Hey guys,

My friend just picked up an X1, just like this one here, http://sell.bizrice.com/upload/20120329/Ninja_X1_Bikes.jpg , for $50. The bike supposedly runs, although we have not been able to get it to start. It seems the person who owned it cut a lot of wires, and had no electric charger. We are not small engine experts, but figured with the mass amounts of knowledge on the internet we could figure it out.

I am having a hard time finding anything but parts for these X1's, and I'm not even sure who makes it. We pulled the spark plug, and it wasn't sparking. We picked up a new plug from walmart that is also not sparking. When putting a screwdriver into the spark plug wire, and grounding out the screwdriver on the engine, if i touch the engine with my other hand, I do get shocked, which leads me to believe the wire may not be working 100%, or we have another bad plug somehow (not likely).

My questions are this, are there any decent websites, manuals, forums for repair on these bikes, or pocket bikes in general? Does the X1 need all the wiring? We tried removing the battery and hooking it to a battery charger, but the battery charger never recognized the battery. Is the wiring just for the lights, or what else is it for? Can we start the bike with no charge on the battery, and no charger? We have no need for signals, and figured we'd rip out the wiring, but are unsure what it all does, as I assume some of it is needed for the bike to run. Is there a kill switch which may cause the bike to not be starting?

Thanks for everyone's help! We really appreciate it!

Welcome to the site......

Sounds like you have a bad coil........You can rip off all the wiring off the bike and itll still run like a weedeater...You can utilize the pushbutton on the throttle to use as a killswitch with the wire coming from the fancase cover by the transmission.......Good Luck.

Update - I was able to remove the charging peice, with the fuse by unhooking the wires, and I now have spark. Bike still isn't starting, I know nothing about carburetors but I guess that's my next step now that I know we're getting spark. The carb doesn't require any electricity, correct?

The carb is electric free......Take some gas n oil mix and put a couple tablespoons of fuel into the cylinder through the sparkplug hole and see if it pops or starts....If so try richening the lowspeed needle..

The lowspeed needle is in the center of the brass slotted screw holding down the carb rotator,,,You need a jewelers screwdriver to adjust it...

The person who owned this bike before us ripped it to peices, wires cut, lights rewired etc. I am seriously wondering if they used a gas/oil mixture, or if they just ignorantly put in gas. Is there any way to tell, I figured it would be a little thicker than gas, or have a different color, but since it's a 20:1 ratio, I guess it'd be hard to tell.

20:1 ratio is a really oilly mix....You will see some color change,,,Besides 20:1 is only for break-in...After break-in the fuel should be mixed to 40:1 which is lesser oil....

We tried to pour some fuel directly into the spark plug hole, and tried starting with no luck. No popping or anything.

If the carb is not electric, why wouldn't the throttle work? I see that the throttle opens the carb, which should work if there is no wiring. I guess I don't understand what you're saying. I believe that you're saying that if I were to remove all electrical wiring, the bike would run, but always at full throttle, with only on, or off. Is this correct?

Oh boy you give the chinese too much credit for such a dirt cheap low quality pocketbike.........Its a pumper carb that pumps fuel into the engine like a fuel injector but it works through engine pulse....

Do you see any wires or plugs on the carb?????????When I look at my X1 carbs alls I see hooked to my carb is two fuellines and a throttle cable

Do you have a gas powered weedeater in your garage????

If so the X1 starts and runs the same way whether or not you remove the wiring..You de-activate the killswitch ,,pump the primer bulb,,set the choke and pullstart it til it starts.........You dont need all that wiring to get it to run.....The chinese added a generator and an electric starter to complicate things aswell as run lighting,,horn and gauges which are very problematic an worthless......

Ive had close to a doxen X1's and when I owned and ran them the only wiring that was on them was a sparkplug wire and two killswitch wires running to the pushbutton on the throttle...I stripped off the generator/e-starter combo,switches,wiring and battery to gain performance and to drop a lil weight...........

If you put gas down the sparkplug hole and it did nothing get a new sparkplug or coil.

Okay guys, here's my update. I am by no means a small engines expert. We have still been unable to get the engine to pop, or even sound like it's trying to start. As stated previously, the person who owned the bike before took horrible care of it, and had cut lots of wires. The bike currently does not have a battery in it, is the batter required to make it run (from what I understand, it doesn't). The bike is leaking fuel everywhere, and seems to be leaking more when we try to turn start it with the pull string. I have attached some pictures here.

When pulling the string to ensure the piston is moving, it seems to be spitting out fuel from under the piston. Is this normal? Should there be fuel under the piston? I guess something has to lubricate it. Before we were not getting a spark, we replaced the spark plug, but replaced it with a similar size one from walmart for small engines. We have confirmed that it is sparking. If it's sparking, that should work, it doesn't have to be a specific plug, as long as it threads in, and sparks, correct?

Obviously the gaskets on the engine all appear to be bad, and need replaced, but i didn't think this would cause it to not start, maybe I'm wrong. I'm trying to at least get some sign that the engine is trying to start. If we're getting spark on the plug, the piston is moving, and we poured fuel into the spark plug hole, I just don't understand why it wouldn't ignite, but again, I don't know a ton about engines. Any help or suggestions would be greatly appreciated!

Airleaks cause starting and running problems most definately because the air leak changes the air to fuel ratio............

The initial problem is most likely a bad coil them the old owner took the bike apart over and over wrecking the carb gaskets refusing to beleive the coil is bad...........The bikes are chinese made and coils dont last very long after a certain age.........

I have a whole box of coils that spark and dont have enough power to fire an engine under compression................

get a new coil,,carb gaskets and a carb,,,Then the bike will run really well if theres plenty of compression...........
