1 New Exhaust equals Poor Performance Fri Mar 21, 2014 11:25 pm

Hi all,
I have been working on modifying my k100 and am getting near completion. My issue is that I took my bike for a test ride about 4 weeks ago with the standard exhaust and was impressed in the way it ran. I then took the bike to a friends house who disconnected the battery and set about making a custom Collector to allow me to fit a different muffler. The collector is around 40mm at its smallest diameter, and from this I fitted a shorty reverse cone muffler.
I picked the bike up and reconnected the battery and the bike started without fault. I took it for a ride and the bike seemed to lack power and acceleration and was disappointing to ride. Suspecting restriction being the cause I removed the Baffle from the Muffler and took for another ride with no change to performance..
Am I right in suspecting that the collector is causing restriction and therefore poor performance. Or is there a possibility that the battery being disconnected for 4 weeks has affected the Computer (doubtful) or as with some car CPU's does the computer have the ability to self teach based on bike operating feedback.
I have seen these Mufflers fitted to other K100 bikes but have not read about the issues I am having.
Thoughts?
