Guys I have this very strange noise coming from my R154 from what I can tell. It sounds like a clicking tin can sounding noise. I wish I could describe it better. It doesn't make it all the time but it only does it when I roll from a stop (engaging the clutch). I thought it might have been my twin disc clutch but it also does it when you are rolling and get on the gas hard initially then goes away. It also does it on low gears when you let off the gas to do some engine braking. It only makes it when you get on or off the gas initially then stops. It's not a constant noise. Another thing I thought was maybe it had to do something with the tranny mount because I am using the w55 mount and only 2 of the 4 bolts fit on the R154. I really don't know what it could be. Do any of you guys with the R154 have this issue?
