I have a 98 SRX 700 that every once in awhile bogs really bad. Its almost as if you hit the kill switch. It seems that once I bring my rpm below 2500 or so it works fine again. I thought it might be the tors so I tried disconnecting it. Still the same problem. I just finished replacing the rings and did the crankseals thinking the seals might have been the problem. Still does it. I'm at a loss.
