hi everyone new to the site and new to pwc. my brother inlaw bought a couple yamahas last week and we are having problems with the 1200 the 800xl runs great we put new batteries new spark plugs new oil new fuel filters on both when we were done the 800 started right up and sound great and rode great at the lake. but the 1200 has a really rough idle and excessive smoke out the rear. like i said at the begiining of post we are new to jet skies so any info u could pass along would be great. or if u need more info on them let me know
