Hi im a noob in need of some help ..
I have a v-Clic gy6 2008 which i bought cheap as non runner to repair
I renewed random stuff including the carb , piston and rings , spark plug and coil
bought a cdi but was wrong type .. mine is dc so existing one is still on
Set valves and fresh fuel
I think the problem is either the stator , pickup or cdi
Im new to electrics but done some stator tests using a cheap multimeter maybe you can tell me what they mean
May have tested wrong lol
my connector from the stator has 2 wires instead of 3 ( yellow & white )
ohms
Multimeter set at ohms .200
Reading swapped both ways = 01.4
AC on .200
while cranking engine with fully charged battery but not fully running on idle ( it fires sometimes but not enough to run consistantly )
reading on both wires = average between 01.4 to 02.0
average is 02.0
results set at AC .750 same test = hv 006 both ways
when tested with negative multimeter to either wire and positive touching ground engine = 0
Battery ac .20 test while cranking shows a lower reading than the 12.40 before trying to start engine but sometimes shoots higher
I presume my stator or pick up is faulty but would this prevent bike from starting with a full battery ?
could there also be a cdi problem or rectifier or something ?

Those wires are not the ones you check for starting issues, unless you're investigating why the battery goes dead. The two wires you are checking are the lighting and charging wires. The black/red and blue/white wires (colors may vary) are the ones you want to check from the stator to see if it's able to provide a spark. Blue/white from the pickup should be in the ballpark of 0.5VAC cranking. Black/red should be somewhere near 60VAC.
The very first thing you should check is much simpler than these multimeter tests... Do you have spark?

Hi yes i get a spark when tested against the engine .. it tries to start while cranking at times when i open throttle slightly but not if i try to rev fully
I wondered if it was something to do with fuel but its the same with a brand new carb & when i tested it with propane gas into the air filter pipe

If it's got a good spark, then unless it's a timing issue the ignition system should be alright.
I think you posted on YouTube that you did a valve adjustment? If not, do one. Compression test is a good idea as well. You want to see at least 100psi, more like 150psi for a strong runner.

Propane gas into the airbox? Is that some kind of redneck Wannabe NoS kit? No offense, i just never saw someone test ignition/fire on a scooter that way. I know about the"pour gas into the spark plug hole" trick, but first time i see the someone use propane to do this test. Maybe i should go out more often.  |

I copied your video to set the valves .. today i will have a good look again and maybe do a short video to see if it helps.
I bought a compression tester on ebay but i dont think it has a fitting small enough for this spark plug type.
lol propane gas.. yes theres a fitting on the pipe that leads from the air filter to the carb. A mechanic told me to try it.

Thx for clarifying this for me. And by the way:  |

If you're gonna check the valves again, be very sure the timing marks on the flywheel and cam are lined up at TDC.

checked the valves again and seem ok I tested the pickup coil and there no resistance on the ohms setting I found this>> information << regarding my cdi , it says my dc cdi also needs 60v ac from the stator do you think this could be causing a weak spark or something ? Also now i have this new problem: when i connect the battery the ignition starts to crank without the key turned or kill switch even on. I took the switch apart and disconnected it but the bike still cranks on its own looks like its bypassing the switch any ideas ? |

Using propane in airbox snorkel to fire an engine is old school tech i been using for years. Safer then starting fluid. , good for finding vacume leaks too. |

Thanks I've ordered a 10mm compression fitting I didn't mind buying parts so far because when i find the fault i will be putting older ones back on and keeping newer for spares on future bikes i buy. Ive been buying cheap scooters to learn to fix and sell .. slowly getting there |

I had this issue when I got an old Yamati Strada to tinker with. I put a new system in and it worked fine. I didn't have the plug loop to put in at the time.
I didn't even know I had it until I took off the front plastics to replace the dash lens. There it was, box and siren. Must have been left on remote start and I had no remote. |
