Thank you DM310 (Chris) for doing this in depth write up. It will be a huge help for those with the 08 carb model Teryx...
Ok so this is how I did it. Things you will need
Brute force Dyno jet kit p/n Q217 (thanks Sandjunkie)
Uni filters (clamp on, angled 15', 2.75" ID) p/n UP4275AST
2.75" exhuast tubing (only need about 5")
Poflo and Sandjunkie have posted great tips here and there on what needs to be done to the carbs. I jb welded the original holes on the bottom of the slides. Make sure its flush and smoth. I then used a 1/16th drill bit and drilled 2 new holes about 3/16" forward of the org holes. You can play around w/ the size of the holes, they might need to be a little larger if you are running a 840 kit. :think:
One more note is when you are putting the needle back in the slide, make sure the legs on the needle hat dont cover up either of the new holes that are drilled
The reason I used the Brute kit is its my understanding that the spring has less tension and the needles are a little richer, plus you get a lot more jets in the kit.
I set the idle screw to 3 turns out. The key to tuning cv carbs is to find the correct jet first under WOT and then tune mid range and idle. I welded some O2 bungs on the stock exhaust and picked up a bosch single wire o2 sensor from kragen. Its not as good as a wideband but it gets the job done plus it was only $20. I then used a fluke meter to monitor the voltage. Make sure the sensor it warmed up before testing.
I tested w/ the filters off first to confirm the slides were not bouncing around through out the rpm range. Then with the filters on I fine tuned it. I ended up with a 160 jet in the front and 165 in the rear. The front needle I set on the number 2 clip position w/ 2 washers. The rear needle I set on clip position 3 w/ 2 washers.
For the filters, I used the a section of 2.75" exhaust tubing so I could connect the filters to the stock carb boots.
My teryx is all stock except this intake and a Non-programable CDI
Throttle responce is instant, starts a lot easier, revs up a lot faster, and was a HUGE seat of the pants upgrade!! I hope this helps some people out :beer3:
Oh and one more note, you will have to add a breather set up as you will no longer have a plenum to attach the vent tube to. Sounds like a good reason to upgrade to this kit YFZ catch can and HW stop kit.. - Kawasaki Teryx Forum
added a pic to the write up
heres a quick video. The intake is louder than the exhaust
