Well, the Loncin is a good Honda/China clone engine. The clutch and front brake lever both allow the starter to turn the engine, it is a safety thing, if the bike is left in gear. The starter thing, sound like the starter is either running or the engine is turning it while its running. The starter clutch is suppose to disconnect the starter and chain drive when the engine is running. Do you have the front or top mounted starter motor?? All that stuff is behind the clutch/bell unit a 3 spring clutch in back and a chain goes to the motor gear. The stuff under the left front engine case. This is a photo of the other side, the kick start gear etc. You need special tools to take the stuff apart, you could easily spend $150 trying to fix it, or buy a new complete 4 speed engine off eBay, maybe a 125cc for $250 to $300 shipped. Some engines are for dirt bikes and have no electrical for lights and stuff. I would search, China 110cc-125cc 4 stroke super pocket bike engines.

This is the current nightmare I'm trying to figure out since I'm eating batteries.

The wiring & electrical on these bike are not real good. That bike looks a lot like my X18. My bike has had a dead battery for over 3 yrs. I turn on the key and kick start it. It runs off the stator thru the dead battery, lol. Has lights & blinkers, that get dim to bright depending on the RPMs. The lights & blinkers are illegal, not bright enough 10-15w. My road legal 150cc GY6 scooter has 12v 10w running lights & 12v 35w headlights with a high beam. I have that plus 15 pocket bikes, lol, from small to super pocket bike X18 size. An X7, 2 stroke, w/ 8" rims is a mid bike, and then the mini moto ( pocket rockets ). Air cooled and water cooled, Chinese and Euro.
Your starter or solinoid, somethings wrong, & electric is my weak point. I would charge your battery, get it running and grab the starter housing and see if the starter is still turning, should stop when you let off the starter button. I think the starter chain clutch disconnects power to the chain that goes to the starter motor by RPMs so it don't turn all the time. If your battery is being drained something is staying on all the time. Here is what you do to find a short. Disconnect the neg. battery cable, turn your key off. Put a voltmeter red & black wire between the neg post and wire, if there is current you have a short, or use a test light between. Could be your starter soilinoid is bad too, there cheap $7-$10. I just got 4 stroke starters, 1 two bolt and 1 three bolt starter online for $12.84 each & $7.95 S/H, for $20.79 each, for extra parts.
If it were me, I would take the wire off the starter to the solinoid hook the battery back up and kick start it, like I do mine. There are some real simple ways to wire the bike without all the lights and crap. PS: If you answer this you will have 3 post and can make you own thread with photos, under mid, super bikes section. No one can see you here. CAM2 will know better than me,

I have seen, online a strip down wiring harness for these engines, w/ instructions, they used them on racing bikes w/ no lights etc. Can't remember but the price was not that bad. Here is another basic wire 4 stroke dia.
