Exhaust pipes

Its been a while, lots of things over the summer, new bike, patio, Subaru head gasket job, baby on the way, motorcycle fell off the list.  I did get a chance to work on the expansion chambers, removing years of two stroke oil and dirt baked on to form a concrete like layer.





This side had some light surface rust, but it cleaned up real well, those other side on the other hand had a few surprises.  Here is what the final product on this side looked like:


The other side had a few issues.  It looked OK at first glance but as I scraped away the layers of grim i found several small holes that I could stick my screwdriver in.  In a 4 stroke bike this would be usable, but since the expansion chamber provides vital back pressure for the engine to run, holes are a big no no.  Fortunately, my new favorite place in the world, Sport Wheels salvage has a few bikes that are identical to mine that I can pull parts from.  I found a replacement that was in amazing shape for about $70.  Not cheap, but better than what I have been seeing on Ebay.

Next maybe I will tackle rewiring the gauge cluster, once I have fixed the gauge cluster in my truck that is.
