Yesterday I bought a yzf426. I took a chance and couldn't get it started but. Most everything checked out ok on the bike but after getting home and changing the plug it won't fire up. I know there is a procedure to Wich I have followed with no results. I pulled the plug again and it is pretty wet no discoloration just clean gas. I grounded the plug to see if I got spark and I do it just seems weak to me. Could weak spark make it not fire up?
