2003 RM 125 - Hard Carbon Build Up in Expansion Chamber
Posted 20 February 2012 - 06:03 PM
1) What would cause that? Running too rich at one point?
2) How would the carbon build up effect performance?
3) How do I remove the hard carbon build up? Can I fill the pipe with something that would remove the build up?

I put a buch of oven cleaner inside mine and closed up the openings. It did a marginal job at best. That was also suggested in the post I read.

This is believable to me because a propane torch was how I ended up cleaning the inside baffle of my silencer. Good Luck

I'm assuming that this could have had a pretty significant negative effect on performance since the inside diameter of the pipe was smaller than designed.....right?

And yes, a big build up does affect performance, 2 strokes are very sensitive to the shape and thermal properties of the expansion chamber.

Great stuff, but handle it very carefully. Wear decent protective gear (especially goggles, gloves etc), and add the crystals to water slowly to minimise the reaction (the reaction will cause it to get very hot too). This info may be useful too:
