O I didn't know it was a difference... In my scoot, the turn signals can work without the rectifier.

I cleaned the carb before but I forgot when. wouldnt hurt to do again. Shouldn't be any air leaks but I do need to zip tie the rest of the vacuum hose. I don't really know if the valves are leaking. I'm going to liquid test them when I take the head off to fix the exhaust studs. Does scrappy dogg scoots sell stainless steel exhaust studs? Im not sure bro,,but he might. Yeah the liquid test works great! Also I got a cheap compression tester from HF that works awesome,,if you find low compression you can also use the quick disconnect on a homemade leak down tester I made from an old air regulator,black pipe,JB weld,drill,teflon tape,and a couple connectors. There are a few videos on youtube how to make it. By listening to where the air is hissing from will pin point your leak,,hissing from carb air filter inlet would be intake valve,from exhaust pipe,would be exhaust valve,from oil filler hole would be bad rings/piston/bore issue...also listen or spray soapy water around head gasket to make sure its not leaking. Very cool diagnostic tool,,a must have IMO. Piston must be at TDC for testing. |

So ur scoot uses a DC cdi ,and u used an ac regulator ? From what I always understood the regulator for a DC setup is different from an ad setup. That could be the main problem . that along with a good carb tuning u may be OK.

Yeah I'm a little confused too. The regulator is a 4-pin harness in the front of my scoot. The blue AC CDI doesnt work with my scoot though. Its just make a barely noticeable spark. Stock CDI looks out of this world but it works. Its big like a DC CDI, but the cdi harness looks ac. Just a weird electrical system. When it was crank, I accidentally hit the loose battery cables and the scoot turned off. I don't know...

Im going to try what this guy did to know if my scoot is ac or dc and to see if my elctric system is good. geh3333 |

Alley has a simple test
Your CDI has a 4-pin connector and a 2-pin connector. The 2-pin is the key.
If, with your scooter "on" but not running, you see +12VDC in the 2-pin connector you have a DC scooter. If not nd you see ac voltage once the thing is running, you have an ac scooter.
Mine also failed all the usual tests, but Alley's made it crystal clear and without any uncertainty.

Yup and on the opposite wire(usually a red/blk)on the 2 pin comes from the stator if AC you will see 70-  AC volts under cranking depending on how fast she cranks over... Just wanted to add some values too look for.. |

Thanks, wonder why alley haven't commented yet? Anyway my cylinder came with 14g cylinder rollers. Is it really noticeably different from stock rollers?

I think mine came with 13g rollers stock..I love my 13g sliders man..I still want to try 14g rollers one of these days,,but am so pleased with my sliders..seems like they shift into higher gearing faster,,great for me cause I like to cruise 40-50 MPH under 7K RPM.

What is this empty connector?  Looks like it could be to the auto choke on the carb. Is this connector empty?  |

The auto choke is already hooked up. Thats a random connection I found Iand I have no idea where neither goes. They fit into each other but the get really hot and blow the fuse. I know both are pulling voltage from somewhere. I need to trace all my wires one day.

Im a computer enthusiasts and was wondering could thermal paste be used as lapping coumpound... Help

I wouldn't use thermal paste,,it needs to be a bit grittier,,if in a pinch I might try toothpaste(the white kind)but your better off just spending $6 and getting the Permatex.

Alright so I tested the cdi and it looks to be ac. My battery was about dead so when I put the multimeter on acv and tried to crank it, it only read about 4ac volts per round. Read 0 dc volts when key was turnt. I put the negative point on the black/ground of the 2 pins and put the positive on the red/black side of the 2 pin cdi connection to the scoot.
Problbly need a new stator because I put the blue ac cdi on and the plug had a small spark. When I put the weird stock cdi on, it had a regular spark though.
Its very weird. Everything points to it being a ac scoot except the blue cdi not working. But it lights green when I try to crank.
