MC18 Exhaust and cannister decoke

Mon Mar 11, 2013 12:19 am » Post: #1 » Download Post

Hi All,

I have to decoke the exhaust pipes on my R6K, and was wondering... I am planning on cleaning the expansions out using the acetylene torch method, this seems to be very affective and quick, but surely I cannot do the same to the cannisters? They are standard Honda/Sankei cannisters, but the one is very clogged up, so I need to clean it out. I would think that there is some sort of exhaust packing in there that will burn up if I apply the acetylene torch to them. Could anyone please advise me on the best way to clean the cannisters out?

Thanks.

Jacques.

Hi Tuckerbug,

These two Youtube clips are actually exactly the ones I was looking at when deciding to ask this question. The one where he does the expansions looks like it works ok, but when he does the cannisters it does not look all that well.

Think I might end up cutting the cans open and riveting them back together like Andy suggested in his post.

Thanks.

-UPDATE-

Nobody around here seems to have an oxy/acetylene torch that wants to hire it to me, and the people who do have are not willing to let me clean the pipes at their place because of the mess it makes. So I had to resort to the caustic soda method. Cant really say that I am happy with the results, but after weighing the expansions before and after, it seems it has almost lost a quarter of their weight in carbon deposits and unburned two stroke.

Got around to taking my Sankei cans apart... quite interesting and I am amazed at the amount of carbon build up inside of them. Managed to separate the metal baffle from the aluminium cover, and I am planning on having a baffle BBQ this evening.

Hello, Urkie

I understand the sankei cans are the std ones. If so, how did you take them apart?

At this moment I have mine separated from the chambers and ready to clean them, but ...
