919 acting up -help!
Out of the blue every gear seems to have a spot between 5,000-6,000 rpm, when accelerating, that it the engine seems to bounce rapidly and not increase in speed. If I accelerate slowly it will go all the way to red line without any problems. The only change I did from before this problem to after was have my titanium exhaust high temp powder coated and I repacked it with 2/3 the packing. Not sure if this would have made any difference as the problem didn't start till about 500 miles after.. any help would be appreciated as I dont want to spend an arm and a leg for someone at a shop to just diagnose the situation. Thanks
