I had a similar hiccup at 3/4 to WOT with the stock carb. I'm at ~5,500 ft and trying to jet for 8000+. The stock jet is a 108. I got 105 down to 98 trying to get lean enough. The bike ran well enough but had an inconsistent sputtered/hesitated at near/WOT. Tried a number of different jets, idle screw adj., and needle positions. Never really resolved the issue until I swapped to the Mikuni carb everyone else is running. I believe I'm using a 100 main and 25 slow jet (haven't looked at it in a few months). Have the after market exhaust, de-smogged, stock intake/air filter, stock gearing (17/50). Still not getting the advertized top end speed but I am getting up to 64 - 65 MPH per GPS (190# rider + gear) and does pull hills in top gear much better.
