase it wouldnt start shooting the smoke out rite away. but i could be wrong if anyone else could help me thatd be great im just getting realllll pissed off with this bike its the second motor and this lifan is only 3 months old. (i wouldnt reccomend it)

If you're getting smoke out of the crankcase its blowby - bad rings, bad piston or bad cylinder unless you have something really weird like a hole in the head or exhaust port. Bad valves won't leak into the crankcase. Do a compression test.
