Need More Help With My 250R!!!

[PYF]

Hi again all 2-strokers. Thanks for all your help in my previous topic..To make it short, I had a problem with my quad cutting and I though it was a carb problem but after trying many things, I figured out my jetting was right on and that I would need to go farther in the engine... Then I thought:''If it's not carburetion, it must be ignition''...So I Opened my flywheel cover to discover with horror that there was some water in it !... Everything in there is rusty...I started by removing all the rust on the pulse generator, since it was covered in it...No luck, it's still cutting...


THere is also some rust on the flywheel and I don't know the state of the stator since I don't have a puller to remove the flywheel...Something else too, when I move the flywheel up and down, there seems to be some free play. Can't tell if it's the flywheel on the crankshaft or the crankshaft moving though...Is it normal or does it means my main seal/bearings is shot ?

So here are my idea of what could be damaged...let me know what you think

Pulse Generator
Stator
Flywheel (Unlikely AFAIK)
Coil
Bad/Damaged wire in the harness (Unlikely too, checked most of them)
CDI BOX


I have my service manual and tried to check the resistance of the coil but looks like my multimeter sucks (Or I just don't know how it works, go figure...)


I have another problem though (Which really piss me off too)...The quad is drinking awful amount of coolant!...It can drink a whole radiator in a day...

I got the radiator pressure checked, and there were no leak. Head gasket looks good, every cylinder head bolts looks like to be torqued correctly. All the hoses are allright. Just changed the water pump mechanical seal so that shouldn't be the problem. The only place it was leaking a little was from the refill tank hose but I fixed it tonight.
Another strange thing with this too....The radiator will be empty but the refill tank will still be full,...why isn't the tank refilling the rad ?



Thanks again a lot for your time guys/gals,

Small Update...

Checked the resistance of all the coils (Don't remember the name) and they were all in the given range excepting the ignition coil which is supposed to be 0.1-0.3 ohm and was 0.05...

Both secondary resistance were not in range either...


Could it be my culprit (Looks like it is but I still ask since I know nearly nothing in electric)

Grab your flywheel and pull up and down with force and if there is any movement at all then main bearing/seals replacement is highly recommended.

I can feel a little LITTLE little free play when I do it...

No vibration when the engine is running though...

Hmm small update:

Just came back from riding...pushing the quad

I was rolling at a slow rpm going somewhere when it just start bogging like it was short on gas...Would idle but no go over 1/8 throttle without stalling. Checked the fuel valve, fuel tank and spark plug...plug was nice, but the spark was yellow (not blue) and somehow weak. Changed the plug for a new one, same thing.... The quad don't start anymore now. I think my coil finally quitted me...Hope it's that...Any inputs welcome

Thanks

Ok solved the problem about the bogging, the needle clip kinda exploded in the carb so the needle was stuck in the main jet at any RPM lol

Not solving the spark problem though...


Something else strange about my rad, the refill tank fill itself from the rad lol...It should be the opposite, the refill tank is supposed to fill the rad :S What could cause that?

if your rad is not holdin water the frist thing i would cheak is leak down u said that is good then i would go to the case and see if u have a milk white fuild in your trany that from cooleat getin into your trany case from your wet seal goin bad. and cheak your pulsor on the left side of your shirter the cheak ohms sould be MORE then .7 ohms if not its bad
