Anybody know perfect jetting for 05' 450x w/Hotcam Stg 1, full Ti-4 exhaust? I just rebuilt my motor due to intake valve problem. Since the rebuild it runs good but sometimes has weird hiccups that it never did before. Plus, I went from a stock cam to HC stg 1 and really don't feel like it is noticeable in comparison. I don't know what jets are currently installed but was wondering if any of you guys have figured out a good jet combination for this bike with these mods. I will be pulling it apart soon to check/adjust this. P.S. it has a new stock piston, stock bore. Thanks.

Welcome to the group! I highly recommend the JD Jetting kit. it has two custom tapered needles and the jets for your set up and location. here's a link:

You want that jet kit, and be sure to do the airbox mod described in the kit simultaneously. If the jetting and airbox are only running with stock jetting and a stock airbox no wonder there's no discernable differene. With that JD Jetting kit and airbox mod you're in for a heck of a treat. Doug

PS-This isnt launching the Space Shuttle either. The set-up is going to be the JD kit with its needle, a 165-170 main with a 45 pilot and the airbox mod. All must be done simultaneously too. Doug
