I wouldnt. As well of machined pieces TS makes, I am sure he has the proper clearance setup for the correct dome / crank combo. I would highly doubt he would leave so much extra room to get away with running a +1 crank. I would try a +2mm 15:1 dome with a +1 crank before I would try a stock stroke dome with a +1 crank.Can you run a 1mm crank with a standard stroke 13:1 dome? Hopefully there will be enough clearance and just be higher compression.
