How do I clean the inside of a "b" pipe?

[Tuttle]

Have a "b" pipe that I got from Superjet113 that's in great shape. It has the black exhaust smudge in it. Just wondering what most people use to clean em out. I also see some polished, with what?

 

[Fathom]

Run exhaust gasses through it. That'll clean it up just fine. :haha:

Swish gasoline around in it. Or gasoline and small rocks.

for real?

Sure, why not? You can try sandblasting, but you need a sandblaster for that and it's hard to reach all the spots.

put up crushed up pieces of glass and very small rocks and shake it around. i used to to this with all my dirt bike pipes, cleans them up great after a while.

5 gallon bucket of mean grean and water does decent too....but gas and shrapnel work best because the gas will actually eat out the oil residue

People really worry about this kind of stuff!?!? :bigeyes:

I agree with what Mile9c1 suggested but instead of gas, use mineral spirits (its safer).

i can see where the people anal about every ounce of power/performance would care. i mean, those pipes are meant to work off soundwaves and all kinds of science mumbo jumbo. tlr would clean the pipes of all his racer's mx bikes (back in the 2stroke days) before a race day. he did say on the dyno it showed a difference of up to 1HP.

:banghead: :haha: And people make fun of me for wanting a light boat:haha:

I wouldn't be taking it off the ski to do this. But I figure before I do put it on or sell it, it would be better clean:biggthumpup: I'm not that anal

Are you trying to clean the inside or the outside of the chamber??

 

[FL-cracker]

big diff on a ~25hp dirtbike smartazz :cool2:

I didnt know you rode 85's saki? A strong 450f makes well over 50hp.:biggthumpup: smart azz:arms: But yea 60hp vs 60.5hp im sure is a big diffrence on a bike that most cant ride to its full potential anyways.

Bofem. I got the gas and small rocks covered.

Now what would get that outside looking good? :biggrin:

Steel whool and Mothers Aluminum polish works great for me:biggthumpup: It takes me about 30 minutes to realy get it :bling: You do have to do it alot, i usualy only polish the top since you cant see the underside anyways.

I sandblast the chambers with a pressure unit. They look like an "alumacoat" finish they do on headers and paint never peels (natural finish).

The best finish would be a ceramic type of coating.
