The lifan 140 has an anti-kickback mechanism, and if memory serves, that was what had me scratching my head for a bit until i figured out it needed to be held "open" to remove the cam... it is a weird spring looking "latch" type thing on the sparkplug side of the cam... removing the cam is nearly a job for three hands at once...
more than likely, it will be the anti kickback mechanism that is making the cam hard to remove...
hold this open, the cam *should* slide out...
The rockers and cam:
After you take off the caps/covers turn the head so that that the bearing(where the cam sprocket was) is facing down. Now get some needle nose plyers or similar and take out the rocker pins in the bolt holes. Undo the little bolt that holds/adjusts the rockers/valves(1x 10mm nut, one on each rocker). Then you can push out the cam. NOTE: I haven’t pulled the valve springs out.
Hi all im glad to say i got the 7mm lift cam in after slaving away for hours (about half an hour)
got the head back on and set the valve clearances. The bike idles in neutral but now when it is put into gear the bike konks out immediately after even without letting the clutch out.
i have my suspicions that it could be that the carby needs a tune but any info or advice is welcomed
Cheers
