the video says it all.
if you guys need any better pics of a specific area please let me know soon, as i go to work in about 2 hours and will not be able to post any pics until later tonight.
could it just have been that my rings rings spun out of alignment and i was getting oil shot into the combustion chamber?
I will realign my rings before i put it back in dont worry about that btw.

If you soft seized there would be scuffs and scratches on your piston and cylinder. I never saw a good look at the cylinder but that piston looks fine. There is a lot of carbon in you combustion area. A you running really rich?? Do the valves properly seat? I would check that and put it back together and run that puppy...

I agree, but is the mark on the piston really a dent or scuff? Possible the intake valvee hit it? when you put the piston in, did you make sure the I was on top?I dont think It's possible for the intake valve to hit the piston, as the piston is on the way down when it opens.(assuming timing is correct.) Maybe a tiny peice of junk found its way to the valve seat? IMO, clean it up and try again.

I would check that and put it back together and run that puppy... ya i tried earlier to get pics of the cylinder but none would turn out well enough to actually inspect them. no all that carbon is from when i was messing with my f/a making it run really rich. i dont know how to check to see if the valves seated properly. and thanks jersey. |

Easiest way to check is with you eyes. Just look and see if you see a gap. Push the valve out a bit and check for any debris caught in there... If you can't feel any irregularities in your cylinder there likely aren't any...

ok so i just checked out the valve everything looks fine as far as i can tell no light coming through when its closed and when i open it i dont see any debris. unfortunately my base gasket got ripped taking it off so i still have to wait awhile before i can put her back together.
but just so im clear about this because i cant really find any videos or readings about this, the gaskets go.
no gasket on the valve cover (except the vent thing)
the metal head gasket on the base of the valve head top of cylinder
and base gasket between the bottum of the cylinder and the top of the engine case
if im wrong with this could that have been a reason for the oil getting into the combustion chamber?

[replyingto=newbscootdude]newbscootdude[/replyingto]From what I can see, Everything looks a-ok. and you are right about the gaskets, you can use rtv silicone on the valve cover if you wish. I cant see any reason why you got oil in the cylinder. Did you have the bike on it's side, or tip it in an abnormal direction? I would just assemble it again, and turn it by hand several times with the plug out to see if it binds. If not, run it.

If not, run it. no the bike didnt tip i always keep it on the center stand, did you see the i wrote that my base gasket is ripped? its not bad just a little piece out of the corner on the upper left hand side that stayed on the engine case. would it be unwise to reassemble it with that rip in the base gasket? |
