problem with misfire.

at first it seemed like wheel out of balance,at 110 it shakes itself to bits,so new tyre & balance ect,then i found if i nail thottle in 4th 5th & 6th it misfires,dont do it in lower gears,when it misses it shakes like it does at 110. just wondered if anyone had this? ill start looking for kinked fuel lines & new plugs before i start changing coils & carbs. any ideas

cheers.
bob.

Have you looked at the head bearings Bob for the shaking??

done all that m8,head & wheel bearings,i think its with allways having 4 pot bikes that just lack power when missing,it took a while to realize that when twin misfires it shakes like a bastid

. just had carbs of & to bits,not a speck in jets or float bowls

put back together & fired up no probs,ill give it a run tomorrow & go from there,plugs next then coils
