About this STS D.21T motor. I really like the power. it has low and top end. I bought one mid season last year. I broke it in, then run low speeds for one race day then run it for 2 more weeks at full out. I was in the warm up laps for the main on the 4th week out and the crank broke. I got the parts to replace it but the race season was over by then. So this year I took it out and run 6 tanks thru it and guess what??? Today the new crank broke in the same place as the first one did. What’s up with that?
Have any of you guys ever heard of this happening to this motor before?
