Tawang Bang Bang

FINALLY got my Viking ready to roll. I start it up put it into reverse and give it some gas and Tawang-Bang-Bang comes from behind me in the motor area. As I increase RPM is quits, and as soon as I decelerate, again Tawang-Bang-Bang. My first thought is the dang vibration dampener is hitting the heat shield where I had to cut it out. I take a look, and behold, I did not tighten down the heat shield bolts (4 of them). I tighten up my mistake and am confident that my Tawang will be gone. I start up the unit and put it into gear, accelerate a little and Tawang-Bang-Bang still there. THEN, I remember a like problem that BadM0nkey had with his just installed JBS Sheave kit. I searched and found his post, and sure enough he had installed a 1mm spacer too, just as I had and his new sheave was hitting his clutch bell frame causing the noise. I tore down the unit and removed my bell frame and sure enough, there was a worn grove all around where my sheave cover screws are located. I removed the sheave, and then the 1mm spacer. As a procaution I opened the sheave assembly and checked my weights, etc. All was well. Reassembled and fired up the Blue Devil. Behold, a miracle, no Tawang-Bang-Bang. Thank you BadM0nkey for sharing your problem with us. It sure saved me a lot of time straightening out my own Tawang-Bang-Bang.

Glad to be of help. Mine sounded like a bell ringing.
