ive had a 160 manifold sitting around for a while so today i decided to fit it to my 120, problem is that now there is a horrible vibration at around 4000 but goes away if below or above those revs. wen i fitted the exhaust i double checked all the nuts and bolts so i dont think its these.

any ideas any1??????

cheers
