i'm having a 2006 banshee that has mikuni carbs with 280 main jet and 25 pilot jet. I tried many times tuning it with 1.1/2 turn but it seemed like it was running way to lean. So, I thought that i should try turning the air mix screw all the way in. surprisingly, it started running like a beast and it sounded awesome, but i have heard that when you turn the screw all the way it will cut air from getting into the engine. So, it should die right away. i don't know if my pilot jet is the problem or there is air leak somewhere. my mods are toomey t5 pipes, pro design cool head, and k&n filters

I noticed that left carb(the one with choke) leaks fuel from the gasket when it's not running, I think it's sucking air in and cause lean condition

i will buy new intakes since there is higher chance that it leaks air, and i'm gonna install 27.5 pilot with 280 main since i don't have 300 in hand. hopefully, I can ride it next weekend in the desert

the thing is i don't have leakdown or compression test tools and i have to buy them online and that might be two weeks of waiting :\ i have 280 main jet in my garage i can put them on but where i live is never cold these day, it is always above 80 f. And I think i have stock needle not toomey ones

Well, i found that one of the spark plugs were bent. So, I bought a new one, and now there is no more backfire. I believe I have dropped that spark plug when i installed it so maybe that's why it bent. Also, i have turned air mix scrow all the way in, and it idles pretty good. i'm not sure that was the problem. I live in pretty dry area and way too worm for winter like about 86 f and 2000 feet above sea level. is what i did right? and well it cost other problem?

recently, I did top and bottom end for my 2005 Banshee and bored my cylinders 0.50 over. My banshee won't idle and right side backfires when i rev it. carbs synced and cleaned, they have 260 main jet and 25 pilot jet, reeds seemed fine when i installed them no cracks or anything looked bad. I have K&N filters and Toomey pipes and boost bottle with a crack in the intake but i put silicone on the crack to seat it up. i changed my spark plugs with no improvement. Sadly. i can't do a compression test or leak down test. any idea that may help diagnose the issue

I have done engine split for the first time for a sheeee which was suffering from rich condition since crank seal was bad. I did everything right and put the engine together. When i start the engine it works as it should, but there is more smoke in the left side (stator side) than the right side, which might be carbs insynced. I have tried to sync carbs, but there something called switch assy i think located on top of the carbs that don't work or they seem broken. Any idea how to fix these switch assy or can I sync them carbs without them. Please help! My banshee is 2005 bored 0.50 with Yamaha pistons. carbs are Mikuni

Yes there is metal every oil change.

I have a 2005 banshee and I'm splitting the case change crank seal. I noticed that there is play in transmission where the basket sets on is it ok if it has play or i have to change bearings
