We'll that is another link about power loss at higher rpm or fuel starvation when pushing the bike above a certain speed,load or rpm.
Mine won't last out the driveway dies while warming up but always restarts only to die again. The overheating fuel pump theory sounds feasible but guess can only be confirmed by dealer checking ECU computer. Bike does not run long enough to warm up past one bar.
Drag I'm down to one none functioning bike. Tried to buy the new duke 1290 but dealer never got one....missing my tiger 800 now...
