Hi,i have a problem on my bike,between 3-5000 rpm the bike stutters/a slight misfire that makes a juddering sensation,the rev counter seems to falter while this happens,not apperant under accelaration,but what would be!I also have a intermitent non start problem,which i have found to be the wire on the neutral switch,if i wiggle it away we go.Are these two part of the same problem ,help ?????
