Last year I installed a Cylinder Works 470 Big Bore Kit and a GYTR Head and Cams onto my 2013 YZ450F. It runs amazing! (Power is similar to that of the 2014/15 YZ450F) In the world of Professional Hillclimbing however, we use all the power we can get, so I am installing NOS to help my 470 compete!
Adding a Cold Fusion Nitrous Kit and larger radiators to my 470cc hillclimber!
Used right side lower motor mount bolt to mount the solenoids. Black line is fuel coming from splice/tee in the stock fuel line. Braided line is NOS.
Shown is the fogger installed into the air boot just upstream of the throttle body. Red is fuel, blue is NOS. I had previously installed the Twin Air Power Flow air filter kit on the bike which made the install abit easier.
Another pic of the solenoids with the fuel and NOS lines plumbed in.
Looking down into the intake with the air filter removed you can see the fogger tip from the inside.
NOS bottle mounted and braided line ran to bottle from solenoid.
I still need to install a custom throttle that has a micro switch welded into the mount which is set to actuate when I hit 3/4 throttle. I am powering the solenoids with a rechargeable R/C car battery mounted with Velcro, behind the front # plate. Once I get these next steps finished I will post more pics
