My Banshee is bogging off idle .... need help

[screamin_mimi]

Head milled .030 ... Duncan High Rev's ... 300 main jet .... 25 stock pilot jet .... 15 tooth front sprocket (just changed from 14 - first riding after change) .... 93 octane fuel

 

Having a problem about half way through the RPM range -- just seems slightly boggy ... then when it hits over half way in the range -- she FLYS!!!

 

Could this be from he 15 tooth sprocket change? Thinking the 15 tooth might just be giving me a lot more power on the top end.

 

I did a spark plug check with mild riding - and it looks perfect.

 

Anyone have any ideas?

 

Main jet change? Pilot jet change? Reed issue? Sprocket?

 

Also ---- anyone who is thinking of milling their head --- DO IT!! This banshee is SCREAMIN'!!!!

 

THANKS!!!!!

x2^^^^

your running lean on ur pilot get 27.5 and start with 1 and 1/2 turns out on the air screw then tune from there the farth in u go the richer if you have to turn it in farther than 1 turn u need a bigger pilot

Thanks for the info --- I am also on the 3rd notch on the needle... should I move it to the 4th?

dont do more than one thing at a time,then u wont know what worked,start with the 27.5 pilots.90% of bikes respond better to that pilot with any aftermarket pipe.hell sometimes u gotta run a 30.do the 27.5,if its not better try richening needle after.
