    New need help

    There's a seal in the stator backing plate, you need to remove the flywheel and remove the old seal on the crank and replace.

    140 lifan no clutch

    It must be the pin or the pin isn't in the clutch arm socket mate, did the bearing go back in the clutch plate?

    Crossfire 140 vs Thumpstar 140

    VM22 for a 140, the 27 is a tad bigger but the mikuni is a much better carby.

    Best carb opinions for 160cc

    The 26mm mikuni has a mixture screw on the bottom of the carby, if you turn the carb upside down you will see it. The mikuni 30mm carb jetting is pretty good with a 160, the 26 will not give you topend revs.

    Bike goes when choke flipped off without engageing throttle.

    Sounds like its sucking air at either ends of the intake manifold.

    The OKO 26mm is perfect for this motor, standard jetting works well but if you want to tweak it DHZ sells jets for it too. OKO PWK 26mm Flat Slide Race Carburettor Kit

    Lifan 70cc

    I've seen them as high as 150psi, under 100psi they run terrible if they run at all.

    Converting 5 pin AC CDI to 4 Pin DC CDI any good?

    It's very common to hook the killswitch up to stop the motor thru the stator pickup mate. Won't hurt anything. If it ain't broke, break it.

    Converting 5 pin AC CDI to 4 Pin DC CDI any good?

    As this pic here shows blue with white in a 4 pin is the main wire to join to your killswitch but you can also use the black with yellow stripe. If it ain't broke, break it.

    Crf50 is Honda. Don't by a genuine Honda seat just buy a Chinese crf50 seat. You can get the high crf50 seat or the low crf50 seat. The high seat has more padding for a ya nuts so I go those. If it ain't broke, break it is just my signature on miniriders mate. In other words thrash the...

    Converting 5 pin AC CDI to 4 Pin DC CDI any good?

    The black with white stripe killswitch wire will need to be joined to the black with yellow stripe wire for the coil positive. Then just run the green wire to the other greens or earth on the frame or engine. Without worrying to much about the black with red stripe get a multimeter and put it...

    It's a standard China bike mate. But the frame setup is based around crf 50 style plastics and seat. So a copy crf50 seat will fit. If it ain't broke, break it.

    HELP ME PLEASE

    It'll be cool mate. Like motodevo said and also remove the plug nd kick it over a few times in case there is excess oil in the combustion chamber. Could create more compression and bend a valve. If it ain't broke, break it.

    Baja Designs CRF50 stator in Piranha 140?

    As long as the yx140 stator supports lighting it will be fine. Id be more worried about having a very good quality battery and charging system as the stator powers the battery for the headlight on them as opposed to China quads where the stator supplies the lights power so they dim when I'd...
