This is the filter I got. http://www.bikebandit.com/bikemaster...od-air-filters Spendy but not as much as but similar to the K&N. I had to modify it a bit by grinding a groove around the clamping flange so that things would clear the throttle mech. Model # is 3070940. Works good and looks nice I think. If you click my picture on the thread you can see what it looks like installed on my bike. The small breather I got at work, 3/8' pipe thread fits and works real nice also. I only have the one place but seems like every time I need a tool it's not where it's suppose to be.

Does the sprocket go on with out any mods except the chain length? I see some are making spacers, grinding things and buying bolts.
