Screwing air mixture screw in usually makes it sound better. Also at half choke it idles a lot stronger and sounds a lot better. Without it choked, idle is very weak.

Trying to diagnose some low end / idle issues with this bike. Going through everything possible. Have a couple of different carb bowls for my stock carbs. For my choke side carb, I have a bowl that has a jet in it that you can actually unscrew and take out. And I have a bowl with a jet in it that you cannot take out. The one with the jet has a larger opening. If I blow compressed air into it, it shoots out pretty strong from the other opening. The other bowl with the jet you cannot take out has a lot smaller of an opening. When I blow compressed air, there is more of a restriction when it blows out of the other hole..but still does blow through. Any difference in using either one?

right now, I have 32.5 pilots. Idle sounds little weak still. When I pull choke out halfway, the idle gets a lot stronger and sounds a lot better.

Make sure your float height is set correctly. I set mine to around 21mm. Couple YouTube vids on how to adjust and set height. I’ve had this prob before and checked everything electrically , etc. ended up adjusting float height in one carb and fixed issue

Def check float height!! South Texas banshee and couple others have YouTube vids on how to adjust and set them.

Appreciate the info Chris. On your 3rd point about the mikuni jets... how would you tell the difference between a mikuni pilot jet and a pilot that is not mikuni but looks the same?

You would like them as in you want some? I have some laying around

I had pretty much this exact setup but was running with the lid off, and ran great. I don’t think it would hurt to go down to 260 and see what she does. Def try to do a plug chop or at least pull them after first ride and see what they look like

Recently picked up a banshee mods - fmfs, vforce 3 reeds with new petals, brand new pod filters, TORS delete Compression just about 150psi on each side leak down Tested and perfect got the bike and it had been sitting for long time- ran like shit. Cleaned out carbs really good. There were gold needles , but I replaced them back to stock needles. Pilot jet had no markings on it, so after some research, I started at 30. Bogged off throttle and wanted to die as I unscrewed air mix screw. At .5 turns it idles and revved a little better, so I went up to 32.5 pilot and at about 1.5 turns right now. Main jets were 340. Needle on 2nd clip from top. At sea level. when coming off throttle, it struggles a little/ wants to stall, but runs great when past that point. If I give it a good rip down the street, when I get to a higher gear/rpm and pull in clutch, the bike will stall. carbs are synced with sync tool, and carbs are rebuilt with float height about 21mm both sides.

I’ve been researching for a long time and I can’t find the answers I’m looking for. looking for some input. can someone please tell me what markings you would find on the mikuni 26 mm vs the 28mm? my carb on the side says 2GU 01. I was told these are stock but when I type this number into google, everything about the 28mm comes up. also, what is length of stock banshee needle and how many grooves are on it?

Internally, what is happening when bike is turned off, and in gear. You roll the bike but the clutch assembly doesn't move? When you roll the bike in gear, shouldn't clutch want to turn, which would spin crank?

what were the symptoms when that happened?

So when I roll the bike when it's in gear, there is not much resistance. It kinda just rolls almost as if the clutch is pulled. I took out pressure plate and pulled out fibers and steels and checked out inner hub and there were some gashes in it, which may have been keeping the steels to be able to move back and forth

Yup all fibers and steels, started and ended with fiber. 120% pressure plate is sitting correct..before I put fibers in, I lined it up and made a mark just to be sure. Key way def in pto gear and shift shaft is on star. It clicks through all gears fine.

Adjusted screw in pressure plate, arrows are lined up good. pressure plate separates good when i pull clutch lever
