de carbonising expansion chamber

Machine shop guy once told me that you can use drano with water in the exhaust pipes to clean, but wear gloves cause it gets hot.

How?

Eric Gorr told me that once around 2000 when I was having plug fouling issues on a KX250, and he was right. I repacked the silencer and that bike ran great again. Ever since then 2-3 times a year I repack to keep them fresh. I honestly don't remember the "science" of it. Something about acoustic waves and back pressure. It was a long time ago he explained it to me   .

What I meant was that a different silencer will not change his jetting settings if he were to rejet before he gets it. He didn't state what silencer he has now, Even the stocker is repackable. costs less than $10 and takes less than an hour. Unless of course the core is as carbon crusted as the Expansion chamber.
