who owns/uses a LM_2?

So when i full throttle it, it don't freeze up now. So the ground change must of helped. how ever i can't get my laptop to communicate with it so i can't record. and it's tough to shift and try and hole the LM-2.
my carb is breaking up on top end now and my o2 reads 14.1 when its breaking up. 14.1 is lean for full throttle but not so lean it should be popping and banging...................
