Just got my banshee running weird

[03banshee88]

So I got this 03 banshee has Athena 392cc big bore trinity 2 to 1 carb set up and full fmf powercore pipes with a modded lid air box. Now it starts right up everytime but it has like no power on low rpms until I floor it in first it bogs hits power band then runs great in high rpms. Not really sure where I should start

Compression test would be a good start.

Let us know jet sizes in your carbs , carb type, compression, timings dome size

2-1 carbs depend big time on needle selection , if it's a 33 I liked s dek and dej , 35 mm carb liked eek , is it a pj pwk?

[03banshee88]

It's a keihin pwk how can you determine what size though I haven't found any markings on it

Probably need mag glass to see marking, unless cheep no name needle.

So it has a 170 main jet and a 55 pilot jet and it seems to have stock reeds still in it as well. Doesn't that jetting seem kind of low for it being a big bore with all the other add ons
