alright ever since i got my pipe on the 400ex and removed the lid.

Whenever i start it and rev it up so it will stay running(cold start) to warm it up, the Carb is Burping constantly like once every 5 seconds until its heated up. I didnt notice this before but it just catches my attention constantly.

Burping: just sounds like the air in it stops.

i got 38 pilot stock needle and 160 mainjets

is there any way to fix this or should i just leave it.

170 sounds a bit high I would just change the pilot jet and see what happens.
