a factory 1200 is a 170 and an 883 is 160 main jets i think. I had a 175 in a 93 sporty with buell heads and cams ect...you dont need that big of a main jet.

I have started over if you will by putting the stock jet sizes (42 and 160) back in and stepped away for a breather for now. I have taken rather comprehensive notes on all the things going on here so I don’t lose track of the way things progress be them good or bad. It is easy to get “lost” when making tuning adjustments and I am doing my best to finger this out! But I do agree with you when you said try to go back to “normal” and see what happens there.

I agree with you brother… any jet should iron this problem out. As far as the float level is concerned, I checked the adjustment in accordance with the factory manual to make sure that it was within limits, and it was. I think when I get in tonight I am going to investigate the faulty ignition module the bike sat for several months without running and sitting is WAY worse for any piece of equipment. I think with a stage one kit (since I am moving more air) a 45 jet and a 165 jet should do just fine here. Since I am running a stock air box and mufflers with baffles installed, anything over that would be too rich!

No mention of the idle mix screw ?

A 45 pilot should flow about 9 % more fuel than a 42

What needle is in there ?

Lets check the slide diaphragm too !

Make sure we have vacuum to the VEOS so the timing will advance and retard when it should

I put the stock jets (42 and 160) back in there to start from scratch. The slide diaphragm is good to go, I held it up to a light to inspect it and saw no tears or pin holes in it. I also replaced the three vacuum lines hidden under the tank because they were dry rotted pretty bad (got “rubber dust” on my hands when I touched them!). I have heard mixed reviews and sorted advice when it comes to messing with the idle mixture screw. Some say adjust and others say don’t. I know that these bikes run lean from the factory due to EPA and emissions standards. I fear the unknown here brother. I know my way around a car carburetor OK but am still learning on a CV carburetor. Folks tell me if it is lean just step up the jets and call it a day and DO NOT mess with the IMS! What do you think?

Got new vacuum lines installed and in the propper routing and location. I wonder if the VOES took a dump?!? I am going to put a spark analyser on it in the morning to check the ignition module. Sure hope that ain't it CHA-CHING! LOL
