Struggled for a while finding a suitable adapter to get rid of the giant, heavy stock muffler on my bike and put on something lighter and repackable. The problem stems from the fact that the end of the pipe on the 75-76 Honda elsinore 250s were approximately 1.7" in diameter because there is a small built-in stinger at the end of the pipe (probably because most racers in the day just took the silencer off and ran it with nothing). The silencer has a 1.25" OD pipe. Used a plumbing adapter for a while, but too heavy and ungainly and didn't work that well. Made an adapter out of auto exhaust pipe, same story. So I finally bought two radiator hoses. One small diameter that slips over the muffler inlet. And a larger hose with just the right bend in it so the muffler angles up nicely, rather than hanging out straight like it used to. Slipped a piece of the larger hose over the end of the pipe and the piece of hose I put on the inlet of the muffler. Looks great (hey at least I didn't braze or clamp a pop can on) and so far works very well. I've ridden it five times, but not longer than 35 minutes at any time. I tend to think it got as hot in that 35 minutes as it is ever going to. But I don't know. Hose felt about as hot as a radiator hose gets, but I didn't measure the temperature.
