I used a short section of 1-1/4” X 1-1/4” square tubing that I took a rat tail file to and made two rounded groves on opposite sides to guide the larger u-bolt. Next I used a short section of 5/8” round bar stock that I also cut a round grove in the end, to use as ram to push the larger u-bolt down in the square tubing to form it to the size I needed. I have one of those hydraulic shop presses from Harbor Freight that I used to do the work. I used a short section of ½” X ½” square bar stock for the clamp; I drilled two holes to fit on the u-bolt. The u-bolt is a ¼” by 20 thread bolt size. I originally tried to use some all thread rods but it would snap, and I even tried to bend some bolts from Home Depot with no better results. If I couldn’t find a u-bolt to fit I was going to use some ¼” rod stock which is soft enough not to snap in the jig. I would have had to bend a few to see how they would work and where I could cut some threads on the section of rod before I bent it. Do you have any pics of your setup and how is it working out for you.

My governor is tie raped and I have the JW8 drive clutch and the JW8 driven clutch (FBT) installed with J55 shorter belt. I have the Jake’s Power Spring Kit Yamaha G29 (item 6222) installed in the driven clutch. I have noticed that the Power spring in the driven clutch seems to shift to high gear very quickly and is slow to return to low gear, but does go back to low gear when stopping. I am considering reinstalling the original spring and clocking it to a higher setting to see if it performs better than the Power spring.
