Hi, i have a yamaha atv. Its a 4-stroke, 1-cyl, ac, 348cc SOCH. I was woundering; 1. What do you have to remove, generally, to replace a cylinderfot gasket? Is it complicated? 2. When the engieen is cold (just after start), i can feel like small "hits". Its nothing you hear, just feel (in you as ). Is it something to be worried about? Could it be knocking?
Thanks for any help!!
