I run a 195 for the pilot, but I cant remember what the other one is.

Do you really??? they make em that big??? or are you runnin a 195 main???

I’ve ran as high as a 205 when I was testing. So yes they come that big. I just cant remember what the other one is. The carb I got had a 185 in it and all I did was change the main till my plug looked good. I didn’t need to mess with anything else. She runs great where it’s at now. It started popping on decell when I got over 200 on the main jet.

What does a stock 05 450 carb come with? If the 185 it had when I got it is stock then the pilot jet should be stock because I didn’t change that one..

are you sure you have the hot start blocked off correctly? I had the same problem your having and figured out I had an air leak. If you turn down your idle all the way and it stays running, you have an air leak through the hot start

[honda400ex2003]

he has an issue somewhere with it, a 182 in a 416 is quite big

mid 170s would be a maximum imo, thats pushing a full exhaust with an open lid and a port job.

a 52 pilot at around 3 turns out should get the idle pretty nice and running then needle on the 3rd notch would be where i start.

just my .02 though

I don’t have it in my sig but I run a 416 ported, stage 2 cam, stock head pipe (welds ground) with WB slip on and a 450 carb with a 195 main jet and the lid off the air box with a stock foam filter and she runs great. She’s been that way for years with no issues.

I have power bomb header Hmf muffler open airbox I did the go big method I went up to k190 where it sputtered at wot so went to 185 and quit sputtering so I put 182 in runs great just alittle decel pop when I'm slowing down but I have to be going pretty slow. I'm going to try 180 tomarrow. With stock carb same mods I had a k178 and no decel pop 42p 2 1/2 af ran great
