Did you try putting the stock air cleaner back on? It probably wouldn't run lean that way. Guess we could start up the K&N debate again. I personaly don't like them. Think they let in more dirt than the stock set up. More air, more dirt.

 

i wish that i had two new hos to pimp on, what bout yall?

 

I am running the 157.5 and the K&N filter. I hit 61.5 mph on the gps a week ago. The temperature was 10 degrees outside.
