These images are from my 4th rebuild on my Gas Gas 300. I reused original Base and Head O rings all four rebuilds. The Oil I used was full synthetic Penzoil TCW mixed 40 to 1. Could not beleive the Good results of the oil. I recently won $500 worth of Amsoil, I am hoping to have the same results or better. Power valves had a low amount of carbon, the piston and cylinder looked like new. The Penzoil TCW was only $20 dollars a gallon opposed to $40 a gallon of Amsoil.

Thats awsome but this should be posted in General or 2 stroke section.
 
Looks like you were getting some blowby past the inner oring and if you head is that clean with zero soot your prob jetted pig rich.
 
Moved the thread to the 2-stroke section.

Why reuse old o-rings and gaskets? Bad practice. If your going through the trouble of doing a top end use new parts.

Your photos are of the top of a new piston. Show the old one. Amsoil Dominator is great oil, been using it for years.
 
Ohh in the case this is just a new pistion thats horrible. I have 300+ hours on my stock piston. It needs a new one for next season but still. You should never re-use gaskets or O-rings like said before.

Amsoil dominator is the best money can buy. Works like it should.
 
Thank you for moving the thread

Yes this is the honest to God photos from my piston and head with 4000 miles on it.That is why I took the photos. I knew no one would believe me.pennzoil marine tc-w3 100% synthetic -biodegradable ashless oil.It is not recommended nor do I recomend it for your bike.But the photos are the results from that oil.My jetting at 600- 1000 ft is 40 pilot n1eg 2clip 178 main ,2004 300 GASGAS bike has never seen pemium gas . When I use to race I ran the "A class "for about 10years so I am not too slow or easy on the bike.I do not recomend reusing old gaskets. I am showing you my results.I am very cheap but growing up that way allowed me to have a full retirement at age 50. that year ,I rode my gasgas 265 days consecutive rain -sun and 16" of snow last day Jan 16 right through deer season no shots hit me. Just to set a record here for the boys to try and beat .This is in the Upper Peninsula Marquette Michigan Where we hold a National enduro most years
 
Well I don't see why you would post false, especially since no one else initiated this post but I am skeptical also. Doing this stuff for a living I have seen propane engines similar but can't imagine how lean that would have to be to stay that clean being 2 stroke. But if true, I would say you are doing something right:cool:
 
Yeah. Its called hogwash, just dab a little on your, : scam wow: and voila!

The last time I had a piston look that clean when I pulled the head it was because I had a blown head gasket and was sucking in coolant and burning it.
 
from Hydrodog...
sucking in coolant and burning it.

I could believe that, coolant will definately clean the piston and head off. Might explain what others say look like blowby in the pics though I don't find the pictures clear enough to make any assumptions.
 
Thank you Hydro Dog and Jostby for not jumping to conclusion's. I think you hit it right on the head "sucking in coolant" I don't know why I though oil. I must be getting dumber in my old age.I seen this before with leaking head gasket on cars.I also worked on propane engines and was always amazed how clean they were.I remember reading how the Germans injected water vapor to their manifold on their airplanes to help atomize fuel air because of their low octane fuel.Repairmen often commented how clean the pistons and valve-train were.Thank you Lance
 
If it were'nt for your dogged insistence re; discovery of lubrication nirvana and the merrits of being cheap , the rest of us are ignorant to your enlightened ways this thread would have never come this far, you may want to consider yourself fortunet that you have been pointed in the right direction by the good members of this forum before your engine or credibility suffer anymore damage..B.T.W. water injection or MW-50 as it was known, M for meth ,50 for 50% solution to keep the water from freezing at high elevations was used as an anti detonent/ combustion cooling medium in high output force fed aviation engines running boost pressure up to 39 pounds for enhanced high altiude perf and 2000+ hp outputs.

aardouzie I'm glad you posted this because since this threads o.p. is pretty much dead and its also pretty slow on the forum, so dear members please indulge me on this topic of being nice. Nice is for children and old woman!I contend that 99% of the problems we in the western world face today is because of this propensity we have been schooled in and adopted to be a bunch of sit on your hands wimpy nice guys and trust in government, big biz and political lesbianism to do the right thing, in short a bunch of castrated sheep!
Now some of you may question, what does this have anything to do within the context of a riders forum, well i.m.o. it comes down to this. Was Washington nice when he crossed the Potomic? how about that navy captain the gave the order to dispatch with those Somalie hijackers, Boston tea pary another one , the list goes on and on but we all get the point. When did arguement , vigorous discussion and calling it like it is and doing the right thing become a crime? Sorry I dont buy into the Peter Pan hippy b.s. that is being passed of as decorum or good maners.I'm not suggesting the we name call or use foul language , that would be poor form.Please remember that democracy is an obligation not a privilidge bought and paid for in blood that requires constent tending and any real man that gets dressed down is going to suck it up and come back tougher and smarter to offer something more to the world of today and this message STARTS AT HOME then our community and our country. All you every kid a winner liberal hippy the government will do it for us assclowns with no stomache for reality can smoke a fat one and teleport themselves back into the dark ages for a reality check.Over the top for this forum?
