Okay so I'm a firm believer in using the search function and looking around before posting but my phone won't let me! With that being said..

I took my bike for a ride today and noticed some smoke coming from the exhaust. Before there was little smoke when I would get on it but I was told that was normal "blow by" as the rings were possibly going.. now I think she was smoking while idling but I'm guessing because it was warm but now I'm concerned. I definitely don't want to blow up another engine or ruin my internals. Any help would be greatly appreciated. Im guessing I'm going to have to open up my engine now and do some work and this will be a first for me. If I'm looking at new rings etc sizes and whatnot are going to be unknown to me, shed some light here for me fellas I've come across great help on this site and I appreciate every bit.

Also, on a side note.. I notice some oil leakage from my oil filter cover on the bottom, possibly just the seal on there leaking?

Thanks ahead of time guys,
Chris.

I would say the seal on the filter cover. :iagree:

As for swapping out the piston, and rings.. It's not that tuff.

Pull you timing chain cover, and rotate the motor till the timing marks line up.. Pull the timing chain tensioner, and remove the chain. (You may need to remove the cam bolt? just let the chain drop down)

Pull your head pipe, carb, and anything else attached to the topend..

Then undo the 4 nuts on the top of the head, and pull it apart!!

Take your jug in, and get it honed (or bored if it looks like it has some gouges in it?).
Replacing your piston is easy.
2 clips, and tap the pin out.. Put your rings on the piston, and reverse the order putting it back together.

Anybody can do it.. :tup:
 
wellif it is smoking while it was running that could be your rings, if it smokse upon startup then that is your valve seals and yeah that oil could be coming from your oil filter cover. If you open up the top end you'd be better off puttin new piston and rings and bore possibly but most people can just hone the cylinder and then throw a new piston and rings in it.
 
Could you guys point me in the right direction of the correct size rings and piston to buy? :D
 
yep yep take jug to shop and have them measure the bore of the sleeve then you will know what size piston to get depending on if it needs to be bored out or just honed

Exactly. :tup:

The next person that tells me that buying the piston first is the way to go, from a machining stand point...
OMG!!
I'm gonna loose my mind!!!!

I can't remember who said it on here?
But I read it twice on E2S..

Now I have to think why??
Why would you wanna buy a piston, and have no idea what size the bore is?
Especially when your green at this stuff?

Get the jug work/head work done.. Then buy the slug you want!!

Thats my $.02

Buy'n a stock piston 4 a engine you know nothing about is tarded!!
Your wasting money on a hunch. :argh:

Measure, price, then buy.. And know what your after as an end result.
 
well I know when my buddy brought his jug in to get measured they told him he needed to go .040 over stockand to go buy a .040 over piston and when he gets the piston to bring it with the jug and they would match the jug to the new piston
.
but yeah say you buy a .040 over piston and rings to redo the top end and you get the jug off and it's already bored to that(assuming you don't know if anything has been done to it before you, previous owner) now you got a piston that will be too small for the jug after boring it more or something like that right?

That was my point..
Thanx Hauler. :iagree:
 
You could always wrap duct-tape around the piston and make it fit. Bahaha!!! ( seriously, engine novices, this won't work. It was a JOKE!!!!):haha:
 
Could just drain oil and fill with "Stop Smoke" ????
What a tangent we got onto.
What does your oil look like?
Black and thin? Diluted with gasoline? ( From a stuck carb float)?
Maybe change and use 20W-50 Petroleum based oil to get you through the season??
If not yep overhaul.
My 0.02$

I have to agree with that. ^^

If you don't wanna pull it apart right now, and would rather ride it till winter hits.. You could put a bit of that engine restore in it, and some heavier weight oil. That'll keep it going a bit longer.
 
Haha appreciate the change fellas. Definitely some good advice here. I'll pull the top end apart and see what we got goin on in there. Oil looked fine last time I changed it so I'm not too sure but I'll post updates when I findout more. Maybe electrical should do the trick haha. But anyways, I'm just going to do the work its not worth blowing the engine up I've a top end rebuild. So in other words get the whole top end rebuild kit with the size bore they tell me at the shop? Any brand better then the others?
