Awh man just did more reading and I think I’m starting to get it. A longer taper means less straight section. The straight section is really what is ganna help keep my low throttle position mixture lean. It blocks THE MOST of the hole possible. Longer taper is giving my bike gas sooner since the taper takes up more of the needle. Hmmmm learning in real time. Soooo maybe shortest taper with a thinner tip? Yeah? Crap they don’t have that. Seems the 1mm tip is only available in 22mm taper and longer. So w8 may be my man. 1.4 tip same as the w7 but 2mm shorter taper (edited)
