need to holla at some royal purple along with z max for a few treatments. U can feel the differentce. Its not just in my head. I understand there is no pour in mechanic, but it helped. It runs so smooth and burns little to no oil. I used to see the "honda Puff" every time i got on it, Now its all gone. Just sayin, i believe in Royal purple and Z Max.
But yes as stated above. Burning oil... If ur burning it, then it would be seeping through the valve seats or coming past the comp rings. Pull the head off, get a valve job, pull the pistone out, have the head shaved and block, if needed and hone the block real good and throw new correct size ans spec rings in it. then ur good to go. Depending on the mileage of engine, Just rebuile the entire thing... Trust me, ITS WORTH IT... I built mine and its an amazing fun little reliable engine
