Ok guys I bought this a year or so ago and I think I heard X12 around the bend somewhere. What is it? I got it running so that's a bonus but I don't see a shifter anywhere, so I can only get it to go 5/10 mph cause I can't shift up.

1. Identify me.
2. Help me figure out where the hell the clutch is and get it fixed.
3. Bask in my praise.

Can we see the other side?

 

[milne.james]

Here you go.

Those are kinda crappy but hopefully you can tell.

Thats an x12................

 

[milne.james]

So there is no shifter or clutch,what do I need to do to shift?

 

[BlitzMInc]

looks like an auto, no shift, if there was one it would be above the kickstand on a shaft
the cc is stamped on the black cylinder as __cm3

 

[milne.james]

Ok then what would cause it not to auto shift? Would I feel it?

 

[BlitzMInc]

no its one long gear, you might have clutch issues keeping it from going faster like if its not grabbing enough
i know the fix is behind the clutch cover but i forgot what it was
my 70cc x6 could do 45

 

[milne.james]

I found the stator but where is the clutch cover?

 

[CAM2]

That looks like a 110cc full auto engine put in there in place of the 70cc semi-auto engines they came with.........Unless its a newer model x12...

As far as finding a clutch cover,,,youll only find a sidecase cover,,,the clutch adjustment screw sticks out of the sidecase cover secured with a jambnut..............If the previous owner didnt use wetclutch safe oil its most likely the clutch is mush or burnt up.............

So there is no shifter or clutch,what do I need to do to shift?

Its just twist n go.......like a moped............It doesnt shift at all..One speed only............

 

[milne.james]

CAM2, forgive my ignorance, I'm just learning this stuff. That thumbnail you sent, should I take off the whole side piece to the engine to access the clutch and see if its burnt up?

Not unless you want to...in the pic you see a slotted screw with a nut coming from the case,,loosen the nut and turn the slotted screw out about 1/4 turn tighten the nut and try......if it grabs better try a 1/4 turn more and retry again...If you get good clutch grab again change the oil and youll be good to go....if you cant get it to stop slipping then remove the cover and remove the full auto clutchpack with a clutch removal tool......

Cam2, is that what the clutch looks like on my 125cc Auto ATV. If so, looks like if you stiffen the shoe springs like a Cag clutch it would let the engine rev more before take off, right?? The way mine is now, can't get enough revvs to get a good start.

Yes exactly EPR...Its a big heavy unbalanced piece of work..The stallspeed rate of grab can be adjusted with that screw,,,,A head breather mod will help out alot get good bottomend takeoff boost............

I want ur bike so bad! It's super nice!

 

[EPR]

I have been looking at the adjustment screw with lock nut, but was not sure if I should mess with it, now I know. First thing I though of was drilling holes in the clutch arms,lol. I have the Cable TV fitting that I drilled out that was in your breather mod, for the X18, now I need one for the 110cc dirt bike and the ATV. Going to change the China oil to real motorcycle oil soon. Wonder if anyone sells heaver clutch springs for the auto trans.

The clutch arms can be lightened and the springs can be replaced with stiffer.......On my x22 I modded my full auto clutch with stiffer springs from my 5b clutch and static balanced the whole clutch to decrease vibes

 

[BlitzMInc]

epr, you never changed the oil??

 

[EPR]

The ATV is brand new, only a couple of hours of running time. My other two 110s I did the same thing. I use it for brake in oil, then replace it.
