Thanks David and do the rest of u really have nothing better to do. I figure your all sitting at Burger King using the wifi eating double whoppers just waiting for someone to ask a serious question so you can sit there get fatter and be idiots

Honestly the map updates, a good plug, the tps, good fuel with higher octane (97 is fine), good premix, the TC125 seems to be in better shape than the Ktm as far as issues. I don’t trust the top ends, the pistons crack early, but an ecu tune in my opinion will work great for the 125. I tested about 5 different maps and settled on the one he uses most now and the bike is a ripper. tell him I sent you, he increased the price to $249, he may knock off a few bucks with the name drop...
