Gary had told me that if you O-ring the cylinder in combination with the copper gasket you wouldn't get anymore leaks. Now I have heard you don't need to O-Ring the cylinder if you use the copper gasket. What the hell?[img]i/expressions/face-icon-small-confused.gif[/img] With a 105mm should you O-Ring and use the copper gasket or not?

 

seems it was adamsbadds did the 105 and he had real oroblems with sealing it i think he said it sits now so he might know

 

I o-ringed the cylinder on my yfz and its holding up just fine.
