Just a quick post with photos. Before: 2006 Uly, stock airbox, stock filter, stock crank-case breather route (into airbox), Special OPS pipe. After: Stock airbox cut, only top used to hold down a K&N air filter. Secured using threaded rod through the stock breather hose holes. Breather hoses joined to T-peice, long/thin hose running to a generic fuel filter acting as a catch can/filter. Thoughts after ~200km (in order of importance to me, haha): * Intake sound is AWESOME! * Noticeable power increase (can consistently pull clutch'less wheelies in 2nd gear now, previously needed clutch... that's how I measure real-world success of performance mods). * Easier access to air filter (to check after riding in dusty conditions, etc). * Now able to check crank case blow-by gases/splodge, makes me feel better knowing the hydraulic lifters are doing their job, etc. * Idle is low now, ~900->1000rpm. Post-mod: * Will do a TPS to restore idle. * Later will install TFI (which I have removed temporarily) and add some fuel.

You can get some plastic spacers that are intended to go over the nails that attach gutters to houses at your local hardware store for a few pennies. Those can be cut down to correct length to stop the cover from crushing down too much on the filter and allow you to tighten the wing-nuts so that the vibes don't loosen them. I did almost exactly the same mod on my bike using an 04 12 airbox cover, except I used a Norris Performance (guy that makes the American Sport Bike, or Drummer) catch can. I could not be more thrilled after draining the catch can a few times. Knowing that goo did not and will not go into my intake tract is wonderful. The sound and performance are even better. Great pics. Good job. BTW while I had the base of the airbox off of the bike I covered it in aluminum tape to reflect motor heat back down and out of the airbox. I don't know if there was any gain, but black absorbs and radiates heat better than any other color...just a thought. (Message edited by diablobrian on August 06, 2007) |
