2012 Txc 310 Black Head Vs The 13,14 Red Head

what are the actual differences between the heads? what else is different? do all the original electric starters have problems? im looking at a 12 but wonder if i should hold out for a 13+

Its more of an unlucky issue. I have had three 310s, 2011 and 2014 TE and 2014 TXC. Same starter on them all except for hardened parts on the R. Have not had any problems with them during my ownership (+400 hours together). Though I know more than many have had more than enough of them. The new owner of the TXC have had some problems after I sold it but it works now. The most important different between black and redhead is the fuel injection. Mikuni vs Keihin where the Keihin is the one to prefer BIG time. KYB or Sachs, they are both great suspensions but they need som love to work as you would like. Even though you have got into some problems. Try to fix them. In my opinion one of the best enduro bikes ever built.
