Installed 5.75 mikuni slide on bike (17 250sx). Bike runs fantastic on MX track for 4-5 minutes then develops a nasty hanging idle. Track is similar to southwick (sandy), just curious where to start?
current specs are:
37.5 pilot (42.5 stock)
43-73 needle clip 3
450 main
a/s 1 turn out
Needle issue or PJ?
Should I try 1 clip richer on needle or go to next richer needle?
Seems like anytime I get it to run perfect (Crisp?) I get a hanging idle after 4-7 minutes...thanks for the input

Also you need to let the bike warm up before jetting. That 5 mins on the track is about the time it takes to warm up fully.
