NEED HELP, CYCLONE head, bent exhaust valves??
alright this is what happened i just bought a 92 talon 5 speed, and replaced the head with a new cyclone head, well when i fired it up it seemed as the timing was off, so we set it right but now at normal idle something is vibrating, i htink i bent 2 exhaust valves or the bearings something happened but at normal idle it vibrates to where the timing belt looks like its about to bounce off, but at 2,5K rpm, it sounds smooth as can be it runs like a champ though just at low idle it vibrates and makes a vibrateing noise NOT A PINGING or KNOCKING just vibrating, does any one know what it could be and what i can do to check???

yeah i know its just the air manifold is open larger then stock, i know, i think i figured it out though i think i might have a bad tentioner or whatever , but yeah i check the valves and nothing is vibrating but the tentioner is moving its not supposed to so im going to get a new one and put it on hopefully thats it... then ill be ready to switch everyhting off my black 93 on to this one...fingers crossed....thanks for the comments also appreciate it...

I would have to got with Ninety7GSX, did you check the balance shafts? It's pretty simple to get the rear balance shaft out of phase and it will cause the entire motor to wobble like a champ. My new motor will be missing the balance shafts
