Default Re: Biturbo Exhaust/Chain Adjuster upgrades

Something I learned from this project is the oil from premix will find the smallest escape route and make a mess. So I guess one of the keys to fabricating an exhaust for a 2 stroke is to eliminate all exit points in the system except the obvious one. My first silencer was connected to the Biturbo Expansion Chamber with pop rivets. The B & S muffler that was inserted into the silencer housing was also connected using pop rivets. Unfortunately, pop rivets do not provide a tight seal and oil eventually leaked onto the exhaust. I corrected the problem by using a one-piece silencer and connected it using a hose clamp instead of pop rivets. So far, so good, and it sound much better!
