Ive been waiting for a cheaper K&N intake to come out and there isnt anything under $130. Plus i wanted to get rid of the airbox. i took the ideas that King and Buddah did and made my own. This is just another example of what you can do instead of getting ripped off by trinity and pro flow.

I ordered a filter from k&n, costed $33. heres the link to it. Click

i started with a $5.99 3" diameter Exhaust extention that i got and autozone. The part that is slightly bigger to go adapt to the other exhaust pice works perfect for the intake boot to the efi. I cut a piece of the pipe with one side being the adaptor and the other just the 3" pipe.


I also bought some pipe clamping that works really good to go around the filter and strap it to the subframe. I havent gotten to ride it yet but it sounds a lot better. the throttle is really nice and it just sounds a lot meaner. Ill be able to try it out this weekend, drag racing at Pismo. I think it looks great and will work way better than a trinity filter stuck in the airbox, also $100 cheaper.

I dont know an outwerwear that will fit. That one on there doesnt fit, its too short. I got it from a z400 filter.

one problem though, For me, it runs crazy lean. I went to pismo for the weekdend and when i first rode it it was backfiring like crazy and after one drag race the efi light started blinking. at sea level it made it even worse. I had to put paper towels in the outerwear just to block some air flow. It kind of defeated the purpose of the intake. Ill have to get one of the efi controllers now but it will run even better with more air and more fuel.

Question?
What effect does the sensor have not being enclosed in the air box?

Being an air temp sensor,you think it would effect the fi programme as air density will make a huge difference in how much fuel is supplied. The sensor would need to be fitted somewhere it can get a true reading.

Could the sensor be fitted sheltered next to the filter or mounted into the adaptor tube?

Just a thought, any opinions?

you definetly want the sensor to get the same air as your intake will.having it to close to the exhaust or far away from the filter will throw it way off and will richen or lean your machine waay out.a few guys that have removed the airboxes and air running direct mount filters on cannondales are experiencing the same problem.the sensors are mounted on a plate but the plate is under the filter and over the engine.the heat from the engine as it warms up is throwing them off.a guy had his on the dyno a few weeks ago and could actually watch the afr change as the engine got hotter(more than normal).i think a small bracket on top or bottom of the metal adapter would be a god place.somewhat central of he exhaust but not next to it

You would think that as long as it is sheltered from general airflow, exhaust and engine heat, it would get a relatively good reading.
Instead of removing the airbox completely, cut out the back wall and cut the sides down on a diagonal?

At the end of the day, it still would be good to get a diagnostic check to see exactly how it runs.



Junkie, about your roo pics,
I have not seen a live one for quite some time now, there are just the usual suspects that have had a minor altercations with a semi trailers, generally leaving them spread from a$$hole to breakfast over the road!!

I am still looking however.
