chipdog Posted July 4, 2004 Report Share Posted July 4, 2004 I put a Noss Machine high performance head in my 2001 banshee and it wont stop leaking around the 4 center bolts. I called Noss and they sent me a set of brass washers and acorn nut but it still leaked. I called Noss again and had them send me a new O-ring set. I completely cleaned and inspected everything and even put RTV silicone on the bolt heads but cant get it to work. I finally had the stock head shaved and put it back on. I am going to sell the NOSS hesd on E-bay and try to recoup some of the money. I love how this product looked and ran but it was just too much of a headache! Even the people at NOSS didnt know what to think. I do appreciate all the help they gave me though. DID ANYONE MENTION TORQUE SPECS. DID YOU GO AROUND THE HEAD STARTING FROM 1.IF YOU DO THAT NOTHING SHOULD LEAK. Quote Link to comment Share on other sites More sharing options...
