hello,

Just bought a motorcycle and it came with a pocket bike. No idea what kind of pocket bike it is. All i know is that it says R6 on the side. I've got it running a couple of times. but now I'm having problems with the carb. seems like no gas is getting into the cylinder though i've cleaned the carb out. Any help would be appreciated! and if you can tell me what bike I have that is appreciated as well!

When i took the carburetor apart. i kinda unscrewed the needle that my finger is pointing to. Does anyone know how far in its supposed to be screwed?

Thats an X6 pocketbike...........factory setting on the side screw is 1 1/2 turns out...

Thanks! Do you know of any good websites to buy parts from? I think I'm gonna buy a new carb for this thing. Though I'm still at a loss on what cc it is

Its most likely a 49cc...It has a CVT.......

 

[ascendantchaos]

How about the carb size? how or where can i find out what mm it is?

depending on what size the cylinder says it could be either a pz15 or pz16 carb whether its 50 or 70cc...i know its not a pz19 for a 110cc..

If its a 49cc-50cc 2stroke Amazon.com had the 49cc 2stroke carb for $16-17 plus shipping. Do a search for 49cc pocket bike. I just ordered a pull start for $10.50 and 4.50 shipping.

Welcome to PBP forum. I used to live in TX. Miss it a lot. You have a nice looking bike.

 

[ascendantchaos]

Thanks RepoBike

Does anyone know where to find parts for this x6? I'm trying to find a horn/turn signal/headlight control assembly. I found the throttle control assembly but cant pin down the left hand controls. any Ideers?

As for figuring out what cc the bike is, I've been busy with school I've not had the time to check it out, I'll do that this weekend and let ya'll know what I find.

It's probably a 43 or 49cc piston port. That carb is used on alot of bikes. Its a copy 15mm Walbro WYK pumper carb. Walbro WT 603 & 813 carbs work good to with minor mods. We then put a V-stack with choke plate, and cone or foam air filter.

My apologies for posting all these questions on my Intro thread. (I'm sure these questions have been answered somewhere in the forum already, however i'm not very successful in finding them. I am still new to this whole forum experience so thanks for bearing with me.)

So I attempted to find the model number on the engine, however I was unsuccessful. Is there another way to figure out the engine size? the only thing i saw on the engine itself was the number six. (first picture)

these are pictures of the engine [top, left, front]

Also, Lets just say it is a 49cc engine, what should I gap the spark plug to?
I've read around 0.6 to 0.7 mm or 0.0236 to 0.0276 inches is this correct?

I know this sounds dumb but aside from turning the key, priming the fuel and utilizing the choke is there anything else i should do to start the bike?

Make sure you have a good strong spark on the plug. What i do to check is remove the plug from the head then connect it to to plug wire. Then lay it on top of the head so it has a ground. Then pull the pull start a few times. If the spark is weak it wont run. So just make sure its nice and bright. doing this will save you a big headache later down the road. On my first bike i mess with everything for days. The whole time i was thinking it was my carb. But it ended up being a weak coil. It would spark but it was just to weak to run.

If wanna learn anything about these engines just look up EPR, CAM2 and Swheels posts. Those 3 are the masters of these 2strokers.

Alot of people blame a bad running engine on the carb and it's somethimg else, have done it myself, so don't feel bad. A weak spark on the outside will be even worse under compression inside the cyld.

I dont think i'm getting any spark on the plug at all. I've tried as you suggested and i'm not seeing a spark jump on the plug at all. I've tried using a multimeter but the readings are not constant. I believe it may be the spark plug wire itself.

there is a new development. If i hold the left hand brake, and press the yellow button on the right handle I'm assuming the starter button, the engine continues to turn (or the starter does maybe both) however the engine does not start. my gas lines are full of gas, and my primer bulb seems to be working. Ive tried using starter fluid to see if it was a gas problem though i dont think it is. I believe it may be the spark plug wire since its not igniting in the cylinder. I could try and post a video later today if that would help diagnose this problem

If theres no spark on the plug and the plug is grounded good to head when using the e start or the pull start means that the coil has gone bad or on the bottom of the coil where the mag from the flywheel passes by it. If that part of the coil pack is to gummed up it wont spark. Just take a rag and wipe it off good. If it uses the some coil as mine the plug wire and coil is molded together. There $15 brand new on ebay and amazon.com

You didnt see any melted wires did you? my first bike i got it. The 2wires that goto the coil to shut it down were melted together. I cut them off and the bike started right up. That also will not let the coil spark.

When reinstalling the coil. You'll need a good aur gap inbetween the coil and flywheel. I was told to use some like a index card as a spacer. Iv used other thing like a index card. But it works great for getting the right spaceing.

 

[EPR]

My guess is the coil, there crap new so they don't last along time and your bike is used. My 49cc piston port coil, the wire don't come off.
You might try taking the plug boot off and put the spring on the wire near the engine to see if it sparks. I would take the plastic engine cover off and look at the coil. If the flywheel or coil arms are rusted, clean them and reset your coil gap. The flywheel gap is .020" the plug .025" to .030"

Are you checking with a new sparkplug?...Plugs can just stop sparking too.....Airgap between the flywheel and the coil is pretty crucial...too tight or too loose of a gap and the coil will cease to spark........The coilbody has to be grounded good to the engine case too...

I finally got a video. i know i said hold the clutch in.. i meant hold the rear brake handle.
here is the video

If it doesnt show up, just search for "Pocketbike x6 start attempt" in youtube. and it should come up..

 

[ascendantchaos]

I also ordered a sparkplug coil that Should be the correct one. and as an added measure i ordered a new carb as well. [since i couldnt find a rebuild kit, and it was only about 14 bucks.]

Cool deal. Keep us posted about your bike.
