I have a 04 warrior hi comp piston, shaved head, port & polish, powerbomb header, whitebrothers exhaust, revbox, CFM alum. airbox w/K&N filter, 152.5 jet. main jet. The problem is When i get up in the mid-range into the topend it starts to break up or miss i think at 5000rpm & up approx. . Not sure what to do at this point should i keep jetting higher ? ditch the stock carb in favor of a bigger carb ? any input would be appreciated ....

 

step the size up on the main, warrior carbs can be a real pain, if you decide to get a carb get the Edelbrock Quicksilver, there very nice.
