ORIGINAL: ABELL
I have a Saito 100. The exhaust tube on the muffler is tapered. No amount of zip ties would keep it on. Clean or not. I put a ridge around the exhaust with JB Weld and had no more trouble. The newer Satio's have a muffler with a ridge machined on it. Seems like Saito realized the problem and corrected it.
AGAIN.... I also JB weld a lip on the exhaust tip. Works great and an easy, secure fix.
