New Banshee owner needs jetting help

[xrjeff]

I just picked up a 2002 Banshee, and rode it at Glamis this past weekend. It had zero bottom end, but pulled fairly hard on the top end. Throttle response is crisp and clean sitting still, and it has the idle kit installed. The bike has a set of chrome pipes w/aluminum silencers on it, but I can't find a name on them. The only thing I saw was "SCP" on the silencer mounting tabs. It also has the TORS kit removed and a set of K&N's w/Outerwears hanging on the back of the carbs. I also own a 2005 YFZ450, and I know the Banshee won't have torque like this bike, but it still seems it should be running better. Even though the top end pulled strong, most hills had to be taken in second gear to stay in the power band (otherwise it would bog down and lose power), and I think it should handle third gear just fine. I pulled the jets and found: 25 pilots, stock needles in the middle position, and 320 mains. Does anyone have any thoughts on this jetting combo, or can you give a better solution. Thanks.

Read the jetting FAQ

 

clean the air filters

fresh plugs

put in a 32.5 pilot (buy 30 and 27.5's too)

(Motoworld had them in stock when i bought mine on tuesday)

I would go one clip up on the needle too but start with the pilots.

 

 

before i swapped to TORS eliminated carbs i was pulling 4th up olds :beer:

 

Good luck with your tuning. It takes patience

you really need to look at your compression................

 

if you dont have good rings and cyl walls you maybe loosing your power thru loss of intake and blow by!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
