Doubts with Yamaha Tzr 3ma ....

You are sure that the entrance of water into the engine is through those hoses of the carburetor ... I tell you why those hoses are fulfilled in the carburetor .... What you could temporarily try is to put a plug in the hoses so that water does not pass and check ... if it were wherever I would touch you would change the whole piece since it would be a bad idea to remove those pipes at all. also check if the head of the head is not damaged since water could also pass through there.
You need a tel test a pressure regulator to compress the refrigeration system

Look a companion I do not have much experience in funbike motorcycles or high cylinder but I think the problem is because that cylinder is arriving oil and this burning it for this reason the white smoke I would recommend that you review the cylinder again it may be that the rings are faced. Or you have to change the shutter or valve stamps it can also be that the packaging failed you and finally and I beg that it is not if it is badly rectified because if it were water that reaches the cylinder the engine the engine would go out I think I hope my opinion serves you ....... rene

Haaammmm I thank you for your Hamm subjects One more fact that does not mention the Ke Umea Muxo cylinder, when I put my hand behind I feel the comprehensive is not the best comparison of the other cylinder ... It can be that bad piston ????????? Thanks in advance, another you see ...

Fran, the white smoke in water present in the combustion, this has regularly threatens a failure in the button of the butt, in your case with independent cylinder heads is only because of the piston you mention, the lack of Fuersa in the exhaust tells you that the compression of that cylinder is low and this is for the same reason the packaging, now it is difficult for the water to get through the cooling conduits of the cooling. There is so much the precion that exists in that system as to try a cracks of mesclar water and fuel, and if for any reason this happens a good welder or ass is capable of solder and repair, but your problem is the packaging, if you want a real test that srtifies this problem you should only measure the compression of the cylinders and now, you can also check the oil in search of Emulcion. High power motorcycles is not very noticeable. Czech this and let us know to help you.
