Gsx 1400

[Baz 460]

Hi. I recently bought a 2004 GSX 1400, in mint condition, it has done 40,000 klm's and runs like a clock.

But I have an annoying problem with it, that has just started. When you give it a sharp fist full of throttle, it hesitates, then takes off. If you screw it on gradually, it doesn't miss a beat, only under full rapid throttle.
I unfortunately am not mechanically minded, so have had to take it to one of the local bike shop here in Cairns.
A bit of a run down is as follows.
No fault shows up on computer.
New plugs.
New and adjusted TPI.
New battery.
Coils tested, wires checked.
After putting the new TPI on and adjusting it, he put it back on the dyno, and it seemed to be OK, took it out for a test ride, same problem
The mechanic thinks it is electrical, but can't seem to find anything.

Hey mate, welcome aboard. Tony has one of these and knows a bit about them, so he may have your answer. I'm sure he'll be around soon.
