30 years ago, I used to take an M117 timing chain, cut it in half and put the two pieces side by side and make a 4 row belt the Harley rideres were jealous of. I tried it again with my last chain and found that if I did that the belt would be too small. So it will have to be either a ladies double row belt, Or I will have to wait untill I do another timing chain job. The M117 engine must have gotten smaller over the years.
