INLET 0.15 to 0.25 mm
EXHUAST 0.35 to 0.45
The Danish guys say that I need to adjust it to:
INLET 0.20mm
EXHAUST 0.30mm
What can you guys recommend that I adjust them to to lower the noise??

Not sure yet...I'll have a go on saturday with the 0.20/0.30 setup and see how it goes. This is my first TU so I don't know actually how noisy it is normally. i.e when they are set right....When you take off the engine cover to set the clearance, there are two plastic rings (or spacers). Are they ok ?
