Bicycle stalling out while rideing, please

[Testname111]

OK so my bike engine stalles out while riding from idel to accelerate but is random sometimes its fine? ( short burst stalls)
Its 1 of these problems?

Fuel system/carb
I cleaned out my fuel tank and lines and carb already still stalls
I have this carb with a #75 jet on it (it came with a #72 I think)

Or
Its because my magneto got wet and I still tried riding it..... Possibly frying the coil or bbr cdi...
I have the bikeberry racing super magneto

Or
I have a broken piston Ring possibly? But I don't seem to have a compression issue as I go 30mph fine all day and travels up hills fine still??

Magneto has a little rust on the coil area

Are you use ethanol added gas?

 

[Testname111]

No just premium gas from the station

 

[Testname111]

I didn't have these problems until my coil got wet but I guess I'll have to replace the carb and coil for good measurer

 

[curtisfox]

Relace the coil firts, then you will know if it was that or the carb...........Curt

 

[Testname111]

So to be clear a bad coil CAN have the same effect as a clogged fuel system?

 

[Testname111]

There hard to identify

 

[Sidewinder Jerry]

No just premium gas from the station

Premium octane level has nothing to do with whether ethanol has been added to the gas or not. In the USA in order to be sold as a 100% gas it must be labeled as such on the pump.

Could I have broken insides,I hear allot of clicking and it jerks my clutch allot? Its a aluminum 70cc cylinder...

(piston or piston rings, wrist pin.... Ughhh I guess I have to open up and check) I haven't opened this engine for over 2 years with very heave use I'd say I've traveled about 2-4 thousand Miles on this engine all in town WOT

 

[Testname111]

Hmmm or broken clutch barrings catching.... Ughhh I'm just have to buy a whole new engine

I'm going to try a cast-iron cylinder next... as I think it will last longer, any thoughts on that the cast iron sleeve motorcycle 70cc cylinder
