SR311 Posted March 24, 2013 Report Share Posted March 24, 2013 I realize this thread is full of "Need help" topics, and unfortunately mine is going to be more of the same. Here's the story, I bought my Banshee the day I turned 18 in 2004. It's a 2001 that I bought from a dealer with some modifications already made: -FMF gnarly pipes into power core 2 silencers -Single filter K&N intake in a stock box with no top -Boost bottle -Bored .35 over I don't believe there's been any porting work done, and the carbs are the original carbs. Those are the modifications that I know of when I originally bought the machine. In 2009 I did a rebuild and bored to the next size up, .40 over but didn't change any jetting or anything like that. Currently I'm rebuilding again with the same bore size and adding Vforce reeds and eliminating the TORS. I also scored a very nice stock head which has the domes chambered. I want to know what my proper jetting should be. I live in Vermont and I spend my time woods riding, I run BR8ES plugs and 93 octane mixed 32:1. Any other information I need to provide let me know, I would really appreciate the help. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted March 24, 2013 Report Share Posted March 24, 2013 First, lose the boost bottle. If start at 290 main, 27.5 pilot and needle in the middle. Air screw .5-2.5 turns out. Quote Link to comment Share on other sites More sharing options...
SR311 Posted March 24, 2013 Author Report Share Posted March 24, 2013 I've noticed a lot of hate regarding the boost bottle so I've been thinking about getting rid of it. It's just a gimmick? Quote Link to comment Share on other sites More sharing options...

oldskool Posted March 25, 2013 Report Share Posted March 25, 2013 Yeah, but everybody has had one. lol The selling point was that the boost bottle would store pressure from the reeds snapping shut, then when the reeds opened again, Bam, a boost of air/gas pushed into the cylinder. They sold a ton of these things Quote Link to comment Share on other sites More sharing options...
