Vibration issues

[Tom229]

Hi everyone, I am new to Trophy forum. I recently purchased number 229 and there is a loud vibration which occurs specifically between about 4800 and 5300 rpm which really ruins the driving experience. Does anyone have any ideas what this might be?

My only thought is maybe the exhaust fouling on the bodywork at certain revs but I could be completely wrong.

Check the rear heat shields above the boxes as these can break and vibrate,also the centre box is known to fall apart inside and vibrate.This is assuming its a standard exhaust.
