Johnson/Stoddard 450 Riders

04 YZ450 high desert riders, what jetting specs you running? ThanX

I'm in Apple Valley, and I am running the JD Jet kit : 170 main, 48 pilot, Blue needle in 4th from top groove. Mine was so bad when I bought it new that I waited until I got this kit before I got to break it in. The most frustrating 2 weeks ever! :crazy: but it was definately worth it. No bog, no backfiring, and tons of power. :ride:

In Palmcaster, 440 kit with hot cams and 13.5:1 comp. I'm running a 168 main, JD red on the 4th clip, 42 pilot, 1 3/4 turns out on the fuel screw. I run a 50/50 mix of VP red and pump premium

ThanX guys, appreciate it, Ive got a JD kit, so your input is perfect :crazy:
