Yfm350fw

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!!

Have you tried rolling it to start?

Hi, the cylinderfot gasket on my Big Bear 350 -92 (4-Stroke, SOHC) is leaking some oil and i was woundering, is it difficult to change it yourself? Also, when the engien runs on idle i can feel like small "hits" (spec. when its cold) What might it be? And last, when i put full throttle, from idle, the engien dies. You have to give som gas first, then its ok to give full. Is this normal? Thanks for any help!
