I have a 1996 750 katana that I plan on putting on a go cart... carbs and jets have been extensively cleaned, and I've got it running off the choke but as soon as I give it throttle it dies out. I've had to cut the exhaust because of a rust issue so it is currently straight piped and I will be putting pod air filters on it... is this a jetting problem because of these modifications? I need some guidance
