UPDATE 9/15/08 - I spent a couple of hours the shop wrapping up the SYE conversion on the 241. I gotta admit, it wasn't that bad. JB Conversions did a great job on their instructions. The only question I ran into was which direction to install the blue speedo gear...I didn't pay attention when I took it off. The hardest part of the install was removing and installing the snap rings. There are 4 to remove in the tear down and 3 to install on the build. For anyone looking to do this conversion in the future, invest in a good set of snap ring pliers. The snap rings look like the one shown below. They don't have the holes in the tips that I'm used to seeing.
All in all it was a good evening. Here's the finished SYE 241:
Tomorrow night: remove the TH350/205 combo and put it up for sale.
