For info: Just checked my 2017 Kit built 310S SV. The workshop note does not seem to have been implemented. The new "tamiya style build manual shows a slightly different routing of the cable to previous editions. I seem to have the REAR WHEELSPEED SENSOR - 2017 reference: 300A0019A My speedo played up for about 30 minutes last week but has been ok since a stop & engine restart. However I now notice my rev counter , although on zero when ignition off, does not read below 1000 rpm seems to be ok above these figures.
