Hi i have aquired a loncin quad 125. it hasa few forward gears and reverse. the quad has no spark and i have replaced the lumb, ignition switch, cdi,coil and lead, regulator, and kill switch. there is

You have replaced it all except the problem part. The stator is a very weak part on most Chinese brands. The signal generator (coil outside the flywheel usually goes first. If you have a "peak reading volt meter this coil should put out 2-5 volts dc at cranking speed. It should also have some resistance reading(guessing in the 130 ohm range) when checked across the two leads with an ohmmeter. A dead one (open circuit) will have no reading at all.

if the crank seals were faulty your quad would'nt run at all,the problem must lie elsewhere,a complete strip down of the engine and gearbox is the only way to gain access to the seals

No drive

Please have your clutch checked. It could be wornout. Have it adjusted to engage it and drive.
If it doesn't function, you must have it replaced with a new one.
