Gazlay43 Posted January 14, 2018 Report Posted January 14, 2018 So I bought a Banshee off a guy who lived at about 700 feet above sea level, which is close to the elevation I plan on riding most of the time. I live at around 2000 feet above sea level. It ran pretty good when I picked it up. Got it home and noticed the choke tube was missing and he also had the slides in the wrong carbs. He was was running an aftermarket uni filter with no lid. I switched to K&N pods. Now that I have the carbs back together with the choke tube and slides in their proper places, it's not running well at all. Pulled the carbs and they have 280 mains and 25 pilots. It currently has Toomey pipes and pod filters. Being that I'm at 2000 feet, is a 280 main still too lean? I did some searching in the jetting thread and saw that a lot of guys are running a 27.5 pilot and much larger mains than what I have. Sent from my iPhone using Tapatalk Quote
hoppedupandcutdown Posted January 14, 2018 Report Posted January 14, 2018 Just to triple check... Quote
hoppedupandcutdown Posted January 14, 2018 Report Posted January 14, 2018 And I run 280 and 25 w/ Toomeys and open box at 1500ft no problem. You're a little higher so you won't be leaner. Double check the mains, if it ran OK with the slides in backwards, they had to be 200's ish. Quote
Gazlay43 Posted January 15, 2018 Author Report Posted January 15, 2018 Ya originally he had the flat side of the slide towards the filter so I fixed that. The mains are definitely 280s. I'm not sure why it's running so bad now. He said the carbs were just rebuilt but you know how that goes. I'll pull em off again and give the jets a good cleaning and go from there Sent from my iPhone using Tapatalk Quote
Gazlay43 Posted January 15, 2018 Author Report Posted January 15, 2018 What are your air screws at?Sent from my iPhone using Tapatalk Quote
Gazlay43 Posted January 15, 2018 Author Report Posted January 15, 2018 Most of the pipe manufactures recommend running a 320 main if you don't have an airbox. Starting to worry that the 280 mains I have will be too lean where I ride. Some say stock pilot is fine, some recommend a 30. Guess I'll have to order a kit and figure out what the bike likes.

I'm thinking the 280 might be a little lean there.Sent from my iPhone using Tapatalk Quote
Gazlay43 Posted January 19, 2018 Author Report Posted January 19, 2018 Also noticed that the carb bowls were switched as well. Cleaning out the carbs real well and putting the bowls on the proper carb. Hopefully that fixes everything Sent from my iPhone using Tapatalk Quote
Gazlay43 Posted January 21, 2018 Author Report Posted January 21, 2018 All fixed. Definitely needs larger main jets though so I ordered a set of 320's like DMC suggests for their pipes with no airbox Sent from my iPhone using Tapatalk Quote
