Ok so I have a 1980 cb750k. I recently turned it into a cafe racer. Eliminated the air box and rejetted the carbs. I run a 4-1 header with cycle x race slip on. I used velocity stacks for intakes. I jetted the carbs with cylinders 1,4 at a 127.5 main jet and cylinders 2,3 with a 125 main jet. All pilot jets are 80's.
My question is when I hit about 6000 rpm's my bike seems to stumble acting like its missing and or not enough fuel. It's not either one of those problems and I'm coming here for advice.
Let me know what you guys think.
