CRF450EXRACER

I just bought some PTR midrange pipes and need help on jetting it. Mains, pilots, needle.I also have a Pro Flow w/ Pro Design filter. Any help would be appreciated.

Hey Banchetta, I just bought ptr mids and want to know what mains,pilots,and needle setting you used. I bought them from a local dealer and did what they said to do. I went to 290 mains,30 pilots and moved the needle clip all the way up. It ran like crap. It bogged so much. So I put the stock pilots back in and messed with the needle and it still wouldn't run. . Im thinking the mains have to be smaller. But what did you do. I also have a Pro Flow w/ Pro design filter. When I was testing it, I ran it w/ nothing on the carbs. What do I do. Thanx.
