So I gave up the ghost on trying a fuel injection conversion on my KZ400. Wanting to stay away from the factory twin carb + air box for ease of meddling with the bike. I have a 2-1 intake and a Mikuni VM34. I know its a bit much for the bike according to most people, but it's what I got. I want to say my pilot is a 27.5 and either a 120 or a 140 for the main. I dont remember how its set up as the last I touched them were two years ago and I set up according to a person that lived at a similar altitude as me (~2300-2400 ft).
Well with whatever I got in in, I am get a nice steady idle @ ~ 1200 rpm (about right for the this bike, technically a little low iirc. Tons of power once you get in the RPM a little bit. I am having two main issues: hesitation when "blipping" the throttle (something I understand true slide carburetors dont like in general, but mine seems a little excessive) and a hanging RPM when coming off the throttle.
Bike is currently set up with Stock pipes with Sankei mufflers (appears to be OEM spec muffler?).
My understanding is that I need too go a step higher on my pilot (since tuning idle has my screw at ~1 turn out) and would the transition hesitation be a needle clip adjustment?
EDIT: it was a 27.5 pilot, but a 150 main. I found the 22 pilot that came with the carb, tried that and same result, so I am assuming lean and not overly rich. Cant seem to find the rest of my jets I had ordered so I will have to order them again.
