ok, this isnt for a zxr400 but my zx7r. i thought id ask here as its been the best place for help over the years.

ok,im thinking its probably the chain but when sat riding with the throttle just open, cruising along, 30mph or 70mph etc i hear a flapping,tapping noise and can feel a thumping through my foot pegs. and it seems to alternate tween left and right peg as im moving. it doesnt do it at standstill.

thus i think its the chain but its tensioned correctly and its really bugging me.

any ideas guys.

Never had that on mine when i had it. Can only imagine its either the wheel or swingarm bearing myself. The flapping noise may just be the chain anyway, does the knocking sound coincide with the flapping sound?

yea it does. i thought it may be a loose sidestand so i repaired that as it was loose, if i accelerate it goes away then as i get to cruise it starts knocking again. i checked the front sprocket and thats tight, i had new tyres 3 weeks ago and the bearings were fine when i checked them as i did the wheels meself.

ill re-adjust the chain later and see what happens.would be nice to see the chain as im moving but its a bit hard lol.

could well be the chain if it has some tight spots? check the chain in several places and i don't mean london, bristol & scotland.
