GasX, I had a co-worker who works in the sheet metal department where I work,bend a piece of metal in a stair step design and then punch holes for the bolts to the engine and holes to use the included u-bolt. Seems to work just fine. I did not want to drill thru the frame.
Thanks again to all on the compliments and suggestions that I leave the original sproket and just ride thru the break in.
I can see where this hobby can be addicting.
