I bought my son a ttr 125 in 2006 brand new. it has never ran correctly. I\´ve taken it to the local (40 miles away)dealer 4 times, to which they get it running, it will run for an hour or so, but then crap out. it seems that the govener(throtle regulator) fouls the plugs, but there is more than that going on. Has anyone else had these problems? any fixes that you know of? The dealer ship to sell the bike told me that when he was ready they could remove the throtle regulator, but now say it\´s a factory thing that they cannot touch. also looking for other performance upgrades.
