I've just ordered Hotcams for my YFZ450, what jetting if any will I need to do, here's what I have now (GYT-R Jetkit) 170 mainjet, 45 pilot, clip on #4 and air/fuel screw out 2.5 turns, am at around 1700 ft.
You should get a 48 pilot and a 175-178 main your needle should be fine
I am at sea level I ran a 48 p 2.0 screw Clip 4 and a 178 main after I put the hot cams in It was hard to start with the 45. try it with what you have first and go up from there :nod:
iv got some questions on hotcams. Even though it says dont get the springs, should you get them(pretty sure this is for stage 1), is it a b*tch to get the springs off? and i was there a noticable difference in power? oh and can you do the cam mod with the hot cams or is that only with the stock ones. Thanks
