163FML oil in flywheel cover...

Superdust · 07-15-2010, 10:25 AM

Hi

I have a Kinroad ATV with a 163FML 200cc type engine.

Lately I have been having some start trouble.
Then it would not start at all.
There was no spark from the plug.

I changed the plug for a new NGK.
Still nothing.
Then I changed the CDI.
Still nothing.
Changed the coil, same thing, nothing.

Then I decided to check the magneto.
When opening the cover over the flywheel, a lot of oil came out.
Is there suppose to be oil here?

Guess some oil seal is broken.

But how do I remove the flywheel to get to the seals?
I see that there is a bolt holding it, but do I need some special tool to gold the flywheel still while loosening the bolt?

Any thoughts on this is welcome

I'd check for loose or broken wires.

Good tip.

Do you know if there is supposed to be a lot of oil in there?
None of the other bikes I have had in the past had had oil in the flywheel housing...

Yeah there should be no oil in there, i haven't had to pull a flywheel yet on my dirt toys, but on my snowmobile i used to use an impact to remove the bolt, there was some tapped holes in the flywheel, i used a homemade puller which consisted of a pc of flatbar with 2 holes to thread bolts into the flywheel holes and then welded a nut on the backside of the hole i drilled in the center, then tightened the center bolt to pop off the flywheel. If you have a pic of your flywheel i can show you what i mean.

I must also ask if you are the only owners of this quad, is it possible that someone actually put oil in there without you knowing?

Thank you, that sorts it out, an oil seal is broken :(
I`m the only owner, no oil has been put in there.

Hope it will not be a to hard job to change the seals.

If anybody else got one of this China bikes with the 200cc 163FML engine, you can have some use of this service manual, as the engine is pretty similar.
PS I did not upload it, just found it.

If your engine is a Honda clone (and I believe it is), then yes, there is supposed to be oil around the flywheel. I'm building an XR200R for my son right now, and I can confirm that the flywheel is exposed to oil.

I know that is counter-intuitive, especially since the magneto generates voltage. I know that my buddy's WR250F is the same, as was his YZ250F. Conversely, two old Suzukis I had used a dry flywheel, as did my son's Honda clone pit bike. the difference is that the pit bike used a horizontal engine vs. your vertical. Different oiling system.

I remove the flywheel with a flywheel puller that I bought on eBay for around $8.00. So far, it has worked on Honda XR engines, Honda GY6 engines, and Honda horizontal engines.

X2 on checking the wires from the stator.

There is supposed to be oil in there, with the electrics in there?
Really strange...

Well, then I guess I have to find another reason why there is no spark.
Will be checking all the wires with my multimeter.

Can anybody confirm that there is suppose to be oil in there?

Yes check all wires.

Wires at the coil, at the cdi, along the routing. For breaks, tears, or even pulled out of their white plastic connector pieces. Can be a bitch, because they will pull out, but not all the way, making it hard to find.

I'd guess your no spark issue is one broken wire somewhere amongst the mess.

I can't confirm or deny the oil by the flywheel, you have two smart people offering you differing opinions, but if W&G has seen it in various makes of motorcycles like he mentioned you're probably fine.

I can't say for sure if there is or isn't, but it is very strange to have oil there, as there's no need for it as a spinning flywheel and the ignition coil / lighting coil don't need to be lubed, strange :? :?

I haven't bothered to figure out why oil circulates within the stator housing, but there is an o-ring seal on the cover for that reason. Bikes with dry stators don't use an o-ring.
