I was riding one day turn the bike off in middle of trail for a break.. Kicked it like crazy ended up pushing it a mile through a equestrian center wher I wasn't supposed to be.. Anyways after that I replaced the coil and stator and the bike would start it would run fine for about 5-10minutes when it got to temp or hot it would start this spuddering.. When you crank the throttle it dosent want to raise in rmps and make this repative noise.. I was told it could be the cdi box "brain box"??? Has anyone heard of this problem anything like it?
