@DarrenMcKinney1

Hi Liam, I just have the standard size jet in mine. Not sure what size it is as I never had it out but I will check it out later for you. The idle mixture down the front of the car I have at around 1 and 3/4 to 2 turns. This randomly needs adjusted with changes in temp etc. I think the clip on my main jet is one nick above the centre slot. With my bike this leaves it a slight bit lean but it starts a lot easier got this way as if I put it into the middle slot it’s quite hard to start hot. But just remember all the bikes react a little different and you may need to experiment a little

Hi William. You don’t need to use the clutch on the way up the gears as long as you unload the engine by letting off the throttle briefly and on the way down you do it by letting off the throttle then quickly give it a small blip of the throttle to match revs to the increased engine speed and that’s it. By doing this you match the engine and gearbox speed and is completely harmless to the gearbox. I will have a video on it coming shortly including how to make it sound like a quick shifter.
