OESKAY Posted September 30, 2008 Report Share Posted September 30, 2008 Hello, I have a Banshee that I purchased a while ago. When I brought it, I was told that the motor was bored to 400 and another time I was told it was a 380... I really don't how big is the bore is. I purchased a Jetting Kit from Vitos and was wondering what Main-Jets does anyone recommend to use on stock carbs. Stock head, just Wiesco pistons and Toomey T5's. Any help would be appreciated.

elwilliams13 Posted September 30, 2008 Report Share Posted September 30, 2008 What elevation are you at? If sea level from 280-310 mains stock pilot maybe raise the needle 1 clip. Thats what I ran with that set up. Quote Link to comment Share on other sites More sharing options...

Thats what I ran with that set up. I'm not going to use stock jets. I have a batch ranging from 280-360. I'm looking for the most i could get. Has anyone jetted a motor with a bore of .30-.50? I truly don't know the elevation of New York City. That's a good question. Thank you for your response Quote Link to comment Share on other sites More sharing options...

Thank you for your response Ok, from what read "sea level" can play a part in tuning. I don't live on a mountain or live under the London fog. Not trying to sound like an @ss. I just need some advise on jetting. I'm trying to get my my bike correct before this weekend. Ha has anyone jetted there carbs with my set up?

locogato11283 Posted October 1, 2008 Report Share Posted October 1, 2008 i would start with 300 mains and 27.5 pilot. im betting the 300 will be too rich and youll have to drop down. but its better to start out rich then to blow something up.

Michael Jackson Posted October 1, 2008 Report Share Posted October 1, 2008 (edited) theres no possible way its 400 or 380ccs on the stock stroke and cylinder the largest size you can get out of stock cylinder, at 100 over , is about 370cc's i think you dont know the elevation of new york city? wouldnt it be sea level or damn near..you can easily google it and findout but either way your close enough to call it sea level there, what kind of air filter do you have? is the lid on or off the box? if you have the lid off id start at 300 main, leave the stock pilot, main might be rich in the hot, with winter coming that is gona chnage it though,i have a similiar setup, i run no lif and a k&n and 280 main toomey needle 3rd clip and t5s when its hot, and richen up a bit for winter Edited October 1, 2008 by Michael Jackson Quote Link to comment Share on other sites More sharing options...
OESKAY Posted October 2, 2008 Author Report Share Posted October 2, 2008 (edited) I have an K&N filter, open lid. I also have a Toomey 2 In 1 filter coming in any day. Any input? Or should I stick to the K&N. I took your advice and changed the Main-Jets to 300. I took 2 days off to work on my bike. Lets hope 300 is the key..
