I have a Tanaka 47R 2.8 hp racing engine on my Diamondback bike. After recently installing a Tanaka three-piece expansion pipe, I am plagued with leaks at three separate slip-fit connections. The head pipe bolts nicely onto the cylinder, so that's not a problem with its flange gasket. This 29mm pipe then slip-connects to the neck of the fat chamber. This leak is 24" below my chin. Exhaust gas leaks there and burns my eyes, so I bought a VERSACHEM high temperature exhaust bandage wrap kit(for cars). It's an epoxy/fiberglas mesh/aluminum tape combination I used to wrap and seal the large slip-fit pipe below my chin. At the pipe's exit, there's a 15mm slip-fit which I also wrapped and sealed.
The last slip-fit is from the silencer's tip to the OEM muffler. There is a slip-fit adaptor w/retaining spring, but it's designed to "bottom out" onto the silencer. This leaves no overlap to seal. I just know it'll be a waste of time and materials to use the fiberglas/aluminum tape wrap. I also bought a CAR-GO high temperature exhaust repair kit. It looks like liquid in a bottle that turns hard like epoxy. This MIGHT work, but not sure.
Does anyone have any suggestions how to seal this connection? The outside diameter of the flange adaptor is mm. Maybe a high-temperature oil seal like something from an old VW pushrod tube would fit and work.
Any suggestions?
Here's the Tanaka engine and the three-piece pipe:
