Just got my 90 750 running yesterday, it was slow to warm up but once it did it ran great...completely stock, just went thru the carbs (3x) lol. I had good response, pretty smooth idle, all was good. I started on my exhaust yesterday and drilled/cut/hacked the back baffle plate out of it like I saw a guy do on his post 600. Sound is ok, but it runs like crap. Bogs down when I hit the throttle, will not run w/o choke. Did I loose enough back pressure to need to back out my a/f screws? running them at 2.5 turns with factory airbox. Thanks for the help!

Too much flow, not enough gas...
I would suggest a jetkit to help for best results. Turning out the air fuel/shiming the needles might help some in the interim.
