    main problem........ its a YAMAHA duh.... second and the real problem its the rings... if it smokes when you leave off the gas then its valve seals if it smokes when you give it gas then its deflently the piston rings.... put new rings in it before you hurt the bore

    nope not in somthin like that it wont help... rings are only 30 bucks at most thats the best way to go... your guna need a head gasket base gasket and vavle cover gasket also... get it done before it gets to sloppy
