Hey guys, I am stumped! I just rebuilt the top end in my bike stock everything piston/rings and I had the 00 valves put in my bike its a 01. Everything went back together smooth; but now when I go to kick her over she only wants to kinda start so i pull my hotstart and it starts for about 2 secs and shuts off. I figured it was jetting so, I went from a 45 pilot to a 40 and it kinda helped now I can get a blurp out of it with the choke on, where as I couldnt before. I am at 4500ft alt in arizona, if that helps any. Only things i have on it that are after market is a powerbomb header and a sparkarrestor end cap. I got it back together last weekend and have been trying to get her started for almost a week . Any help would be awesome, Thank you in advance! Oh ya the carb settings i ran before i did the top end was a 165 main 45 pilot and my stock needle is on the 4th clip, I am 2 turns out on my fuel screw.
