i used a harbor freight torque wrench and i set everything to 10lbs more, to check if a head is warped you measure the distance between the corners of the bolt holes crossing and they should be the same, measure upper left to lower right and upper right to lower left if the distance is off, it COULD be warped, its hard to tell with smaller heads

For the ruckus crowd (myself) when we swap we have to use 11 poles in order for our batterys to remain at a full charge due to our headlights and such, my gy6 is wired with all my accessorys running dc and all lighting running dc the 11 pole stator's 3 yellow wires all charge the battery, thats what youd probably want to do

well i let mine sit overnight but thats because it had 4 carbs and all the cylinders were flooded, in the case of the scooter, if you can get ahold of some starting fluid, after having had it sit for a few hours spray some starter fluid into the intake and give it a bit of cranking with some throttle snapping (on the stand of course) it may take 5 minutes or so but it will eventually start up, if you DO have the tools do remove the spark plug, remove it, drain the fuel bowl and crank the motor over for a minute or 2 so it shoots any excess fuel out of the cylinder, then put the plug back in and prime the fuel bowl and it should fire right up, make sure the plug is dry as well, wipe it off, blow it out etc

happened to a bike of mine, flooded it, let it sit for a good bit of time, and try starting it on the stand giving it some throttle here and there, if its flooded eventually it will start up

just replaced the oil seal and the stator on the bike starts and idles fine but wont rev over 3k rpms +/- a few hundred rpms, its almost like its hitting a rev limiter? could the carb cause the type of situation

well sometimes when going bigbore you up the compression and the battery may not have enough cca's to continue to have enough to juice it and start it up over time the battery looses is oomph

Check the red/black voltage wire from the stator to make sure its putting out 50-100ACv then test the coil + lead to make sure its getting the atleast 19ACv, leaking valve shouldnt stop it from starting, have you pulled the plug and plugged it into the boot and attempted to start to check that the plug is firing? these coils and cdi's are not built very well, i ordered 2 new cdi's and both didnt work 2! the third one did, so id definitely check for voltage, also make sure any visible grounds are tight, i cant imagine a coil blowing apart..

its probably shorting, or if its your line from the rectifier regulator it may be going bad

because your not actually getting enough volts at the plug to cause it to spark, or spark strongly, OR, its not grounded enough to show it, the engine acts as a ground for the plug so it sparks more inside of the cylinder head than while you have it exposed

What wires did you run a multimeter to on the stator, right off the back sounds like you just need a new stator or a new regulator rectifier

thats what im so confused about, other people with the same long case gy6 scooter engine have used 842's and say they work.. what would be the effecting factor, my guess would be that just on low load it would be a little loose because on my variator face i still have a little ways to go up and it seems the belt might be too short, and on scrappydogscooters it says 842 is a replacement for 835's, :/ just unsure of what i should order.. maybe ill order them all and get a definitive answer

so my stock belt is an 821-20-30 but it appears that most common is 842 and i hear thats an upgrade however that sounds like a really big jump, can any one verify this works or should i get the 835?

What size stator do you have? i can tell you that i had a voltage drain greater than charge rate on my 8 pole stator with my first swapped ruckus while powering 2 35watt h4's Most people i have read either swap to an 11 pole and run HID's or they get 18 watt bulbs

Unplug your coil and check it's resistance. The primary winding. ( across the spade terminals) should be 0.1 to 1.0 ohm. The secondary winding ( green - spade terminal to sparkplug lead) with cap should be 7K to 9K ohms. without cap should be 3K to 4K ohms. if the coil ohms out ok, I would try another CDI. ( then replace the coil also if that didn't fix it. ) If the Hi-voltage capacitor in the CDI is blown and shorted, if would cause the voltage measurements you're getting. The standard resistance of the stator winding for the CDI power (black/red to green lead) is 500 to 600 ohms. The standard resistance if the timing pickup coil ( blue/yellow to green lead) is 80 to 160 ohms. Your wire colors might be different. You were right about the hi voltage capacitor i think earlier today i was thinking, "It doesnt make sense, but what the , ill try another new cdi (the one i have is "new")" BAM fired right up, AMAZING, how it is that you can get such a high voltage output on the coil and yet.. have it not fire? i was completely baffled for days.. I think your statement about the Capacitor should be put into troubleshooting spark FAQ's because that was listed no where, i was getting all the correct measurements and still no spark Thanks alot!
