99 400 Jetting? The link above doesn't work

[kx4life13]

Soo I ride in southern Utah and knolls and the pilot jetting isn't working right how I have it so what are recommended jettings

On my '99, what helped was a richer pilot jet - the stock 45 is just too lean for many conditions (and I'm surprised that in the Grays, link no one was using a richer pilot jet)

I believe I installed a 50, which helped a lot.

Well right now I'm running all stock except the pilot and it's a 42 and it's still running like crap in low throttle and too hot everywhere else
