MartinB re bypass adjust - the air bypass is a brass slot head screw on the EFi throttle body practically hidden under the seat. The entire throttle body can be rotated (Jubilee clip) towards you to gain access. Main purpose is to set the idle speed but -
But with idle set slow as supplied closing the throttle practically propelled me over the bars and cracking it open again resulted in nothing, nothing, nothing, nothing, OMG! wheel off the ground (which is not funny in a tight bend). Throttle basically acting as an on-off switch, not gradual feed in of power. Taking excess slack out of the throttle cables did not do the trick.
Turning the bypass maybe less than 90° increased idle by 50-100rpm, not a lot, but did remove most of the flat spot.
Replacing the exhaust with free-flow 50s, K&N and PCV, and repeating the set up exercise has dialled out the flat spot to my satisfaction. The point of fitting the goodies was not specifically to increase power but to get the motor pick up smoother and more tractable, not so all or nothing.
