Ok then the ignition firing circuit is complete and correct. Do you have a nice hot looking blue spark? A weak yellow/orangish spark is not good. This is probably fuel/carb related? How long has it been since this machine ran?

Nice blue spark at the start going into like an orange color but good spark and it's been like 2 years since the bike has ran and when the bike is kicking over there is blue smoke coming out of the engine this tubey kinds thing lol  |

Then I'm betting you're going to get to take the carb apart and give it a good cleaning, you also are going to need to drain the gas tank and clean it out too. When I say carb wiring I don't mean the throttle cable I mean what is called the autochoke which will be two electrical wires, some carbs have this some don't and those that don't generally have a manual choke of some sort? here is a carb that shows the auto choke: img.auctiva.com/imgdata/4/7/8/9/5/1/webimg/89204208_o.jpg |

Is this a 4 stroke engine that runs just on gas or what you may call regular petrol or is this a 2 stroke engine that runs on fuel with 2 cycle oil in the gas that you mix in? |

This is my carby and the the thick wire is going to thumb throttle so i guess it is manual ? And just a question if im wrong or not... if i spray start ya bastard down the spark plug hole it should kick over correct ? And yes JR it is a 4 stroke   |

I don't know what this is? Would this be like a starter fluid say what we call here ether? Also it doesn't even look like you have the carb hooked up to a fuel line from the gas tank? Again is this a 4 stroke engine that runs on gas alone or is it a 2 stroke that runs on mixed gas with 2 cycle oil in it?
Again if this engine has set for two years you're probably going to have to do some serious carb and fuel tank cleaning. Sometimes when engines set a long time the rings can stick and the compression will be very low and it'll just not run?
A simple test is to pull the spark plug, put your thumb over the hole and turn the engine over. If you can't hold your thumb over the hole due to it blowing off then you have good compression.

Also a weak battery can make the engine turn over more slowly and hurt the quality of the spark. you need to check the battery and make sure it has a good hot charge with a meter and it needs 12.5 Vdc or better.
Missed the answer on it's a 4 stroke and I would put some good fresh gas in the spark plug hole.

Excellent compression JR I'll charge the battery and put the gasoline tank back on and is there a video or something on cleaning the carby ? And when you say put some fresh gas into spark hole just squirt some in there ?
Also if I have to buy a new carby what would you suggest ?

Ok JR I have really good compression I did the test and thumb kept blowing off , I cleaned the carby jets etc float is good all seems good there , I tried to start it with some good gas down the spark plug hole still no good battery was dying lol so my battery is on charge now see what happens with a good battery after charge. All the wiring is hooked up correctly what else could I do ? Could it be the timing I don't know just throwing some thoughts maybe carby buildup somewhere ?
Can I just also clarify this ok ... The Black/White wire coming from the handlebar kill switch assembly going through the male/female plug connecting to Black/White which then is going into a spIice . From that splice I have 1 Black/White wire going directly to the CDI ok and also from that splice I have 1 Black/White wire going tthrough male/female plug then connecting up to the Black/White wire coming from the key switch

And when you say put some fresh gas into spark hole just squirt some in there ? Also if I have to buy a new carby what would you suggest ? Yes just a little squirt of gas right in the spark plug hole, put too much and you'll make the spark plug too wet or do what we call flood it. Here is some videos on how to clean your carb, different machine, principal the same. It's good to have a can of carb cleaner and some high compression air when cleaning a carb, pay close attention to all the jets and such being open and clean. A machine that sets up a long time will have deposits in the carb and tank and sometimes cleaning is tough. I'm not a ATV man so on buying a carb you'll have to work on that one yourself, measure everything and look on ATV sales sites, Ebay and you might look for a ATV forum to get help too? |

Yes you are correct on the BLACK/WHIE wiring, splice the BLACK/WHITE from handlebar switch assembly to the BLACK/WHITE on the key switch and then run it to the BLACK/WHITE on the CDI. Also we can test the handlebar kill or engine run or not run switch. Pull the sparkplug and turn the engine over to observe your spark. Then put the switch to the engine not run or kill position and again turn the engine over. You should not have a spark at all on the spark plug with the switch in the engine off position. |

Still no luck JR new fuel etc checked kill switch test with spark plug all fine there now I don't know what ealse ?
Does the solid green wire coming from engine need to be grounded ? I don't know lol just thinking
Have fully charged battery good spark good compression fuel running through the carby
Also I put my multimeter on the battery when trying to start it and it shows 11.48v but that is after attempts trying to start it . I also took the exhaust off where it connects near the spark plug and really dirty black I guess you could call it carbon build up in there maybe also makes a popping noise with exhaust off and trying to start it [Maybe no spark While in the spark plug hole because it maybe firing at the wrong time

No the green wire from the engine pigtail goes to the R/R along with the other two yellow wires. It's common for a engine to back fire with the exhaust removed.
The wiring is all right, if you did the kill switch test and it was ok then that's the final conformation that the wiring is correct.
When a engine sets up for as long as 2 years to revive it sometimes is painful. Have you checked the muffler to make sure it is clear of possible insect infestation or even rodents? Where I live we have this wasp called a dirt dobber, they make nests out of mud and believe me they love places like a open muffler and build a nest, can plug up things quickly, rodents can do the same thing.
It's common for a battery do drop to that kind of reading when cranking on it for a spell, just keep it charged up. Other possible things with a long time setting engine is a sticking valve.
On your spark I'll ask again, is it a good looking blue spark? if it's orangish/yellowish. it's possible you have a weak coil or even a poor CDI or both?
I can only give you suggestions now, the wiring is correct.

Yes when battery is fully charged it does have a good blue spark and exhaust is clear
