Cleaning the exaust

[Hendrikder]

Good Day Everyone

Just a quick question, is there any need or plus side to removing the exhaust every once in awhile to clean out the carbon build up or the oil inside? I am new to the two stroke so am just in the dark about it .

ThaNKS have s good one

Its part of proper maintenance on the KDX. However if you just remove the bolt in the bottom that most likely will not be enough to clean it out. You will need an attachment for your drill that can reach inside and loosen up the crud. Def pull the pipe too and make sure its clear of oil, etc.

Not sure if you have an aftermarket silencer but if you do, repack it!

Yes.

Check your jetting to make sure it is not letting too much oily exhaust by.

Do you have the stock exhaust pipe and spark arrestor? The cleaning method will vary based on stock or aftermarket. Also, which KDX do you have??

I have a 2005 KDX 200, I run a FMF Gnarly pipe ,and it does have the spark arrest on. I will definitely pull the exhaust and clean can I clean it with engine cleaner or should I use something more specific and every how many hours would you say I should do it?

Thank You very much

Is it the stock spark arrestor? Cleaning a stock spark arrestor is different than cleaning an aftermarket one.

On the pipe, there are many methods. Here are just a few.

If the pipe has a lot of carbon near the front, then get a narrow chisel or old screwdriver and start chipping it out.

Put gravel in the pipe, cap both ends, then give it a shake to break up baked on carbon.

Get a long braided steel wire and put it in a drill on LOW!!! speed. As the end whips around inside, it will break up carbon. DO NOT let the end whip out. Also, it will cause an AWFUL amount of dust. Wear a mask and safety glasses!


Blow the dust out with compressed air afterwards.

The majority of the problem is going to be at the front.

Thank you for the advice, I will definitely remove the pipe and clean it out a bit .

I run the FMF arrestor, not the stock pipe.

So you have an FMF pipe and an FMF spark arrestor (muffler)?

It will be somewhat similar to this:
