    Thanks

    Yeah I’m quite keen to get the Dr on the dyno too for a baseline before I put a high compression piston in.

    So, my bike stopped idleing recently and at the same time the midrange improved HUGELY, it now comes on in a big rush.

    On investigation I discovered the extended fuel mixture screw has unwound itself and dropped out of the carb.

    I want to get the bike idling again but not lose that huge midrange rush. With the fuel screw removed that means more fuel is getting in through the idle system, so I should go up a size on the idle jet?
