I agree w/ Jody. We are here to share knowledge and our opinions you don't have to agree with [8D] Always liked [link=http://tweakshop.net/images/tettra.jpg]to tweak things[/link] and lost one YS110 muffler only in 6 years, sorry.

If you use screws of the correct length and some heat resistant thread locker w/ the stock gasket on a clean surface, the muffler will never come off, unless it cracks of course.

Owh, and about Jody. I'm sure he is very knowledgeable w/ what he's doing for a living, but that doesn't mean we're not entitled to our own opinion.
