In the late 1990's with the standard engine and the Twister, the exhaust flange was shortened like the example on the left. The also used a 6-32 screw to attach the muffler.
The case on the right was the normal length of the exhaust flange used from the beginning. This version uses the #5 screw size mentioned above. We have returned to this length on the latest production crankcase with the 3 webs on the front of the case. For more information click here.
