Stock banshee jet sizes?

[mattb348]

OK I do know that the stock main jet for my 2002 banshee is a #200, according to the manual. But the POS doesn't say what the stock pilot jet size is! Anyone here know?

 

Also, I was told by a member here that if I put on pro circuit pipes & silencers (my banshee is 100% stock, and I'm only putting pipes on it), then I'll have to switch to #280 main jets, and #27.5 pilots. Doesn't this seem like a huge step up in sizes for just putting on pipes?

 

Lastly, what increments do the jet sizes go up/down in??? like for instance, what is the next step up from a #200 main? like 210 or something? And what about the pilot?

 

Thanks a million guys!

I put on a set of Pro Cicuits on my Banshee when it was stock. I went to 280 mains and that was it. I didn't need to change my pilots at all. I live at 700 feet above sea level.

stock pilot is 25. mains go up/down by 10, pilots go up/down by 2.5

280's are a pretty common jet size, recommended by most manufacturers after installing pipes. I did pipes, removed airbox, reeds all in one move and went from the stock 200 to 330 (yes it's spot on and I could post pics for the naysayers)which seemed unheard of but that is what the bike took. If you are leaving the stock airbox in place 280's should be pretty close, your elevation and air temp will play a part, if you post that we could probably get you very near to perfect, but plug color is the determinant. You probably shouldn't have to go up on the pilots if pipes are all you're doing at this point. Once you do airbox/filter changes and/or reeds you'll probably need to bump the pilot up.

Thank you very much for the help. I will be riding in the temperature range of like 65-85 F. And my elevation is standard. Does it sound like 280 main is the right choice here?

 

Thanks.

yea that sounds good if you have your snorkel off, but if you take the whole lid off and put on a K&N put in a 330 main.

This is more of a secondary question than a reply I guess. My bike is stock except the head has been shaved .025" and it has been bored out .010" for new stock pistons.  I was wondering if there would be any benefit or danger to jetting a little stronger. Has anyone ever heard of how strong a stock bike can successfully be jetted to before causing problems?

You will want to plug chop your bike after your jet install (do research what a plug chop is) thats really the best way to know if rich or lean. But if you run it to rich your bike will dog and run like crap on the top end with too much fuel but if not jetted enough it might run pretty strong but not for long cuz theres too much air and not enough fuel

I need help, I got a 2005 banshee it just got built but I don’t think they rejetted the carbs but what do y’all think I should run on my main and pilot jets, I have an air box with a high flow k&n filter and I have Toomey T5 pipes on them, what do y’all recommend?

Depending on your elevation...But 280 main and a 27.5 or stock 25 pilot will be close.

Hello, I have a 2002 with T5’s and pod filters, +2° timing, stock carbs. My jets are 25 pilots, 310 mains (they’re about 1 size above where I could be, but I played it safe with a nice caramel color, I’d rather be slightly rich and not rebuild too soon) needle on the 4th notch, and mine pulls very well and smooth throughout the powerband

Stock is 25 pilot, 200 main. 

If you do a pro circuit exhaust, the 27.5 pilot 280 mains is pretty close. Filter set up could change the main a size up if you have pods.

Where’s the AF ratio at? And give that thing 27.5 pilot and 2 more degrees of timing.

The tuner I went to didn’t use An AFR sensor. Why do you say go up on the pilot and add more timing? When I get a chance I’ll take a pic of my plugs and see what you think

Experience and knowledge after countless set ups and dyno pulls. Plus the 25 pilot is for stock pipes and intake. You’ve got it breathing better, so now it needs to be fed better. And 4 degrees timing on a basic stock ish bolt ons set up always do well with 4degrees if you’re running premium fuel.
