Just thought I'd update you guys on this thing.... turns out one of my reed petals had broke off and was wedged all weird between the cage and the cylinder.... i'm putting some v force reeds in there and tweaking the jetting and all should be well

My air screws are 1 1/2 turns open and my mains are 340. Should i try opening the screws more?

Maybe I'm just hoping for the best but could my issue be from having too big of a port job?

This engine was literally fun for the first time last week. I find it hard to believe that the pistons/rings/etc. would be bad already unless the mechanics tore the shit out of it. They claim that the compression is great.

The choke tube is there...it looks like i just have some overflow tubes or breathers missing (which i will put on tonight). I talked to the mechanic again and he is telling me that it just needs time to break in all the way...Another guy said I should mill the heads to work better with the porting job on the jugs. I'm all ears for suggestion now....the thing seems to run great when its warm.

It looks like I'm missing some tubes on my carbs...would this be a big enough issue to keep it from starting cold?

I have FMF fattys and turbine core II silencers with a custom aluminum airbox (twin k&n filter). The lid is on the box but it has vents on both sides for the filters. The jugs were ported by Kustom Kraft. I don't know the numbers on the jets, still kinda new. I got a dynojet(correction from earlier) stage 3 kit and can't find the exact specs on it. The plugs look kind of dirty but I had it running earlier. I live in southern indiana so it is in the 80s but humid, elevation is like 500 ft.

The stage 3 cdi is supposed to be a higher performance rev box and the jet kit is a dynatech that says stage 3 as well. The choke doesn't do jack. I can seriously kick for like 20 minutes and nothing happens. I have to push it up and down the block like 6 times before it will start. Once warm it screams. However, I think it could use some better tuning but since the engine is so new I can't really push it hard enough to tell.

So I just had a Banshee engine entirely rebuilt, with a stage 3 CDI and stage 3 jet kit installed. I'm running 110 octane mixed 50:50 with 93. The motor is far from broke in, and the mechanic claims it is tuned well, but this thing will not kick start for anything when it is cold. I have to "bump" start it, usually down a hill to get it going. Once warm it starts every kick. Is there some trick I'm missing here? I am somewhat new to jetting but something tells me that there is a quick fix to this issue.
